(For the track and field middle and long distance running, dozens of athletes compete on a 400-meter track, and the levels are mixed. It has always been a big problem to accurately record the number of laps each athlete has traveled. In addition to consuming a lot of manpower and material resources, it is inevitable that there will be human errors, which will affect the accuracy of the results. However, the non-repeatability of track and field competition has determined that athletes cannot be rematched due to the mistakes of the referees (for example, in the track and field competition of the second National Games, one lap is lost for 10,000 meters, and the 10,000 meters of this Games have no results) , Therefore, it has high requirements for accuracy and reliability, especially high-tech competition electronic equipment - automatic lap counting equipment, which is combined with automatic electronic video timing equipment at the end to accurately interpret the ranking and results of athletes. Make sure the competition is open, fair, and fair. The same is true for venue cycling, short track speed skating, etc.
