本段代码是基于opencv识别灯的一个小程序，在拍摄的视频内，实时的识别灯的位置，并用圆圈圈出来。-This code is based on a small program opencv identification lights, shooting video in the position of real-time identification of the lamp, and it circled.

能识别多张图片中圆形轮廓的形状，可以快速识别比一般的Hough 圆检测快。(Recognizes the shape of a circular outline in multiple pictures to quickly identify faster detection than the average Hough circle.)
