基于无人机航测的DEM数据生产及编辑

Processing and editing of DEM data from the UAV aerial

DEM数据结合高分辨率航测影像,利用虚拟三维技术,可真实地反映工区地形地貌,为野外勘探精细化生产提供可视化信息服务。本文详细介绍了目前发展较迅速的无人机航测技术DEM数据的生产流程,并利用具体的案例进行了实际的操作展示,最后通过精度的比较和验证,说明无人机生产的DEM数据具有较高精度及可靠性,可完全满足物探生产的需要。

Combined with high--resolution aerial photograph andvirtual 3D technology, DEM data can reflect thelandform and geomorphology of the project area, and provide visual information service for exploration seismology. This pa per describes the current development of UAV and the production process of DEM, and uses a specific case demon- strating the operation. The accuracy indicates that the DEM of UAV has high precision and reliability and can fully meet the needs of prospecting.
