| Abstract: | Based on the ecological restoration project of the ecological zone around Chengdu city, the fusion monitoring technology of inclination photography and LiDAR technology is realized by using the Feima D200 UAV. Through 3D model making, large-scale topographic map production, point cloud processing, grid computing, precision evaluation and other steps, it is verified that the method of inclination photography and airborne LiDAR can meet the accuracy of 1∶500 topographic map and grid measurement, and it provides a guidance for the later UAV surveying and mapping. |
