Research on the Technology of Two Kinds of Data Sources Coupling Processing and 3D modeling

针对如何将无人机倾斜摄影技术测量和三维激光点云这两种不同数据可以有效的耦合在一起,解决二者在空间上的耦合这一问题开展研究,采用点云实体融合的方法实现无人机倾斜摄影影像和地面激光点云的融合。实现点云融合的关键,是要解决地面激光点云与无人机倾斜影像自动高精度配准、地面激光点云与无人机倾斜影像点云的去冗和融合问题。主要解决如何将无人机倾斜摄影测量数据和三维激光测量点云数据的高效耦合,并对耦合结果实现三维模型构建的实验验证。构建三维模型是所有作战模拟、作战仿真、装备虚拟训练等的基础,本研究为获取战场信息、构建形象直观、易于理解的三维战场态势图模型,以提高指挥员对战场理解的准确程度、辅助指挥决策等,具有重要的军事意义。

This paper aims at the effective coupling of uav tilt photogrammetry and 3D laser point cloud data,so as to solve the problem of their coupling in space.The point cloud entity fusion method is adopted to realize the fusion of UAV tilt photographic image and ground laser point cloud.The key to realize point cloud fusion is to solve the problems of automatic high-precision registration of ground laser point cloud and uav tilt image,de-redundancy and fusion of ground laser point cloud and UAV tilt image point cloud.It mainly solves the problem of how to combine the tilt photogrammetric data of UAV with the 3D laser point cloud data effectively,and realizes the experimental verification of 3d model construction on the coupling results.The construction of 3D model is the basis of all combat simulation,combat simulation and equipment virtual training,etc.This study is of great military significance for obtaining battlefield information,building an intuitive and easy-tounderstand 3D battlefield situation diagram model,so as to improve the accuracy of commanders'understanding of the battlefield and assist command decision-making.
