新型测绘技术在道路竣工规划验收测量中的应用研究

Research on the application of new surveying and mapping technologies in the road final acceptance survey

将地面三维激光扫描、背包式移动扫描、无人机倾斜摄影测量三种新型测绘技术应用到道路竣工规划验收测量中,通过数据采集实验验证精度和效率。结果表明,三种测绘技术在平面点位精度和高程精度上均优于5 cm,能满足道路竣工规划验收测量的要求,且作业效率较传统方法优势明显。其中,背包式移动扫描精度可靠、作业效率高,综合表现最好。

This paper studies three kinds of new surveying and mapping technologies—terrestrial 3D laser scanning,backpack-mounted 3D mobile scanning and unmanned aerial vehicle(UAV)oblique photogrammetry.These methods are applied to the road final acceptance survey.The accuracy and efficiency are verified by the data acquisition method.The results show that the accuracies of the three kinds of equipment are superior to±5 cm in horizontal and vertical direction which can fulfill the requirement of the road final acceptance survey.Meanwhile compared to the traditional method,the survey efficiency is significantly improved.Among them,backpack-mounted 3D mobile scanning has reliable accuracy and high efficiency which is the best performance.
