体育比赛终点运动图像数字处理技术的研究

在竞技体育比赛中,运动成绩的确认,靠已往的手工计时无法满足要求,根据国际田联的规定,大型体育赛会都要求采用电动终点计时系统.目前,国内的研制水平仍然停留在黑白图像判定水平上,本文将高速彩色线阵CCD技术应用于径赛终点电动计时系统,对彩色图像采集后期处理中影响图像质量的各种因素进行了深入地分析,详尽描述了在数字图像处理中如何运用灰度、彩色平衡、直方图均衡化等数字图像处理技术,得到清晰的、高质量的彩色图像数据.

RESEARCH OF THE TERMINAL TIMER SYSTEM IN SPORTS BASED ON THE IMAGE DIGITAL PROCESSING TECHNOLOGY

In sport games,confirming the scores by former handicraft can't satisfy the request.According to the provision of the IAAF(International Amateur Athletic Federation),all the large athletics expositions request to adopt the electric terminal timer system.At present,the studying level in our country is still staying around the black and white.The article applies the super-speed color linear CCD array technique to terminal timer system.The article proceeds by analyzing every kind of factor which affects the picture quantity in the process of CCD collecting image.Therefore,the article manages digital image processing techniques such as the filtering,colorful equilibrium,histogram equalization and so on,so that we can get color image data with clear and high quantity.
