摘要当下国内外体育竞赛在记圈方面仍是依靠人力解决的多，在不断技术化信息化社会大势下能够用机器自动实现这一功能才是顺应趋势的，我们基于光电检测方法及利用Matlab还有远程射频识别技术，结合国际田径联合会的相关要求以及现场实况设计一个整体可用地系统，其中软件部分的识别部分很是关键。27276
这篇论文突出的重点是如何用软件设计法把运动员身份辨识出来并准确记录剩余圈数，更进一步应该还能显示结果并进行信息管理和更新。在图像需要预处理时候用了适当灰度化还有canny算子参与的边缘测试，再分离字符并且用形态法从数学方面确定这个位置。分离数字字符用了以二值法再经过垂直投影分析才把数字分离出来再记录进相应系统来识别，本文也针对这一部分进行了详细说明。

Title Method of automatic lap marathon record
Abstract
The current domestic and international sports competitions in mind circles are still relying on human settlement and more technology in the continuous trend of the information society can achieve this function by the machine，and based on photoelectric detection method and use Matlab there the agency frequently remote identification technology,combined with the relevant requirements of the International Association of Athletics Federations and live design available to the system as a whole including the identification part of the software part of it is the key.
This paper focuses on how prominent software design method to identify the athlete out of the identity and accurately record the number of laps remaining and further should be able to show results and information management and updates. In the image pre-processing time required by the appropriate graying also canny operator participation edge test, then the level of analysis and to determine the position of the separation of characters from the mathematics used Morphology. Separate numeric characters with the binary method to go through the vertical projection analysis only then re-recorded digital separated into the appropriate system to identify, we have for this section are discussed in detail.
