终点摄像计时判读系统测量误差分析

Research on Measurement Errors in Slit Video Timer

我国将在2008年承办奥运会.终点摄像计时判读系统是奥运会各竞速类项目的核心设备之一,其研究和应用在我国尚处起步阶段.针对国内外各种终点摄像计时判读系统设计使用状况,分析发令传感、计时单元、图像清晰度、曝光准确度、客体与背景、判读技能、瞄准精度及摄像头位置等误差环节,提出了控制误差的对策.

Slit video timer is one of the most important equipments in track and field events. The research and application of the device are still in their beginning stages in China. This paper analyzes the measurement errors of slit video timer based on the research and application of the slit video timer model FP2000. It also describes the way to reduce the errors. The conditions to reach 1 ms measurement precision are discussed.
