作为一项典型的体育运动,立定跳远动作实现简单,测试环境要求低,常作为体育测试的必考科目.传统的人工测量方法效率不高.本文提出一种新的立定跳远成绩自动评判装置,通过红外线扫描的方式来定位运动员最终落地位置以算出跳远成绩.系统将一定数量的红外对管分组,分别进行粗扫和精扫分级式扫描,实现快速、精确定位,兼顾了测量速度和精度的要求.

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 auto?matically. 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 curso?ry scanning with precise scanning for fast and accurate positioning,taking into account the measurement speed as well as accuracy requirements.
