摘要： A method and apparatus for verifying a pattern by mapping a grid onto a template that defines a plurality of grid sections. A digital image may be taken of a container showing an identifying mark (or lack thereof). The template and/or grid may be scaled and/or translated to match a perspective of the identifying mark as depicted in the digital image. A correlation function compares individual grid sections to portions of the digital image to find portions that maximize a correlation score. Grid sections with low contrast may be skipped and/or combined with higher-contrast sections to compute a score. If a match condition is satisfied between at least some of the grid sections and the digital image of the identifying mark, the pattern has been verified.

摘要： At least some embodiments of the present invention relate to methods for stitching barcodes captured over multiple images. In an embodiment, the method includes capturing a first and second portions of a barcode in respective images, determining a presence of a match between the two captured portions, stitching the two portions pursuant to the match, and validating the combined string with the assistance of a reference mark.

摘要： A method of operating a workstation includes capturing multiple monitoring images each being captured with the imaging sensor while the illumination light source is energized during one of multiple short exposure-time-periods, and detecting a checkup-condition that includes analyzing the multiple monitoring images to determine the presence of any adverse feature on workstation's window. Each of the multiple short exposure-time-periods is shorter than four times of a threshold exposure-time-period but no shorter than 25% of the threshold exposure-time-period. The threshold exposure-time-period is a minimal exposure-time-period needed for the imaging sensor to capture recognizable patterns of a barcode that is in directing contacting with the window while the illumination light source is energized.

摘要： An imaging barcode scanner and method are provided. The scanner includes a first array of photosensitive elements having a first field of view traversing a window and intersecting a work surface at a first angle, and a second array of photosensitive elements having a second field of view traversing the window and intersecting the work surface at a second angle. The scanner also includes a processor configured to: receive a first image of the work surface from the first array of photosensitive elements, and a second image of the work surface from the second array of photosensitive elements; register the first image with the second image; and generate an enhanced image of the work surface based on the registered first image and second image, the enhanced image having a greater pixel density than the first image and the second image.
