一种自动判断运动员踩线的方法、系统及存储介质
By constructing a Cartesian coordinate system and a human key point detection algorithm, the system automatically determines whether an athlete has stepped on the line and provides a warning when the line is stepped on, thus solving the problem of lack of automatic judgment in existing technologies and improving the athlete's test pass rate.

AI Technical Summary
Current technology lacks a method to automatically determine whether athletes have stepped on the line, leading to athletes developing a habit of stepping on the line during practice, which affects the pass rate in formal tests.
By acquiring real-time video frames from the preparation area, a Cartesian coordinate system is constructed, the equation of the starting line segment is calculated, the coordinates of key points on the ankle and knee are extracted using a human key point detection algorithm, the coordinates of the toe are calculated and compared with the equation of the line, it is determined whether the athlete has stepped on the line, and the athlete is alerted if the line is stepped on.
It has enabled the automatic detection of athletes stepping on the line, helping athletes develop good habits and improving the pass rate of the test.
