摘　　要：针对传统人体运动姿态相似性度量方法计算准确率低的问题,提出一种基于激光热成像的人体运动相似性度量方法。首先提取人体热成像数据,使用热像仪测温形成人体热成像图,在热成像图中选取不同的数据采样点,得到对应关节的人体静止姿态数据,不断调整关节点数据形成人体运动姿态,使用欧拉角的旋转矩阵处理得到人体姿态捕捉区域,定义传感节点计算得出运动姿态向量,使用马氏距离处理运动姿态向量,得到人体运动相似性度量表达式。实验结果表明:与2种传统人体运动姿态相似性度量方法相比,基于激光热成像的人体运动姿态相似性度量方法计算准确率为92%,准确率更高,更适合计算人体运动相似性度量。Aiming at the low accuracy of traditional human motion attitude similarity measurement method,a human motion similarity measurement method based on laser thermal imaging is proposed.Firstly,the thermal imaging data of human body are extracted,and the thermal imaging image is formed by using thermal imager to measure temperature.Different data sampling points are selected in thermal imaging image to obtain the static posture data of the corresponding joints.The motion posture of human body is formed by constantly adjusting the data of the joints,and the human posture is captured by processing the rotation matrix of Euler angle.In the region,the motion attitude vectors are calculated by defining sensor nodes,and the motion attitude vectors are processed by Mahalanobis distance,and the expression of human motion similarity is obtained.The experimental results show that,compared with the two traditional methods of human motion attitude similarity measurement,the method based on laser thermal imaging has a higher accuracy rate of 92%,which is more suitable for calculating human motion similarity measurement.
