基于视频图像处理技术的网球发球最佳击球点预测

Best Hitting Point Prediction of Tennis Serve Based on Video Image Processing Technology

目前,在网球运动中,发球技术是唯一一个不受到对手的限制,一项通过训练就可以自主掌握的关键技术。旨在使用视频图像处理的方法,对日常的网球发球训练进行分析研究。高速摄像机采集发球视频,在运动员发球过程中,通过发球手臂的关节点进行颜色标记,以每一帧图片中标记点的坐标代替关节点坐标。通过研究手臂的运动轨迹,找到了发球过程中的最佳击球点。

At present,the serve technology is the only one not to be restricted by the opponent,which is a key technology can be mastered through training in tennis.The purpose of this paper is to analyze the daily service training of tennis using the method of video image processing.This paper uses the high-speed camera to record tennis serve video and mark with color on the joint service arm,replacing the coordinates of each frame in the picture marked points with articulation point coordinates.By studying the trajectory of the arm,and found the optimal point in the process of serve.
