Description

This application is a Continuation in Part, and claims the benefit of U.S. application Ser. No. 11/176,423, filed on Mar. 10, 2005.

FIELD OF TME INVENTION

The present invention is in the general field of obtaining an outline of primary eyewear, such as eyeglasses, for generating secondary eyewear, such as clip-ons whose lenses are readily mountable on and in registration with the eyeglass frame.

BACKGROUND OF THE INVENTION

There are known in the art many types of add-on units that are fitted onto eyeglass frames or lenses. An example is a clip-on that matches in size and shape the eyeglass frame or lenses and is configured to be readily mounted thereon. Typically, such a clip-on has dark lenses, and when used, can convert conventional eyeglasses (having optical lenses) to sunglasses. Clip-ons are thus quite popular, since they are compact and insofar as the user is concerned, the need to have separate optical eyeglasses and sunglasses is obviated.

US 20030101603 (hereinafter, “the US application”) of the applicant, discloses a system for imaging a pair of eyeglasses and obtaining data indicative of the outline of the eyeglasses and designated locations associated with the outline. The system is useful for custom forming, on a non-industrial scale, clip-ons adapted to be used with eyeglasses. The system includes a positioning device for placing the eyeglasses thereon, an imaging device for acquiring an image of the eyeglasses, a processor associated with a cutting machine, in which the clip-ons, with their associated holes and slots, are cut according to an editable outline and supplemental locations, the processor being configured to calculate an editable outline for each eyepiece of the eyeglasses and a display to display the outline, such that the editable outline can be compared to its respective eyepiece. The processor is further configured to calculate supplemental locations linked to the outline for manufacturing holes and/or slots that anchor clip-on parts that include bridge and legs, and to provide data indicative of the specified outline and supplemental locations.

SUMMARY OF THE INVENTION

According to one aspect of the present invention, there is provided a method of providing image information regarding primary eyewear to a remote production center where secondary eyewear is to be produced based thereon. The method comprises the steps of obtaining with an imaging device an image of the primary eyewear suitable for obtaining therefrom image data indicative of at least one geometric characteristic of the primary eyewear, providing to the production center reference data associated with the primary eyewear, and transmitting the image data via an external communication means to the production center for production there of the secondary eyewear based on the image and reference data. The reference data is representative of at least one reference dimension.

It should be noted that hereinafter in the specification and claims the term eyewear is to be understood as eyeglasses, sunglasses, eyeglass frames, clip-on attachments for eyeglasses, and the like. It should further be noted that the term remote, as it relates to a production center, is to be understood as at a site different from the imaging device. Conversely, with regard to an imaging device, the term remote is to be understood as at a site different from the production center. The term external, as it relates to a communication means, refers to a third-party communication infrastructure, such as the PSTN, cellular communication backbone, the internet or the like.

At the production center, the image data may be manipulated so that the secondary eyewear will be produced having a size and shape that correspond to those of the eyeglasses.

According to one embodiment, the imaging device comprises a camera objective and a CCD (e.g., a digital camera). According to one modification of this embodiment, the imaging device is integrated with a cellular communication device, which may be adapted to transmit at least the image data to the production center.

According to another embodiment, the imaging device is a photocopying machine. According to a further embodiment, the image data is transmitted using a facsimile machine.

When desired, the production center may comprise means to convert an image to digital data, such as a computer scanner.

The reference data may include two mutually perpendicular dimensions. These may by measurements of the height and width of at least part of the primary eyewear. Alternatively, these may be provided by imaging an object of known dimensions, such as a sticker placed on the primary eyewear during imaging, providing the reference data.

According to another aspect of the present invention, there is provided a platform, adapted to hold primary eyewear and an imaging device at a predetermined mutual disposition, such that the imaging device is positioned to image the primary eyewear.

According to one modification, the platform comprises a cover adapted to prohibit lighting conditions unfavorable to clearly imaging the primary eyewear. According to another modification, the platform comprises a backlight positioned so that the primary eyewear is retained between it and the imaging device. The intensity of the light may be adjustable. According to a flier modification, the distance between the primary eyewear and the imaging device may be adjusted. According to a still further modification, the primary eyewear is eyeglasses, and the platform is adapted to hold the eyeglasses such that the temples are not imaged by the imaging device. According to a still further modification, the platform is adapted to hold a cellular phone having a digital camera integrated therein.

It is particularly advantageous that the platform be adapted to hold the eyeglasses at a predetermined position. Therefore, according to a further aspect of the present invention, there is provided a positioning system for use with a platform as disclosed above and designed to arrange the eyewear such that a front face thereof is at a predetermined orientation of the imaging device. The positioning system comprises an alignment device having an eyewear supporting portion and an alignment portion. The alignment portion is adapted to bear against the front face of the eyewear and, at least in use, positioned so as to impart the orientation to the eyewear. The predetermined orientation is preferably such that the front face is perpendicular to the optical axis of the imaging device.

The alignment portion of the alignment device may comprise pads positioned so as to bear against the eyewear. In this way, the lenses of the eyewear are not scratched or otherwise marked by the alignment device.

The positioning system may further comprise grips held within a back panel of the platform. Each grip is adapted to tightly grasp a temple of the eyewear, at least when said eyewear is arranged by the alignment device. This ensures that once the eyeglasses are properly positioned, they are not dislocated by vibrations or other disturbances.

The grips may each comprise an opening adapted to permit substantially frictionless insertion of the temple therethrough, and a slit, extending therefrom, adapted to provide said grasping.

According to a still further aspect of the present invention, there is provided a platform adapted to hold primary eyewear and an imaging device in mutual disposition. The platform comprises a back panel and a support. The back panel comprises apertures. The support is adapted, together with the apertures, to carry the eyewear. The apertures are located with respect to the support so as to dispose the eyewear in a predetermined disposition. The bottoms of the apertures may be located substantially lower that the support, so that eyewear having a high pantoscopic angle may be disposed so that its front face is substantially perpendicular to the optical axis of the imaging device.

According to a still further aspect of the present invention, there is provided a method of imaging primary eyewear for determining the geometry of a front face thereof, wherein the eyewear is imaged from at least two vantage points. The at least two vantage points may be mutually perpendicular. One of the vantage points may be from the front of the eyewear.

According to a still further aspect of the present invention, there is provided a production center comprising a processor adapted to receive and process images of primary eyewear acquired by a remote imaging device, to determine the real size of the primary eyewear, and to generate instructions for the production of secondary eyewear based thereon. The production center further comprises a production machine adapted to receive the instructions from the processor and to produce the secondary eyewear based thereon.

According to one embodiment the processor is further adapted to calculate an editable frame outline of the primary eyewear. According to another embodiment, the processor is further adapted to calculate supplemental data for the production of the secondary eyewear. The supplemental data may be locations associated with the outline for attachment of anchoring parts. The processor may comprise several computers.

The present invention has several advantages, among which is the possibility of producing custom eyewear, such as clip-ons, made to be used with primary eyewear, such as eyeglasses, without requiring a customer to be in proximity to a production center. A system or network comprising a production center and a plurality of remote sites provided with an imaging device may be established, enabling a customer to have his eyeglasses imaged at a site convenient to him, and have clip-ons produced at the production center and sent to him.

DETAILED DESCRIPTION EMBODIMENTS

FIG. 1 is a schematic representation of a system using a method for producing clip-ons for eyeglasses by a production center 22 using a remote imaging device 18, in accordance with one embodiment of the present invention. In this case, eyeglasses constitute primary eyewear, and clip-ons constitute secondary eyewear.

According to the method, a customer brings his eyeglasses to one of several remote sites 20. Each remote site comprises an imaging device 18 for imaging eyeglasses and equipment for transmitting the image to the production center over external communication means.

The imaging device 18 is preferably a digital imaging device such as a cellular phone equipped with a camera objective and a CCD, but it may be any device adapted to acquire an image and convert it to a digital bitmap that can be transmitted, including, but not limited to, a digital SLR camera, a digital video camera adapted to capture “still” pictures, a webcam, a computer scanner, a fax machine, or fax software. The imaging device 18 may be a camera objective and a CCD in an e-mail enabled cellular phone. In this way, a digital image may be acquired and transmitted from a single piece of equipment at the remote site 20. Alteratively, the device 18 may be a non-digital imaging device such as a conventional camera. In that case, the image may be converted to a digital bitmap either at the remote site 20 or at the production center 22.

The image, having been acquired at the remote site 20, is transmitted to the production center 22 via the external communication means. When the remote site transmits a digital file, either acquired directly by a digital imaging device, or converted from an image produced by a non-digital imaging device, the equipment may be any device capable of sending digital files via a public communication network 24, preferably using electronic mail, but it may use any appropriate protocol, including, but not limited to, a VPN tunnel designated for that purpose or an open file drop-off server.

In the case that an image has been captured by a non-digital imaging device and has not been converted to a digital format at the remote site, the external communication means may be, for example, a courier or the PSTN. In the case that the PSTN is used as the external communication means, a fax machine or fax software may be used. Once the image is received by the production center, it is converted to a digital format. Alternatively, the production center 22 may be provided with software adapted to receive a fax transmission and automatically convert the transmission to a digital image.

In addition, reference data which is used to determine the real size of the eyeglasses is also provided to the production center. This information may comprise measurements of the height and width of at least one of the eyeglasses' lenses. In the art, and subsequently in this specification, these are referred to as A (width) and B (height) dimensions. These measurements are transmitted to the production center with the image, in order to determine the actual size of the glasses. Alternatively, this information may be a predetermined dimension, such as the distance between the imaging device and the eyeglasses, or a reference dimension imaged together with the eyeglasses, may be used to determine, at the production center, the real size of the glasses.

As shown in FIG. 7, a sticker 30 of known dimensions may be placed on the lens of the eyeglasses during imaging. Use of the sticker 30 obviates the need to take A and B measurements of the eyeglasses. When the image of the eyeglasses with the sticker 30 is transmitted to the production center, it is scaled so that the image of the sticker represents the known true size of the sticker. This ensures that the image also reflects the true size of the eyeglasses.

It should be noted that the entire front of the eyeglasses need not be imaged. It is sufficient that an area encompassing one entire lens and the entirety of the bridge be imaged. Since eyeglasses are typically symmetrical about the bridge, the image of the lens not imaged can be extrapolated by the processor. In the event of non-symmetrical eyeglasses, both lenses must be imaged.

In operation, the image of the eyeglasses is transmitted to the production center, for example, via electronic mail. Included in the transmission may be information about the eyeglasses and/or clip-ons, including, but not limited to, lens type, lens color, hardware color, curvature of the eyeglasses (base 6/8), and glasses and frame thickness. Upon receipt of the transmission, an order is opened and an order number assigned. A physical ticket, having the order information encoded on a barcode is printed, and the order is placed in a job queue. The ticket is associated with a tray. When the tray reaches a dispatcher, the order is retrieved from the system using the encoded information. The order information is retrieved, the clip-ons are produced (as described below), and the order information is copied to a data server, which is periodically backed up.

Prior to production, the image is scaled, based on the information provided, to represent the actual size of the eyeglasses. In the event that A and B dimensions are sent, this is accomplished by considering the width, in pixels, of the A dimension of the image of a lens, and dividing it by the measured A dimension. This ratio is used to horizontally scale the image. A similar calculation is performed for the vertical dimension of the image. These two calculations are carried out independently of one another, since, especially in the event of a facsimile transmission, one dimension may be disproportionately “stretched” or “compressed,” resulting in a distorted image. In the event that the distance from the camera objective to the eyeglasses or the imaged reference dimension is sent, the size of the eyeglasses may be geometrically extrapolated from that information and from the size of the image of the eyeglasses.

Sending the A and B dimensions has the advantage that in a case where the front face of the eyeglasses has a significant curvature, the geometric extrapolation used to determine the size of the eyeglasses will be flawed, since that calculation is based on an assumption of a planar eyeglasses front face.

The image is analyzed by the processor in order to determine the location of the edges of the eyeglasses. Due to noise inherent to digital imaging, the edge detection may be enhanced by the algorithm described in the US application, paragraphs 109 to 121, which are incorporated herein by reference.

Generally speaking, the outline of the eyeglasses is sought. Where, for example, the eyeglasses include a frame, the sought outline is the external outline of the frame. By another example, where the eyeglasses are rimless (i.e., they have no frame), the sought outline corresponds to the external margins of the eyeglass lenses.

It should be noted that redundant eyeglass parts, such as the temple and bridge, do not constitute parts of the sought outline.

Specific procedures are performed by the processor concerning image alignment and enhancement, as described in the US application, paragraphs 130 and 131, and, more explicitly, paragraphs 145-179, which are incorporated herein by reference along with the figures referenced therein.

One important feature is that the outline is editable, as it is displayed in a manner which enables the user to compare the outline to the respective eyepiece contour (e.g., in the case of eyeglasses with a frame, to the external contour of the frame). By one embodiment, the outline is superposed on the frame image, and is displayed in a distinguishable manner, for example, by displaying the frame image in one color and the outline in another color. Due to the editable characteristics of the outline and the fact that it can be easily compared to the eyeglasses' image, the user can readily apply minor modifications, if necessary, in order to adjust the outline to substantially match the contour of the eyeglass fame and thereby assure substantial registration of the so-manufactured clip-on with the eyeglasses. The modifications can be realized by an interface, e.g. as provided in commercially available drawing software (such as Free Hand™).

The processor further calculates supplemental data (e.g., locations of holes and slots to which clip-on parts such as the clips and bridge are to be anchored).

The outline and supplemental data are provided to a production machine, which cuts the clip-on lenses and produces the holes at the designated locations (as prescribed by the supplemental data) to thereby facilitate the assembly of the clip-on. Once assembled, the clip-ons are sent either to the customer or to the remote site for customer pick-up.

Each remote site 20 is preferably provided with a support on which eyeglasses may be disposed for imaging. It may further be provided with means for holding the imaging device. The eyeglasses support and the imaging device holding means may constitute parts of a platform 10.

FIG. 2 shows one embodiment of such a platform. The platform 10 comprises a grip 12 which may be made of molded plastic adapted to grasp a specific imaging device. Alternatively, the grip 12 may be made of a viscoelastic material, or of any material suitable to retain the imaging device 18, without causing damage thereto, so that the camera objective is disposed toward a support 14, and the shutter release button is accessible. The grip 12 may be easily adjustable to retain a range of imaging devices, for example, a range of cell phones enabled with digital cameras so that the imaging system is not limited for use with one or a few models of cell phones. It may optionally be removable from the platform 10, and replaceable by another grip adapted to hold a different range of imaging devices, such as substantially different cellular phones or a digital SLR camera.

The support 14 is adapted to retain the eyeglasses so that the front face thereof is facing the camera objective of the digital imaging device, and is substantially parallel to the CCD of the imaging device. In this way, the distortion of the image of the eyeglasses is reduced. The support 14 may be adapted to retain the eyeglasses in such a way so that the temples are not seen, such as with two or more slits or apertures positioned to receive the temples in such a way to that the eyeglasses are positioned as described above. When the eyeglasses are thus held, the stems are not viewable by the digital imaging device 18.

A backlight illumination source may be disposed such that the eyeglasses are retained between it and the digital imaging device 18, all having a common optical axis passing through the CCD. It is useful for eliminating shadows that would increase the amount of editing needed by the acquired image. The intensity of the light is optionally adjustable.

The platform 10 may optionally comprise a portion, disposed behind the glasses, having a regular pattern. In this way, the edges of frameless or partially frameless lenses can be determined by a user when the image is edited by the distortion of the pattern due to the eyeglass lens. The pattern may be colored, and the colors may be selected so that they do not substantially appear in the frame of the eyeglasses. In this way, a software filter may be provided to selectively remove or ignore the pattern during processing.

The platform may optionally comprise more than one section, thus permitting the support to be moved further away from or closer to the grip.

FIGS. 3, 4, 5, and 6 illustrate different embodiments of the platform.

The platform may further be provided with an alignment device adapted to retain the eyeglasses so that they are secured in a position such that the front face thereof is perpendicular to the optical axis of the imaging device.

One embodiment of such an alignment device, generally indicated at 32, is illustrated in FIGS. 8A and 8B, and is shown in FIG. 9 used in conjunction with the embodiment of the platform 10 illustrated in FIG. 6. In the embodiment of the platform 10 shown, a back panel 15 constitutes the support. The alignment device 32 comprises a support leg, generally indicated at 34, and a positioning arm, generally indicated at 36.

The support leg 34 comprises a base portion 38 having longitudinally extending bosses 40 adapted to be slidingly and snugly received by a corresponding portion of the platform 10. It also comprises a post 40 which extends vertically upwards from the base portion 38 when the alignment device 32 is received by the platform 10. Two planar arm guards 42 project parallely from one side of the post, forming therebetween an arm-receiving groove 44. The support leg 34 further comprises a bridge support 46 extending horizontally from the top of the post 40, in a direction opposite that of the arm guards 42. A first piece 48a of a magnet locking mechanism is received adjacent the top of the post. The first piece 48a of the mechanism may be a disc made from a ferromagnetic material flushly received within the post 40.

The positioning arm 36 comprises a cantilever arm 50 and a crosspiece 52. The cantilever arm 50, at a first end, is swingably articulated to the post 40 of the support leg 34 between a downward position and an upward position, and, at a second end, to the midpoint of the crosspiece 52. It is sized so as to be received within the arm-receiving groove 44. The crosspiece 52 comprises, at each end, a pad 54, preferably made from a viscoelastic material. The pad 54 is adapted to bear against the lens of a pair of eyeglasses without leaving substantial residue which would be difficult to remove. The crosspiece 52 further comprises, at its center, a second piece 48b of the magnet locking mechanism. The second piece 48b of the mechanism located so that it lies adjacent to the first piece 48a of the mechanism when the cantilever arm 50 is in the upward position, It is made of a material which is selected so that it cooperates with the first piece 48a of the mechanism for magnetic attraction.

The back panel 15 of the platform 10 is provided with two viscoelastic grips 56 which further aid in the alignments of the eyeglasses. FIG. 10 illustrates a grip 56 in more detail. The grips 56 are adapted to fit within apertures 58 of a back panel 60 of the platform 10 (see FIG. 9). Each grip 56 comprises an opening 62 near one end, and a slit 64 extending from the opening toward the other end of the grommet, generally along a longitudinal midline thereof. The opening 62 is sized so as to permit, when the grip 56 is inserted in an aperture 58, to allow for substantially frictionless insertion of the temple of the eyeglasses therethrough. The slit 64 is sized so as to provide, when the grip 56 is inserted in the aperture 58, a tight grasp on a temple within a range of widths (e.g., up to 4 mm, from 2 to 6 mm, etc.).

In use, the alignment device 32 is positioned in the platform 10 such that the post 40 is disposed in a generally vertical orientation. The grips 56 are inserted in the apertures 58 of the back panel 60 and oriented so that the openings 62 are disposed upwards. A pair of eyeglasses is placed on the platform 10 so that its bridge rests on the bridge support 46. The temples are slid downwardly so that they are gripped within the slits 64 of the grips 56. The positioning arm 36 is moved to the upward position, and the eyeglasses are adjusted to that the lenses bear against the pads 54. The eyeglasses are thus securely retained so that the front face thereof is substantially perpendicular to the optical axis of the imaging device.

In order to provide a platform 10 which can support a wider range of eyeglasses so that their front faces are substantially perpendicular to the optical to axis of the imaging device, the apertures 58 thereof may be formed so that they extend low down. This allows a pair of eyeglasses having a high pantoscopic angle to be positioned with its lenses substantially perpendicular to the optical axis of the imaging device, as illustrated in FIG. 11.

As an alternative to using a modified platform 10 as described above, a method of acquiring images of the eyeglasses may be carried out. The method is directed toward producing a final image of the front face of the eyeglasses which accurately represents its real dimensions, while taking into account the fact that the front face may not be perpendicular to the optical axis of the imaging device when imaged. According to the method, the eyeglasses are imaged from the front and from at least one other vantage point being generally orthogonal thereto, such as from the side or from above. In this way, if a pair of eyeglasses has, e.g., a high pantoscopic angle, the amount of compensation needed when processing the images can be determined by comparing the two images. The pantoscopic angle can be determined from the side image. Using trigonometric functions, this angle can be used to determine the true shape of the front of the glasses from the front image. Similarly, the true shape of the front of eyeglasses which are imaged when they do not line perpendicular to the optical axis of the imaging device can be found. This is accomplished by determining the angle by which the front face of the eyeglasses deviates from the plane which is perpendicular to the optical axis of the imaging device.

Reverting to FIG. 1, the production center 22 is equipped with a processor 26 and a production machine 28 for producing clip-ons. The processor 26 comprises a user interface and is adapted to receive a remotely acquired image, e.g., a software encoded bitmap or vector graphic, and the reference data used to determine the real size of the eyeglasses.

The production machine is adapted to receive data from the processor, and to produce, in accordance with the data, clip-ons. The production machine may be a milling machine adapted to shape the lenses of one or more clip-ons, drill holes and generate slots, thereby facilitating manufacture, on a non-industrial scale, manufacture of specified clip-ons that match the eyeglasses.

The processor is adapted to receive and process, using the reference data, images of eyeglasses acquired by the remote imaging device 18 at the remote site 20. The processor may comprises a CPU, volatile and non-volatile memory, a user interface, which includes a display and one or more input devices, an interface adapted to communicate with the production machine, and may further include an interface adapted to communicate with a public communication network, such as a LAN, a WAN, the internet, or the PSTN. The processor is also provided with software enabling the functionality described below.

The processor may be adapted to receive images in many formats, including, but not limited to, one of several bitmap or vector formats, with no requirements with regards to noise, white balance, exposure, etc., provided that the image accurately represents the eyeglasses, or can be manipulated in such a way so that it does, such as described below. The processor is adapted to convert the file to a preferred format which the software is adapted to manipulate.

The processor is adapted to receive, or have inputted, information which is used to determine the real size of the eyeglasses. In the event that the information is the A and B dimensions of the eyeglass lenses, the processor is adapted to scale the image horizontally and vertically as described above. The processor may carry out these two calculations independently of one another, since, especially in the event of a facsimile transmission, one dimension may be disproportionately “stretched” or “compressed,” resulting in a distorted image. In the event that the distance from the camera objective to the eyeglasses or the imaged reference dimension is sent, the processor is adapted to geometrically extrapolate the size of the eyeglasses from the information and from the size of the image of the eyeglasses.

The processor is adapted to produce an editable outline of the eyeglasses from the properly sized image. They allow, via the user interface, for the outline to be manually edited. The processor is further adapted to allow for features to be removed or added, as described above. The processor uses the edited outline data to generate commands which are sent to the machine, which produces the clip-ons based on this information.

The processor is adapted to represent the image of the eyeglasses correctly on the user interface. In the event that the user interface comprises a monitor with different vertical and horizontal dimensions for the display pixels, the processor is adapted to compensate for this discrepancy and correctly represent the outline of the eyeglasses to the user for any given monitor.

The processor may also be adapted to acquire an image of eyeglasses locally as described in the US application. In that case, the processor is adapted to indicate which images were captured locally, and which were received from a remote imaging device.

The processor is adapted to process non-digital images. For example, a remote image may be received by a facsimile machine, and the printout converted to a digital image, e.g., by a computer scanner. Processing then continues as described. Alternatively, images may be received in a traditionally photographic medium, either as photographs, photographic negatives, or exposed film. The processor may be adapted to scan photographs and/or photographic negatives. In addition, the production center may further comprise means for developing exposed film.

The processor may comprise software filters used in processing the image, which may include, but are not limited to, noise reduction.

The processor may be adapted to store particulars about the eyeglasses. These particulars may include, but are not limited to, customer information, the manufacturer of the eyeglasses, their model number, and size information. This information may be selectively stored in a database on the machine along with the final edited outline, Based on this, a customer may request additional clip-ons without having his eyeglasses re-imaged. Additionally, a request for clip-ons to fit eyeglasses which are equivalent to one already in the database may proceed directly to production without having to convert and edit the image as described above.

It should be noted that the production center may comprise more than one processor and more than one production machine.

Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations and modifications can be made without departing from the scope of the invention mutatis mutandis.
