针对三级跳远运动的角度指标,利用OpenCV计算机视觉开发平台,提出了角点角度值计算的新算法,对三级跳远视频中运动员的着地角、起跳角和膝关节角进行定位及计算,并尝试对中外八名运动员的角度数值进行分析。实验结果表明,该方法可以较精确的进行角点定位,定量计算三级跳远运动员的角度指标,并可依据数据对不同运动员的角度指标进行对比分析,对三级跳远训练有一定的指导意义。

In view of the triple jump movement angle index, a new algorithm for calculating the angle value is proposed by using the OpenCV computer vision development platform, and the grounding angle, the take-off angle and the knee joint angle of the athletes in the triple jump video are located and calculated. This paper tries to analyze the angle values of eight Chinese and foreign athletes. The experimental results show that the method can accurately locate the corner points, quantitatively calculate the angle index of the three-level long jump athletes, and compare and analyze the angle indicators of different athletes according to the data, which has certain guiding significance for the three-level long jump training.
