针对非接触式动态位姿测量系统在人体运动信息检测的应用中对人体精细、微小动作测量精度的要求,提出了非接触式动态位姿测量系统的重构修正模型.该模型以三维重构理论知识为基础,综合考虑影响测量系统精度的多种因素,给出了测量误差理论体系,确定了该模型的修正成像方程.实验表明:通过基于修正模型的非接触式动态位姿测量系统进行静态标定和动态位姿参数测量,测量精度比修正前有明显提高.

To meet the requirements for measurement accuracy in analyzing human fine and small motions in the application of contactless dynamic measuring system detecting human motion information,a＇ reconstruction modified model for this system was proposed. Based on the theory of three-dimensional reconstruction and all kinds of factors affecting the measurement accuracy, the theoretical system of measurement error and the modified imaging equations were established. The experimental results show that the measurement precision of the modified system is sharply improved comparing with the measurement accuracy of non-modified system in ,static calibration and dynamic posture measurement with the system.
