【摘要】：利用二维激光雷达以及转轴搭建的快速三维扫描系统由于雷达光心点与系统转轴中心通常不重合,因此需要进行系统的标定。本文基于LMS500二维激光雷达搭建了一套三维激光扫描系统,在分析了核心部件LMS500激光传感器测量误差的基础上,采用一种简单易行的方法完成了三维系统主要参数的标定,获得了扫描系统的数据转换公式。最后进行了阶梯轴零件的扫描并获得了较好的实验结果。
[Abstract]:A fast 3D scanning system based on two dimensional lidar and rotating axis is constructed because the center of the radar light does not coincide with the center of the rotating axis of the system, so it is necessary to calibrate the system.In this paper, a 3D laser scanning system based on LMS500 two-dimensional laser radar is built. Based on the analysis of the measurement error of the core component of the LMS500 laser sensor, the calibration of the main parameters of the 3D system is accomplished by a simple and feasible method.The data conversion formula of the scanning system is obtained.Finally, the step shaft parts are scanned and good experimental results are obtained.
