Abstract: As a high-precision measuring device, the optical motion capture system can be used to obtain three-dimensional position information of a target in space. Accuracy is one of the most important indicators of a motion capture system. In order to study the positioning accuracy results of NOKOV optical motion capture system, this paper proposes a performance evaluation method which includes static and dynamic results evaluation. Absolute accuracy and repetition accuracy testing are carried out respectively to verify the accuracy index of NOKOV motion capture system. The experimental results show that the measurement accuracy of NOKOV motion capture system meets the requirements of main application scenarios.
Keywords: NOKOV; motion capture; accuracy test; repetition accuracy; absolute accuracy
