城区与山区无人机影像重建对比及精度分析

利用无人机通过视觉三维重建处理是进行地形表面重建的重要手段,具有响应快速、精度较高、适应性强的优点。由于城区与山区地面三维特性不同,利用无人机影像重建在精度和覆盖度上也有所不同。为探究无人机影像三维重建在地面典型城区与山区区域的不同,该文在利用无人机影像进行三维重建的基础上,对城区与山区重建结果的精度和覆盖率进行统计,分析不同区域下的重建质量,为后续无人机在不同区域的重建任务提供参考。

The use of UAV through visual 3D reconstruction is an important means of terrain surface reconstruction,which has the advantages of fast response,high accuracy and strong adaptability.Due to the difference of three-dimensional characteristics between urban areas and mountainous areas,UAV image reconstruction is also different in accuracy and coverage.In order to explore the difference of UAV image 3D reconstruction in typical urban areas and mountain areas,on the basis of using UAV images for 3D reconstruction,this paper makes statistics on the accuracy and coverage of urban and mountain reconstruction results.The reconstruction quality in different areas is analyzed in order to provide reference for subsequent UAV reconstruction tasks in different areas.
