Description: DIY基于摄像头的激光测距仪,介绍一下工作原理。一束激光被投射到目标物上，并在摄像头上被显示。激光束被认为是理想的平行于摄像头的中心光轴。激光点由摄像头的其余部分所捕获。一个简单的计算就是寻找最亮点。如果设激光点就是这个场景的最亮点（似乎在室内我的激光发射器确实是最亮的），那么这个点的位置在图帧中的位置是确定的。然后我们只需要计算这个点在沿着y轴的距离，就能计算出目标物离摄像头的距离，激光点距离中心越近，离目标物越远。-DIY-based laser rangefinder camera, tell us about the working principle. A bouquet of laser was projected onto the target, and be displayed in the camera head. Laser beam is considered an ideal parallel to the central axis camera. Laser point from the rest of the camera caught. A simple calculation is to find the most highlights. If the laser point is the highlight of this scene (it seems that I am in indoor laser transmitter is the brightest), then the points in the frame diagram of the location is determined. Then we only need to calculate the points along the y-axis distance, we can calculate the target s distance from the camera, laser distance centers closer, farther away from the target.
