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。The positions of radar center and revolving axis center usually misalign in rapid 3 D scanning system,so the system must be calibrated. A 3 D laser scanning system based on LMS500 2 D laser radar is established. Measuring error of LMS500 laser sensor was analyzed,and the main parameters of 3 D scanning system were calibrated. Data conversion formula of the system was obtained. The component with stepped shaft is scanned by using the system,and the good experimental results are gotten.
