摘要
首先介绍了激光和CCD的外部标定算法,并对该算法进行了改进,提高了标定的精确度。然后提出了一种新的激光点云分割方法,即将点云标定到CCD图像上,通过图像分割的方法实现了快速准确提取感兴趣目标区域内的点云。
The algorithm of the extrinsic calibration of laser rangefinder and CCD camera is introduced in this paper firstly.Secondly,an improved algorithm of the extrinsic calibration of laser rangefinder and CCD camera is presented.The higher calibration precision is got in the improved algorithm.Thirdly,a new method for segmentation point cloud by mapping the point cloud to the CCD image is proposed in the paper.By the new method,the point cloud belong to ROI regions is extracted rapidly and exactly through images...
