Three dimensional dynamic measurements using a stereo vision system and optical flow algorithms.

Abstract

In this work we present a solution for a specific problems, by combining optical flow and stereo vision techniques, we obtain a three dimensional object tracking system capable two follow lateral, radial and depth changes varying in time. The optical flow algorithms allows the study of displacements varying in time and by using a stereo vision system we can retrieve the coordinates of the objects observed in the three axes (x, y, z) and therefore the reconstruction of such objects. Experimental results will be presented.
