基于转台的线阵激光雷达地面检校方法研究

Research on Linear Array LiDAR Calibration Based on Rotating Platform

介绍了一种基于转台的线阵激光雷达地面检校方法,该方法通过布设物方检校控制场,使用指示激光器建立激光测距值与物方控制点之间的对应关系并引入激光测距的加/乘常数与外方位元素一并作为检校参数,通过坐标转换列出误差方程式;最后使用最小二乘平差解算所有的检校参数。文中给出了实测数据的实验结果分析及精度评定,验证了本文方法的可行性。

A method of linear array LiDAR calibration based on rotating platform is proposed in this paper.After layout of object control field,two indicative laser sensors are used to find corresponding relationship between the laser ranging and object control points.Error equations are established via coordinate transformation,the addition constant and multiplication constant of LiDAR as well as the exterior orientation parameters are considered.Least squares adjustment is used to solve all the parameters.At last,the experiments and accuracy assessment are presented in this paper,which verified feasibility of the method.
