Abstract:
As a typical sport，standing long jump action is simple. It requires low test environment and is often listed as a compulsory subject in sporting tests. The conventional measurement method is to observe the distance by the human eye，which usually causes deviations and is thus inefficient. A new device is designed to measure the jump distance automatically. It locates the athlete’s final landing position via infrared in order to calculate the long jump landing scores. A large number of infrared tubes are divided into groups. The program adopts hierarchical scanning which combines cursory scanning with precise scanning for fast and accurate positioning，taking into account the measurement speed as well as accuracy requirements.
