  • Patent number: 10346645
    Abstract: This invention provides an aimer assembly for a vision system that is coaxial (on-axis) with the camera optical axis, thus providing an aligned aim point at a wide range of working distances. The aimer includes a projecting light element located aside the camera optical axis. The beam and received light from the imaged (illuminated) scene are selectively reflected or transmitted through a dichoric mirror assembly in a manner that permits the beam to be aligned with the optical axis and projected to the scene while only light from the scene is received by the sensor. The aimer beam and illuminator employ differing light wavelengths. In a further embodiment, an internal illuminator includes a plurality of light sources below the camera optical axis. Some of the light sources are covered by a prismatic structure for close distance, and other light sources are collimated, projecting over a longer distance.

A field of view expander includes outer mirrors that receive light from different portions of a scene. The outer mirrors direct light to tilted inner mirrors of a beam splitter that directs the light aligned with a camera axis to avoid image distortion. The inner mirrors each direct the light from each outer mirror into a strip on the sensor, and the system searches features. The adjacent fields of view include overlap regions sized and arranged to ensure a centralized feature appears fully in at least one strip. Alternatively, a moving mirror changes position between acquired image frames so that a full width of the scene is imaged in successive frames.

    Abstract: An imaging reader is worn by a user. The reader has an imaging assembly that has a solid-state imager with an array of image sensors and a lens assembly. In a reading mode, the imaging assembly captures and projects light as an image onto the array. A controller detects a user's finger pointing at a symbol proximal to a tip of the finger in the image, and generates a control signal when the finger obstructs the symbol in the image. Upon receipt of the control signal, the controller automatically controls a drive to move the imager and/or a lens of the lens assembly to an adjusted position in which the symbol in the image is unobstructed by the finger. The unobstructed image of the symbol is processed into identifying data, and the data is transmitted away from the housing to a remote host device.

  • Publication number: 20140117092
    Abstract: A lightpipe, which is mounted on one chassis part of an imaging module of an imaging reader, optically modifies an aiming beam emitted by an aiming laser, which is mounted on another chassis part of the imaging module, to generate and shape an aiming light pattern on a target. In one embodiment, at least one, or both, of the chassis parts are movable relative to each other to spatially adjust the aiming light pattern relative to an imaging field of view. In another embodiment, the aiming laser and the lightpipe are received in respective pockets of the chassis parts with clearance, and are adjustably fixed in place to spatially adjust the aiming light pattern relative to the imaging field of view.

  • Publication number: 20140070007
    Abstract: A barcode reading method and a barcode reading device are provided. An image sensor is utilized to capture an image of a barcode via an optical lens, and then a triangulation method and an ideal lens imagining method are collocated to calculate the digital image so as to produce an optimum image distance. A distance between the image sensor and the optical lens is then adjusted in accordance with the optimum image distance, so that the barcode can be immediately and clearly imaged on the image sensor.

  • Patent number: 8561906
    Abstract: Optical reading system and methods having multiple modes of operation, for example: omnidirectional and single-code picking; fixed and handheld reading; 1D and 2D code reading. In one configuration, an image-based system obtains input data via an area sensor (e.g., a 2D CCD array) with only data corresponding to a pattern of virtual scan lines being stored and processed. A user may implement different operating modes such as a first mode reading codes in any location or orientation and a second mode reading only a code oriented along a particular virtual scan line or group thereof. Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change within or between frames.
