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.

Claim (Index 1):
A machine vision system comprising:\n a first image capture device configured to image a first portion of a target surface from a first viewpoint; a second image capture device configured to image a second portion of the target surface from a second viewpoint, wherein the first portion of the target surface at least partially overlaps the second portion of the target surface; a machine vision processor connected to the first image capture device and the second image capture device, the machine vision processor configured to:\n acquire a first image of the target surface from the first image capture device; \n acquire a second image of the target surface from the second image capture device; \n rectify the first image to form a first rectified image and rectify the second image to form a second rectified image; \n retrieve a disparity field that provides mappings from a first plurality of coordinates in the first rectified image to a second plurality of coordinates in the second rectified image; \n generate difference data by comparing, based on the mappings of the disparity field, a first plurality of image elements in the first rectified image to a second plurality of image elements in the second rectified image; and \n determine whether the difference data is indicative of an object on the target surface.
