Abstract

This paper presents a monocular PSD-based motion capture system and CCD camera based system. The first system includes a PSD (Position Sensitive Detector) and active infrared (IR) LED markers that are placed on the object to be tracked. The PSD sensor is placed in the focal plane of a wide-angle lens. The microcontroller calculates the 3D position of the markers using only the measured intensity and the 2D position on the PSD. The second system includes two CCD camera and LED markers that are in hand and draw any motion trace. From the experimental results we see that the two kinds of methods for acquiring 3d data will be compare in accuracy, speed, process, methods, experimental circumstance.
