摘要
车载LiDAR系统具有能快速测定道路、随时上路施测及费用较低等优势,其测距精度可达5mm,综合测点精度达到厘米级,系统采用了先进的直接惯导辅助定位技术(DIA),有效解决了GPS信号失锁的问题。通过电网GIS空间信息服务平台配网数据采集工作的验证,证明在城区电力专题数据采集过程中,车载LiDAR系统能够及时满足相关规范的要求。
The vehicle LiDAR system has advantages of rapid distance measure, low cost and high precision with error less than five millimeters, and solve the issue of GPS signal lock-lose using the advanced direct inertial navigation aided positioning technology. The practical application results show that the system can meet the need of related specifications in time during the data collection process of certain subjects.
