摘　　要：利用无人机获取航拍影像生成密集点云,然后基于点云三维建模,通过无人机获取高重叠度影像;利用摄影测量软件PhotoScan对无人机影像处理生成密集点云,再将密集点云导入MicroStation中进行三维建模;最后以某学校实验楼为测试对象,验证了此种建模方法的可行性。This paper uses drones to obtain aerial images to generate dense point clouds,and then based on 3D modeling of point clouds,obtain high-overlap images through drones,and use photogrammetry software PhotoScan to process drone images to generate dense point clouds.The point cloud is imported into the MicroStation for 3D modeling.Finally,taking a school laboratory building as the test object,the feasibility ofthis modeling method is verified.
