An algorithm for the computation of 3-D coordinates (space intersection) of marked points on a moving subject surveyed by a pair of TV cameras is presented. It has been designed to meet the requirements of routine analysis in biomechanics laboratories. 3-D geometrical arrangement of the TV cameras (space resection) is obtained by means of a method based on an iterative least-squares estimation, and requires little time for calibration operations; 3-D coordinates are computed by means of a fast… CONTINUE READING
