摘　　要：本文概述了倾斜摄影实景三维建模相关技术,分析了实景三维数据常用格式OpenSceneGraph Binary Scene Data(OSGB)文件的数据存储结构,研究了目前实景三维模型常用的修饰修补方法。从实际应用需求出发,设计了实景模型编辑工具的技术开发路线,实现了对实景三维模型的切割和修平两种编辑功能,为倾斜摄影实景三维模型的数据生产提供了工具支持。In this paper, it expounds the basic principle and process of oblique photography and real three Dimensions(3D) modeling, analyses the data structure of the OpenSceneGraph Binary Scene Data(OSGB)file, studies how to fix and modify the real 3D model, and designes a model editor implements the model cutting and flatting function based on the actual demand of practical application, which provides tool support for real 3D model production.
