实景三维模型在划定河道管理范围中的应用研究

Research on the Application of Real 3D Model in Demarcating River Management Scope

采用无人机搭载多镜头航摄仪进行倾斜航摄,利用生产的实景三维模型,进行讨赖河嘉峪关段河道管理范围线的划定,验证利用实景三维模型划定河道管理范围的可行性。结果表明:实景三维模型能满足河道管理范围线划定要求,可提高展示效果,减少外业工作量,为河道管护提供全生命周期服务。

UAV equipped with multi-lens aerial camera was used for oblique aerial photography,and the actual 3D model was used to delineate the river management scope line of the Jiayuguan section of Tulai River,verifying the feasibility of using the real 3D model to delineate the river management scope.The results show that the 3D model can meet the requirements of demarcating the scope line of river management,improve the display effect,reduce the field work,and provide the whole life cycle service for river management and protection.
