机载LiDAR系统定位方程、误差分析与精度评定

Positioning equation error analysis and precision evaluation for airborne LiDAR system

本文从机载LiDAR系统几何定位方程出发、基于误差传播规律推导了机载LiDAR系统的综合误差计算公式,分别研究了IMU测角、GPS、激光测距、扫描角等多种误差源对激光脚点定位精度的影响规律,从理论上分析了机载LiDAR系统定位精度。本文的结果对实际应用具有重要的参考价值。

From the position equation of airborne LiDAR system, the error source, such as the IMU measures error, the GPS position error, the laser distance measurement error, the laser scan angle error and so on, were discussed detailedly based on the error propagation law in the paper. The influence rule of those errors were studied, and the academic position precision were discussed, The simulation computation indicated that the results could he a good reference to practical application.
