| 摘 要： | 安置误差是影响移动测量系统激光点云精度的主要因素之一。当激光点云中存在特征平面时,安置误差会导致该平面与真实平面之间产生较大的偏差,如果存在多个空间上位置关系较好的特征平面,就能够全面反映出系统的安置误差。本文以此为依据,给出了一种基于已知特征平面的移动测量系统安置参数检校方法,并详细阐述了检校场的布设、数据获取及处理等内容。实验证明,该方法是一种简单、可靠的检校方法,具有较高的实用性。

| Abstract: | Bore-sight error is one of the main factors affecting the accuracy of laser point clouds by the mobile mapping system(MMS).When there is a planar feature in the laser point clouds,the bore-sight error will cause a large deviation between this plane and the real plane.If there are multiple planar features with good spatial positional relationship,the bore-sight error of MMS can be fully reflected.Based on this theory,this paper presents a calibration method for estimating the bore-sight error of MMS based on known planar features based,and the layout of calibration field,data acquisition and processing are described in detail.The experiment proves that the method is a simple and reliable method for calibration and has high practicability. |
