摘　　要：采用当前方法捕获人体动作时,捕获到的动作数量与人体实际进行的动作数量不符,捕获人体动作所用的时间较长,存在动作捕获率低和捕获耗时少的问题。将红外激光器应用到人体动作捕获过程中,提出基于红外激光器的人体动作捕获技术,采用红外激光器采集人体的动作信息,通过主分量分析方法对红外激光器采集到的动作信息进行处理,提取出信息中的主要信息。对动作捕获坐标系进行转换,初始化标定人体肢体姿态和标定节点,根据标定结果得到人体坐标系和标定节点之间存在的旋转矩阵,在旋转矩阵的基础上获取变换矩阵,通过变换矩阵得到人体肢体的动作状态和实时位置,完成人体动作的捕获。实验结果表明,所提方法的动作捕获率高、捕获耗时少。When the current method is used to capture human movements,the number of actions captured isn’t constant with the actual number of human movements.It takes a long time to capture human movements,and there are some problems,such as low capture rate and less time consuming.The infrared laser is applied in the process of human body motion capture,and the human body motion capture technology based on infrared laser is put forward.The infrared laser is used to collect the movement information of human body.The action information collected by infrared laser is processed by principal component analysis(PCA),and the main information is extracted.The motion capture coordinate system is transformed to initialize and calibrate the body posture and the calibration node,and according to the calibration results,the rotation matrix existed between the human coordinate system and the calibration node is obtained.The transformation matrix is obtained based on rotation matrix.The motion state and real-time position of the human limbs are obtained by transformation matrix to complete the capture of human body motion.The experimental results show that the proposed method has high capture rate and less capture time.
