In order to improve the effectiveness of pathological diagnosis of sports injury,a method of sports injury motion detail feature extraction based on 3D sensing tracking is proposed. The 3D sensing tracking and recognition method is used to carry out the image acquisition for the sports injury action. The edge contour detection and corner detection of the acquired 3D image are performed to extract the key feature points embodying the sports injury detail features. The deformational displace-ment estimation method for an injured part is used to extract the statistical information characteristics of the sports injury action and estimate the injury degree,and combined with the image block segmentation method to extract the motion detail feature of sports injury. The simulation results show that the method,used to perform the motion detail feature extraction and 3D sensing tracking recognition of sports injury,has high feature expression ability for sports injury motion image,and can realize the visu-al pathological diagnosis and treatment for sports injury.%为了提高运动损伤病理诊断有效性,提出基于三维传感跟踪的运动损伤动作细节特征提取方法.采用三维传感跟踪识别方法进行运动损伤动作的图像采集,对采集的三维图像进行边缘轮廓检测和角点检测,提取反应运动损伤细节特征的关键特征点,采用损伤部位的形变位移估计方法实现运动损伤动作的统计信息特征提取和损伤程度评估,结合图像的块分割方法实现运动损伤动作细节特征提取.仿真结果表明,采用该方法进行运动损伤动作细节特征提取和三维传感跟踪识别,对运动损伤动作图像的特征表达能力较好,实现可视化的运动损伤病理诊断和治疗.
