Motion Capturing


The moving objects the bumper cars are captured optically by video cameras mounted along the length and width of the Autodrom. Each car is identified by a different multicolored reflector. Each camera is connected to a processor such as an SGI Indy, so that one Indy takes the x-axis and one the y-axis. Picture recognition software localizes the bumper cars by means of their respective reflectors. Position data on all bumper cars is transmitted 30 times per second (i.e. 30 HZ) to a graphic processor. Thus, the motion of the bumper cars can be ascertained in space and time.
