摘要:

为了实现工业自动化检测,采用机器人技术与线结构光扫描技术两者相结合,将线结构光传感器安装在机器人法兰盘上,由于安装误差等的存在,影响到扫描系统的测量精度。针对这一问题,文中利用改进ICP算法的点云配准技术,对点云进行配准,反求由安装误差造成的变换矩阵,实现对系统误差的校准。实验结果表明,文中所提方法达到了较好的校准效果。

Abstract:

In order to realize the detection of industrial automation, the technology of robot and line structure light scanning technology is combined, the line structure light sensor installed on the robot flange, because the installation error exists, affect the measurement accuracy of the scanning system. To solve this problem, by using the improved ICP algorithm of point cloud registration technology in this paper, the registration of point cloud, the reverse transformation matrix caused by installation error, the calibration of the system error. The experimental results show that the proposed method achieves better calibration.

Key words: the improved ICP algorithm; , point cloud registration; , the installation error calibration
