摘要: 利用倾斜摄影技术生成的实景三维模型一般都仅仅作为一种浏览演示的方式,使用方式较为粗糙单一,其成果并没有真正应用到常规测绘产品生产的各个环节。本文对一种利用倾斜摄影三维模型的房檐改正方法进行了分析与精度评估。在已有倾斜摄影快速建立三维模型的基础上,采用建筑物立面散点正交原理直接对倾斜摄影三维模型居民地区域进行去房檐采集。该方法提供了一种全内业测图的模式,对地形图生产方法的改进具有重要意义。

Abstract: 3D model, generated by oblique photography technology generally, is usually used as a way to browse the demo nstration. Its usage is simple and crude. Thus, the results are not really applied to each link of conventional surveying and mapping production. This paper studies the accuracy evaluation for method of eave correction based on oblique photography 3D model.On the basis of the exised oblique photography 3D model,we use the facade messy point orthogonal principle to correct the eaves of oblique photography 3D model of residential area. This method provides a kind of intra industry mapping model, which is of great significance to the improvement of topographic map production.

Key words: oblique photography 3D model, the facade messy point orthogonal principle, eave correction, accuracy evaluation
