摘要

机载激光雷达三维成像技术中对工作参数的设置非常重要，其关系到机载激光雷达测量精度的高低。为了获得机载激光雷达工作参数的最优设置值，推导了机载激光雷达扫描激光脚点的三维坐标误差，进行了误差因素分析，并确定了影响机载激光雷达激光脚点测量精度的各个工作参数。基于正交化实验设计，对每个工作参数设置了3个水平，共获得了18个机载激光雷达工作参数组；通过仿真机载激光雷达扫描过程，获得了在18组参数设置值下扫描激光脚点的三维坐标误差。通过正交实验误差分析，获得了各工作参数的最优设置值，并探讨了各工作参数的取值特点和规律，为提高机载激光雷达的实际测量精度提供了理论指导。

Abstract

It is very important to select reasonable values of various operating parameters of airborne laser imaging radar (LIDAR), which are closely related to the measurement accuracy of airborne LIDAR. In order to obtain reasonable configuration values of various operating parameters, the three-dimensional (3D) coordinate errors of laser footprints from airborne LIDAR are deduced, and error factors and operating parameters affecting the positioning accuracy of the laser footprints are determined. Then, based on orthogonal experimental design, three levels of configuration values of various operating parameters are selected, respectively, and by cross combination, eighteen orthogonal experiments are designed. For each of the eighteen orthogonal experiments with different levels of configuration values of the operating parameters, the airborne laser scanning procedure are simulated, respectively, and the corresponding 3D coordinate errors of the laser footprints are calculated. By orthogonal experimental error analysis, the optimal configuration values of the operating parameters are obtained. Furthermore, the configuration characteristics and laws of various operating parameters are analyzed, which provide a theoretical guidance for improving the measurement accuracy of airborne LIDAR.
