  • Detecting object presence on a target surface
    Patent number: 11763444
    Abstract: Described are methods, systems, apparatus, and computer program products for determining the presence of an object on a target surface. A machine vision system includes a first image capture device configured to image a first portion of a target surface from a first viewpoint and a second image capture device configured to image a second portion of the target surface from a second viewpoint. The machine vision system is configured to acquire a first image from the first image capture device, a second image from the second image capture device, rectify the first image and second image, retrieve a disparity field, generate difference data by comparing, based on the mappings of the disparity field, image elements in the first rectified image and a second image elements in the second rectified image; and determine whether the difference data is indicative of an object on the target surface.
    Type: Grant
