摘要：The optical flow analysis is presented as a useful tool to characterize the movement of a body in an automatic way using a digital video. This technique allows to substitute a complex experimental set-up by a video recording system, which is easily available since the large development in the last years of the multi-media systems. Some results obtained from the analysis of different experiments are shown and the possible use of this kind of technique in a teaching laboratory is discussed.
