摘要
机载LiDAR为复杂的多传感器集成系统,系统误差是影响LiDAR定位精度的主要误差源.本文基于LiDAR定位方程,模拟往返航飞轨迹和激光脚点数据,定量地引入安置平移和安置旋转误差,研究各个系统误差对定位精度的影响程度和规律.实验结果表明安置平移误差对激光脚点定位精度的影响在对应方向有等量影响,而安置旋转误差对定位精度的影响在对应方向与扫描角相关.
Airborne LiDAR is multi-sensor system.Systematic error is a main error which affects LiDAR positioning accuracy.This paper simulates flight trajectory and laser footprints based on LiDAR positio-ning equation.Boresight errors are introduced to analyze the relationship between LiDAR systematic error and positioning accuracy.Results show that lever arm biases have the same impact on the accuracy of la-ser footprint while boresight angle biases have relationship with scanning angles on the positioning accura-cy.
