A Study on the Sensor Calibration for Low Cost Motion Capture Sensor using PSD Sensor

PSD센서를 이용한 모션캡쳐 시스템의 센서보정에 관한 연구

In this paper, we deal with a calibration method for low cost motion capture sensor using PSD (Position Sensitive Detection). The PSD sensor is employed to measure the direction of incident light from moving markers attached to motion body. To calibrate the PSD optical module, a conventional camera calibration algorithm introduced by Tsai. The 3-dimensional positions of the markers are measured by using stereo camera geometry. From the experimental results, the low cost motion capture sensor can be used in a real time system.
