    摘要: Systems and methods are disclosed for circular stitching of images. For example, methods may include accessing a first image captured using a first image sensor; accessing a second image captured using a second image sensor; determining a cost table for a circular stitching boundary that includes overlapping regions of the first image and the second image; determining an extended disparity profile based on a periodic extension of the cost table and a smoothness criterion, wherein the extended disparity profile has a length greater than the width of the cost table; determining a binocular disparity profile of a length equal to the width of the cost table based on a contiguous subsequence of the extended disparity profile; and stitching the first image and the second image using the binocular disparity profile to obtain a combined image.

    摘要: A machine vision-based method and system for locating an object within a scene are provided. The method includes uniformly illuminating a target surface of the object within the scene with light having an intensity within a relatively narrow range of wavelengths such that the light overwhelms the intensity of ambient light within the narrow range to obtain reflected, backscattered illumination. The method also includes sensing brightness of the surface due to a diffuse component of the backscattered illumination to obtain brightness information. Backscattered illumination from the target surface is inspected to obtain geometric information. Rotationally and positionally invariant surface albedo of the object is computed based on the brightness and geometric information. The surface albedo and the geometric information may then be used by a matching algorithm.

    摘要: Systems and techniques are described for determining disparity information. For instance, a method for determining disparity information is provided. The method including: obtaining a plurality of cost functions; determining a first disparity for a center pixel of a first region of pixels at least in part by comparing one or more minima of a cost function of the center pixel to one or more minima of cost functions of other pixels in the first region; determining a second disparity for the center pixel at least in part by comparing one or more minima of a cost function of a center pixel of a second region to one or more minima of cost functions of other pixels in the second region, including the center pixel of the first region; and determining a third disparity for the center pixel of the first region based on the first disparity and the second disparity.
