摘要
针对摄像机与3D激光测距仪外部标定问题,提出一种以镂空的棋盘格为标定模板的新方法.与传统标定方法不同,整个标定过程一次完成数据采集,根据图像和点云数据提取的角点实现外部标定,同时,仅采用同一块标定模板和一次数据采集完成整个标定过程,解决了以往因标定过程繁琐对标定精度带来影响的问题.实验结果表明,该方法简单实用,效果较好.
This paper provides a novel method based on the calibration panel of hollow checkerboard for the external calibrating of camera and laser range finder. Compared with traditional method, this method needs only one data acquisition, and the external cali- bration by this method can be completed by using the angular points extracting from the image and point cloud data. This method is one of simple process because of one calibration panel and one data acquisition. And the problem of low accuracy because of complex process of the traditional method is avoided. Experimental results show this method is practical and effective.
