摘　　要：倾斜摄影实景三维模型是由连续的三角网通过纹理贴图组成,模型上各地理要素具有“一张皮”的特点。针对无法管理与编辑模型上各地理对象的问题,该文提出基于倾斜摄影实景模型进行单体化建模的技术方法,通过对三维模型进行单体化操作,得到能够精确表达三维产权关系、且与地形匹配良好的三维地籍模型,为模型中地理对象属性的查询、管理和应用提供方便;对明晰表达三维空间中的权属状况,减少法律纠纷,对其他省市的相关三维地籍项目有借鉴价值和指导意义。The 3D model of oblique photography is composed of a continuous triangular network through texture mapping,and the various physical elements on the model have the characteristics of"one skin."Aiming at the problem that it is impossible to manage and edit geographical objects on the model,this paper proposes a technical method for singulation modeling based on oblique photographic real-life models.By singulation operations on the 3D model,a 3D cadastral model that can accurately express the 3D property rights relationship and matches the terrain well is obtained,providing convenience for the query,management and application of geographical object attributes in the model.Therefore,it has reference value and guiding significance for clearly expressing the ownership status in three-dimensional space,reducing legal disputes,and related three-dimensional cadastral projects in other provinces and cities.
