激光测距系统设计与标定实验

Design and Calibration Experiment of Laser Ranging System

在分析激光三角法测距的工作原理的基础,三角法测距原理设计了激光测距系统。通过设计实验装置和优化相机与激光器之间的相对安装位置和安装角度,提高系统的精度,减小装置的体积。对系统进行标定,建立激光条纹像素坐标与空间三维坐标之间的关系。为检验系统的性能,对实物进行测量实验。实验结果表明,测量误差不大于2 mm,可满足机器人对目标定位的要求。

A laser ranging system is designed based on the principle of triangular ranging.Analyzed the working principle of rigonometric rangingr ranging.The accuracy of the system is improved and the volume of the device is reduced by experiment and comparison of setting the relative installation position and installation angle the between the camera and the laser.The system is calibrated,The relationship between the pixel coordinates of the laser stripe and the spatial three-dimensional coordinates is established.Measurement experiments is conducted on real objects to verify the performance of the system,The measurement error is not more than 2mm,which can meet the requirements of the robot for target positioning.
