A technique for constructing depth map from images of orthogonally-divergent fisheye stereo

Abstract

The issues of using a pair of orthogonally-divergent cameras with fisheye lenses in computer vision systems are considered. An algorithm has been developed for processing frames received from cameras to obtain a pair of rectified images. For a virtual model, the accuracy of constructing a scene depth map in the area of intersection of the cameras' fields of view was estimated.
