Abstract: Providing a disparity map includes acquiring first and second stereo images, binarizing the first stereo image to obtain a binarized image, and applying a block matching technique to the first and second stereo images to obtain an initial disparity map in which individual image elements are assigned a respective initial disparity value. For each respective image element, an updated disparity value that represents a product of the initial disparity value assigned to the image element and a value associated with the image element in the binarized image is obtained. An updated disparity map can be generated and represents the updated disparity values of the image elements.

Abstract: The present disclosure describes structured-stereo imaging assemblies including separate imagers for different wavelengths. The imaging assembly can include, for example, multiple imager sub-arrays, each of which includes a first imager to sense light of a first wavelength or range of wavelengths and a second imager to sense light of a different second wavelength or range of wavelengths. Images acquired from the imagers can be processed to obtain depth information and/or improved accuracy. Various techniques are described that can facilitate determining whether any of the imagers or sub-arrays are misaligned.
