摘要
车载激光扫描技术在进行作业时需要架设基站进行后处理差分解算,且只能在基站一定范围内进行采集,局限性很大。针对这一情况,本文提出了一种免基站扫描技术,采用加装RTK模块,利用轨迹固定解点位对单点定位轨迹进行后处理修正,很好地解决了精度问题。此方式免去了架设基站产生的人力时间成本,扫描效率提高了50%,人力成本减少了一半,且可自由规划扫描,进一步优化了车载移动扫描用于质检工作的方案,提高了质检效率。试验结果表明,该方案精度与架设基站方案相当,扫描效率大大提高。
Vehicle laser scanning technology in poor operation need to set up the base stations post-processing decomposition,and can only be carried out within a certain range in the base station to collect,limitation is very big,in order to solve this situation,this paper proposes a free base station scanning technology,by adding RTK module,using the tracks of fixed point of single point positioning solution to correct the post-processing,and very good solve the problem of the accuracy,This method eliminates the labor time cost caused by the erection of base station,Improved scanning efficiency by half,reduced staffing costs by half,and the scanning can be planned freely,which further optimizes the scheme of vehicle-mounted mobile scanning for the inspection work,and improves the inspection efficiency.The test results show that the accuracy of this scheme is comparable to that of the base station erection scheme,and the scanning efficiency is greatly improved.
