Here, we propose realistic methods measuring three-dimensional (3-D) depth map by digital sequential image processing. Three different approaches as representative techniques for optical flow analysis are developped from 1) the gradient-based method, 2) the matching method and 3) our spatio-temporal mutual-correlation method. A simple idea of the motion stero with translational displacement of a camera is introduced in the analysis. Utilizing artifitial image sequences and real dynamic scenes, an accuracy and a resolution of these methods are tested. We clarified that the spatio-temporal correlation method is superior in accuracy of the optical flow velocity. The occulusion problem is discussed briefly.
