Problems solved by technology
First of all, it solves the technical problem that the existing test method cannot see the movement trajectory of the athlete in real time; secondly, this method does not need to place detection equipment on the exercise route or carry other media on the athlete, which reduces the impact of external factors on the athlete. Interference generated

The invention discloses a method utilizing a laser radar device for detecting exercise time and a route track of an exerciser. According to the invention, a detection field is selected and a detectionsystem is established. The detection system includes a detection unit, a judgment timing unit, a track generating unit and a display unit. The detection unit is connected with the judgment timing unit. The judgment timing unit is connected with the track generating unit and the display unit. The motion track generating unit is connected with the display unit. The detection unit includes at leastone laser radar device. The method can record a time value of the exercises passing each segment or the whole course of a route and generate the exercise route track. No other detection and recordingequipment are required to install on the exercise route and the exerciser does not carry any medium, so that no interference is caused to the exerciser. Devices involved in the invention are insusceptible to external environment and are simple in structure and easy to operate.
Description
technical field [0001] The invention relates to a method for detecting the movement time and route trajectory of an athlete, in particular to a method for detecting the movement time and route trajectory of an athlete by using laser radar. Background technique [0002] The time for athletes to complete the exercise according to the prescribed route is a commonly used evaluation index in sports activities such as physical examinations, physical fitness tests, and sports competitions. The evaluation results are obtained by comparing the numerical values, which provide a reference for physical health evaluation, physical training, and sports competition rankings. [0003] The current detection technologies include: sportsman blocking node infrared technology, camera capturing sportsman passing node time technology. At present, there is no method that can detect and record the time value and route track of the athlete's movement through each section and the whole route, and the...
