【摘要】：针对目前商业激光雷达系统仅适用于低空测绘的不足,开展了面向中高空应用的新体制激光雷达的技术研究。结合我国新体制中高空激光雷达系统的研制,构建了系统的定位模型;针对18km航高激光雷达测图的定位精度要求,对各项误差因素进行了定量分析,并开展了系统的参数设计与仿真论证,对误差项进行了分配,给出了量化的参数设计结果。该研究为中高空激光雷达系统的总体设计及各分系统的指标分配提供了定量计算及决策依据。
[Abstract]:Aiming at the deficiency that the commercial lidar system is only suitable for low altitude mapping at present, a new system lidar technology for medium and high altitude applications is studied in this paper. Combined with the development of the new system of medium-high altitude lidar in China, the positioning model of the system is constructed, and the error factors are quantitatively analyzed according to the positioning accuracy requirements of 18km aerial high-altitude lidar mapping. The parameter design and simulation of the system are carried out, the error term is allocated, and the quantitative parameter design results are given. The research provides a quantitative calculation and decision basis for the overall design of the medium-high altitude lidar system and the allocation of indexes for each subsystem.
