摘要: 仿真方法是应急管理的重要研究手段,仿真研究对真实场景的数据采集提出了需求。以无人机为载体、搭载激光雷达、惯性测量单元等硬件设备,集成设计了机载点云数据采集平台。利用该平台采集实际场景点云数据,使用SLAM方法实时建立点云地图,对点云地图进行三维重建。解决了真实场景三维模型的构建问题,设计并实现了一个点云处理和三维建模软件,最后通过实验对算法与软件进行了有效性和稳定性验证。

Abstract: Simulation is a significant method of emergency management research which demands the digital data of real scenes. Hardware was integrated to design the air borne point cloud data acquisition platform by using UAV as carrier, picking up the laser radar, IMU, etc. Furthermore, the platform was used to collect point cloud data and SLAM algorithm was used to establish real-time point cloud map. Moreover, point cloud map was utilized to establish 3D model. The problem of real scene 3D model construction was solved, designing and realizing point cloud processing and 3D modeling software, and a lot of experiments were carried out to verify the algorithm and software.

Key words: Unmanned Aerial Vehicle, 3D LIDAR, SLAM, three-dimensional reconstruction, point cloud processing software
