基于图像处理的激光测距研究与实现

摘要

In this paper, a feasible ranging system is designed by using laser and CCD camera.A laser pen and a camera was used as the measurement devices and processing the photo generate by the camera by using the open source image processing library OpenCV to find the position of the laser spot in the camera images;and then using the position coordinates information and the range models to find the formula parameters by the using of a few sets of known measurement parameters.As a result, we can establish the function between the position of the laser spot image information with the distance between the laser and the objects to be measurement.Then the goal of the ranging will be achieved.%利用激光光源和CCD相机设计出一套测距系统.采用激光笔和摄像头作为测量设备,利用开源图像处理库OpenCV对摄像头照片进行相关图像处理,找到激光点在摄像头成像照片中的位置;然后利用该位置坐标信息,建立测距模型,通过几组已知的测量参数校正测距公式的参数,建立激光点成像位置信息和物体与测距系统距离之间的函数关系,从而实现测距.
