摘　　要：运动过程中,受自身动作和其他外界因素的影响,容易出现运动损伤姿态,因此,提出传统方法采集数据。但传统采集方法规划的采集路径不是最优,导致提取的特征数据与真实动作不匹配,因此,研究激光三维图像,对运动损伤姿态的全新采集方法。该方法以三类百分位假人模型为参照,建立运动姿态三维扫描模型;通过规划激光扫描路径,捕捉整体运动姿态;使用平滑度参数,提取三维图像点云特征;根据径向函数,采集并生成完整的运动损伤姿态。实验结果表明:与传统方法相比,此次研究方法得到的姿态轨迹,与真实运动损伤姿态的运动轨迹更加匹配。可见激光三维图像,更加适用于采集运动损伤姿态。In the process of sports,affected by their own actions and other external factors,it is easy to appear sports injury posture,so the traditional method is proposed to collect data.However,the traditional acquisition method planning is not the optimal acquisition path,resulting in the extracted feature data and the real action does not match,so the research of laser 3D image,a new acquisition method of motion injury posture.In this method,three kinds of percentile dummy models are used as reference to establish the 3D scanning model of motion posture;the laser scanning path is planned to capture the overall motion posture;the smoothness parameter is used to extract the 3D image point cloud features;according to the radial function,the complete motion damage posture is collected and generated.The experimental results show that:compared with the traditional method,the attitude trajectory obtained by this research method is more consistent with the motion trajectory of real motion injury posture.Laser 3D image is more suitable for the acquisition of motion injury posture.
