车载三维激光扫描系统外参数标定研究

Research of Calibrating Vehicle Laser Scanner's External Parameters

车载三维激光扫描技术是近年来兴起的获取三维空间信息的重要手段,具有速度快、成本低等特点。车载激光扫描系统主要由激光扫描仪、全球定位系统和惯性导航系统组成。车载激光扫描系统中存在多种误差,本文对系统中的安置误差进行了介绍,对该误差提出了一种通过面寻找同名点检校的方法,并给出了检校流程,最后通过比较特征点坐标来检验检校的结果。

Vehicle-borne 3DLaser Imaging technology is an important measure to get the three-dimensional spatial information with high speed and low cost in recent years.Vehicle-borne 3DLaser Imaging system consists of laser scanner,GPS and inertial navigation system.There are many errors in Vehicle-borne 3DLaser Imaging system,this paper introduced the system placement error,and calibration the error with point of the same name which get through surface,and gives calibration process,finally verification results of the calibration through comparison object feature point coordinates.
