摘要
A device for accelerating calculation of the centroids of markers in a system for real time motion analysis is described, said system utilising images taken cyclically by a plurality of television cameras to follow the movements through time of a plurality of markers, each of which occupies a plurality of elementary units (pixels) of each television image frame: the centroid of these pixels indicates the instant position of the corresponding marker. The device according to the invention selects from the pixels of a set zone of a television image frame those occupied by the same marker and transfers these simultaneously to the circuit for calculation of the centroid.
