abstract:

A new algorithm to recover depth from a sequence of two or more stereoscopic images is presented. The algorithm, which uses a dynamic programming approach, builds a dense depth map and allows the camera displacement between each image to be any combination of rotation and translation. Since no «smoothing constraint» on depth is used, occlusions and depth discontinuities along the border of objects are preserved and easy to identify. For a given cost function, the algorithm finds the optimal cor respondence along epipolar lines. In our case, this function is the difference of intensities between corresponding points, adjusted with a factor accounting for occlusions. Tested on non-trivial synthetic image sequences with true depth map available, w e obtain a mean disparity error of less than one pixel
