倾斜摄影测量技术在1:500地形图更新中的应用

Application of Tilt Photogrammetry in the Update of 1:500 Topographic Map

在测绘过程中,会应用到无人机倾斜摄影测量技术,该测绘技术主要依靠多镜头倾斜相机搭载相应的无人机平台来获取相应的数据,进而建立相应的三维模型。文章针对倾斜摄影测量技术在1:500地形图更新中的应用进行分析,并结合30 km^(2)的实际案例进行验证,经过实验发现,该项目的精度和质量均符合相关要求,从而进一步证实了该技术在地图更新中的可行性。

In the process of mapping,UAV tilt photogrammetry is applied.The technology gets relevant data by multi-lens tilt camera on UAV platform to establish corresponding 3-dimensional model.This paper analyzes the application of inclined photogrammetry technology in the 1:500 topographic map update.The tech’s practice in a case of 30km2 is tested to meet concerned requirement,which further confirms the technology’s feasibility in map update.
