如何用摄像头来测距（opencv）
在摄像头下面固定一个激光笔，就构成了这个简易的测距装置。看一下图吧。
原 理
假设激光束是与摄像头的光轴完全平行，激光束的中心落点在在摄像头的视域中是最亮的点
Ranging (opencv) how to use the cameras to fixed camera following a laser pointer, constitute a simple ranging devices. Look at the drawing. Postulates that the laser beam is perfectly parallel with the optical axis of the camera, the center of the laser beam placement is the brightest point in the camera' s field of view (2013-02-23, C/C++, 7KB, 下载90次)
