Abstract

Optical motion capture systems have been widely used in biomechanical, medical treatment, uav control and other fields. At present, the accuracy of optical motion system has been studied, but the relationship between the layout of optical camera in the detection area and the detection space boundary and the accuracy stability of the calibration system within the detection space has not been studied. In this paper, the optical motion capture system is composed of 8 Optitrack Prime 13 cameras arranged in a single ring with equal height and equal spacing. According to the size of the detection object, the pitch angle of the camera is adjusted through calculation, and the maximum detection volume is determined. The system is calibrated within the detection volume to upgrade the calibration accuracy. The quantization of the layout data of the optical motion capture system makes the system test data stable and reproducible, and the consistency of the test system parameters is realized.
