摘　　要：由于垦造水田项目多,分布散,山塘周围地形普遍较复杂、陡峭,依靠人工测量存在一定危险性,且效率较低。为快速准确完成垦造水田项目山塘库容核算,本文采用无人机倾斜摄影测量技术,通过高分辨率倾斜拍摄、布设少量像控点、对山塘进行三维建模,基于三维模型密集提取高程点,生成三角网和方格网,换算为土方进行库容核算,从目前实践来看,对于同类项目,具有一定参考意义。Due to the large number and scattered distribution of paddy field projects,the surrounding terrain of mountain ponds is generally complex and steep,relying on manual surveys is dangerous and low in efficiency.In order to quickly and accurately complete the calculation of the storage capacity of mountain ponds for the reclamation of paddy fields,this paper adopts drone tilt photography technology,through high-resolution tilt shooting,a small number of image control points,3D modeling of mountain ponds,and intensive extraction of elevations based on the 3D model Points,generate triangulation and square grids,and convert them to earthwork for storage capacity calculation.Judg-ing from current practice,it has certain reference significance for similar projects.
