国产机载LiDAR系统安置角误差检校方案研究

Domestic Airborne LiDAR System Angle Error Calibration Plan Research

机载激光扫描仪(Light Detection And Ranging,LiDAR)系统是由多个子系统集成,其中,安置角误差是集成误差中最大的误差源,安置角误差检校的方法多种多样,高效率、高精度的检校方式还需要试验的支撑。本文对平差模型法和几何模型法进行了试验分析,试验结果很好地证明了不同方法的优越性,为机载LiDAR系统的安置角检校提供了参考。

Airborne laser scanner system（ Light Detection And Ranging,LiDAR） is consists of several subsystems,which misalignment error is the largest source of error in the integrated error,the calibration methods is varied,the calibration way with high efficiency and high precision calibration needs the support of test. In this paper,the adjustment model and geometric model method were tested and analyzed. The experiments showed the advantages of different methods,provides the reference for the setting angle calibration of airborne LiDAR system.
