Abstract: A system for the automated analysis of image quality obtained by a camera in a camera tunnel system includes a test pattern on an item for placement in the camera tunnel system and an imaging subsystem configured to capture an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern. The system further includes an image analysis tool configured to automatically identify and analyze the image of the test pattern for generating one or more image quality metrics.

Abstract: A parcel dimension measurement system includes image sensors oriented to image a parcel, an imaging subsystem configured to stitch together outputs of the image sensors to produce at least one two-dimensional image comprised of a plurality of pixels, and a general dimension subsystem including general parcel dimension information. A fine dimensioning subsystem is configured to determine dimension measurements of the parcel using the at least one two-dimensional image and the general parcel dimension information.

Abstract: A method and system for enhancing measurement of a bar code or other object includes storing a pixel image containing a bar code; determining bar code orientation relative to the stored pixel image; determining a scan track through the pixel image in a succession of pixel to pixel scan paths; determining the angle of each scan path relative to the bar code orientation; and adjusting the number of virtual pixels added to each scan path as a function of the scan path angle and the bar code orientation for equalizing the lengths, measured in pixels, of the scan paths though they are of different actual lengths due to differences in scan path angles.

Abstract: A barcode detection device is disclosed which captures an image; examines the image in a plurality of grids; obtains a profile of the image along the sides of the grids; determines the number of transitions in the profile of each side; compares the number of transitions in each adjacent pair of sides with the number of transitions in the opposing adjacent pair of sides, respectively, and identifies a potential barcode data bearing grid when the count of transitions on one pair of adjacent sides matches the count of transitions on the opposing pair of adjacent sides.

Abstract: A method and system for verifying readings of contrasting elements such as bar code elements includes generating a profile of the contrasting elements; identifying a first zone of values representing a first contrasting element, a second zone of values representing a second contrasting element, and a working zone of values representing transitions between contrasting elements; detecting a change in the bar code profile indicative of an apparent transition between the contrasting elements and confirming the apparent transition as a true transition if it occurs in the working zone and rejecting it if it occurs in the first or second zones.

Abstract: An optical device for reading one- and two-dimensional symbologies at variable depths of field. The device has a light source for projecting emitted light toward the symbol image to be reflected back to an optical assembly, or zoom lens. The zoom gives multiple field of view capability to a CCD detector for detecting the reflected light, and generating a proportional electrical signal. The sensor is aimed for reading the symbology by a frame locator including a light source that emits a beam divided by diffractive optics into beamlets matching the dimensions of the respective field of views. Refractive optics are shifted in response to movement of the zoom lens for aiming the beamlets to form an aiming frame in accordance with the depth of field selected by the zoom lens. The device includes a microcomputer that communicates with a host PC including an API library with downloadable applications for image processing, including segmenting, analyzing, and decoding.
