摘要
传统的城市地形测绘往往依赖于航空摄影、激光雷达等技术手段,虽然可以获取大范围的地形数据,但在地形细节和建筑物表面质地等方面存在一定的局限性。而倾斜摄影测量技术的出现,为解决这一问题提供了新的思路,通过倾斜摄影系统,可以在航拍过程中获取多个视角的高分辨率影像,结合后续的数据处理和建模技术,实现对城市地形和建筑物的精细化测绘和三维重建。目前已得到广泛应用,取得了很好的经济效益和社会效益。
Traditional urban terrain surveying often relies on techniques such as aerial photography and LiDAR.Although it can obtain large-scale terrain data,there are certain limitations in terms of terrain details and building surface texture.The emergence of oblique photogrammetry technology provides new ideas for solving this problem.Through oblique photogrammetry systems,high-resolution images from multiple perspectives can be obtained during aerial photography.Combined with subsequent data processing and modeling techniques,precise surveying and 3D reconstruction of urban terrain and buildings can be achieved.At present,it has been widely applied and has achieved good economic and social benefits.
