【摘要】：針對目前商業(yè)激光雷達系統(tǒng)僅適用于低空測繪的不足,開展了面向中高空應(yīng)用的新體制激光雷達的技術(shù)研究。結(jié)合我國新體制中高空激光雷達系統(tǒng)的研制,構(gòu)建了系統(tǒng)的定位模型;針對18km航高激光雷達測圖的定位精度要求,對各項誤差因素進行了定量分析,并開展了系統(tǒng)的參數(shù)設(shè)計與仿真論證,對誤差項進行了分配,給出了量化的參數(shù)設(shè)計結(jié)果。該研究為中高空激光雷達系統(tǒng)的總體設(shè)計及各分系統(tǒng)的指標(biāo)分配提供了定量計算及決策依據(jù)。
[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.
