基于人体姿态视觉判断的立定跳远成绩测量方法

Measuring method of standing long jump result based on visual judgment of human body posture

为减少人力、物力成本,快速精确地测量出运动员的立定跳远成绩,设计了一种基于人体姿态视觉判断的立定跳远成绩测量方法。首先检测人体姿态,使用改进的姿态跟踪策略跟踪运动员姿态,分析躯干、腿、脚部关键点信息,判断运动员所处的跳远状态;然后通过背景差分、小波变换等技术精确定位落地点后边缘点;最终通过逆透视变换精确计算出运动员的立定跳远成绩。经过多次实验,测量的立定跳远成绩的平均绝对误差为0.507 cm,基本满足立定跳远考试成绩测量1 cm的精度要求。

In order to reduce the cost of manpower and material resources,and measure the standing long jump result quickly and accurately,a method of measuring the standing long jump result based on the visual judgment of human body posture was designed.Body posture was detected firstly,and the posture of the athlete was tracked by the improved posture tracking strategy.The torso,legs,feet point information was analyzed to judge the athlete’state of long jump.Then,the rear edge of the landing site was pinpointed through the background difference method,wavelet transform technology and so on.Finally,the standing long jump results of athlete were calculated accurately through the inverse perspective transformation.After many experiments,the average absolute error of the measured standing long jump results was 0.507 cm,which basically met the measuring accuracy requirement of 1 cm in the standing long jump test.
