【摘要】 基于条纹原理的阵列探测体制激光成像雷达由于其独特的技术优势在激光测绘中具有潜在的应用。本文介绍了"扫帚"扫描结合条纹原理阵列探测体制激光雷达的仿真及飞行实验研究结果。首先介绍了新体制激光雷达仿真平台的建立及典型的仿真结果。利用该仿真平台可指导新体制激光雷达的设计,并对机载飞行实验参数的设定进行成像效果仿真。最后开展了新体制激光雷达机载飞行实验,给出了典型地区的原始条纹图像及经过数据处理后的点云图。通过与实际被动光学相机成像图像进行比较,验证了新体制激光雷达在航空测绘等方面的技术可行性。更多还原

【Abstract】 Li DAR is a potential technology in mapping field. Especially, the Li DAR systems applying streak tube have attracted great attention recently due to their special properties about detection sensitivity and distance resolution. This article describes the simulation of the stripe principle array Li DAR system with "broom" scanning and the results of the flight experiment. Firstly, the establishment of the new Li DAR simulation platform and the typical simulation results are introduced. The simulation platform can guide the design of the new Li DAR, and simulate the setting of the airborne flight experiment parameters. Finally, the airborne flight experiment of the new Li DAR is carried out, then original streak images of the typical area and the cloud points of the images are given. Compared with the images of the passive optical camera, the technical feasibility of the new Li DAR in aerial mapping is verified.更多还原
