无人机倾斜摄影测量技术在城中村改造测绘中的应用及精度分析OA

With the acceleration of urbanization,the transformation of villages in cities has become an important part of urban planning and management.Traditional surveying and mapping methods have problems such as low efficiency,high cost,and insufficient accuracy in complex terrain and high-density building environments.As an emerging surveying and mapping technology,UAV oblique photogrammetry can efficiently obtain high-precision geographical information data through multi-angle shooting and three-dimensional modeling.This paper discusses the application of UAV oblique photogrammetry in urban village reconstruction surveying and mapping,and analyzes its advantages in terrain surveying and mapping,building structure analysis,demolition planning,etc.Through actual case studies,the remarkable effect of this technology in improving surveying and mapping efficiency,operating costs and providing accurate data support is verified.The research results show that UAV oblique photogrammetry provides scientific basis and technical support for the renovation of villages in cities,and has broad application prospects.
