摘　　要：为了对网球运动员击球动作轨迹线形实施高分辨捕捉,提出一种基于背景差法的网球运动员击球运动轨迹线形捕捉方法.在三维视觉模型下进行网球运动员击球运动轨迹线形图像采集,选用小波变换方法对采集到的运动轨迹线形图像进行滤波处理,同时增强灰度直方图像信息,定位网球运动员击球运动轨迹线形的关键特征点,修正以及调整定位误差,完成精准捕捉轨迹线形.结果表明,所采取得网球运动员击球运动轨迹线形捕捉方法具有较强的可行性,且动作捕捉能力较好.In order to capture the trajectory of tennis players’ hitting motion with high resolution, a method based on background subtraction was proposed to capture the trajectory of tennis players’ hitting motion. Under the three-dimensional visual model, the linear image of tennis players’ hitting trajectory is collected, and the wavelet transform method is used to filter the collected linear image. At the same time, the gray histogram image information is enhanced to locate the key feature points of the tennis player’s trajectory alignment, and the positioning errors are corrected and adjusted to complete the accurate capture of trajectory alignment. The results show that the linear capture method of tennis players’ hitting trajectory is feasible, and the motion capture ability is good.
