摘要
本文提出基于车载三维激光测量系统的城市道路竣工测量技术,全面系统地研究车载三维激光测量系统的构成、工作原理及其在道路竣工测量中的应用。试验结果表明,基于车载三维激光测量系统的城市道路竣工测量平面精度可达到11.0cm,高程精度为6.6cm,满足城市道路竣工的精度要求,而作业时间大大减少。
A road as-built drawing surveying method based on Vehicle-Borne 3D Laser Imaging System is proposed. The paper discussed the system components, the basic principle and its application in road final surveying. The experiment results show that the proposed method can achieve 11 cm for the horizontal position and about 6.6 cm for the altitude, and reach the requirement of road as-buih drawing surveying in much less working time.
