Method for vision detection on body position of athlete during climbing

The invention provides a method for vision detection on the body position of an athlete during climbing. The method comprises steps of S1, athlete characteristic point extraction; S2, actual coordinate extraction; and S3, athlete body position expression. According to the method, a center-of-gravity characteristic point of the athlete is extracted from images, a movement distance of the center-of-gravity characteristic point is measured, the time is recorded, a movement speed of the athlete among climbing walls can be reckoned, and analysis on movement locus of the climbing athlete is facilitated. 本发明提供的种运动员攀岩中身体位置视觉检测的方法，所述方法包括以下步骤：S1：运动员特征点的提取；S2：实际坐标的提取；S3：运动员身体位置的表达；通过图像上提取出运动员的重心特征点，通过测量重心特征点的移动距离并记录时间，便可以推算出攀岩运动员的在攀岩壁之间的移动速度；有助于分析攀岩运动员的运动轨迹。
