| 为解决倾斜摄影测量项目中 5镜头相机采集像片数量多，数据量大，空中三角测量及三维建模时间长，计算机硬件要求高，参与三维建模像片很多是多余的问题，本文对倾斜摄影三维建模像片的筛选方法进行研究。基于 .NET Framework框架，采用 C#编程语言设计开发了倾斜摄影像片筛选工具，实现对测区范围之外、像幅不完整、曝光不正常及重叠度过大像片自动化剔除。在剔除无效像片后，减少了数据存储容量，缩短了三维建模时间，提升了实景三维项目工作效率。 |

| In order to solve the problems of large number of photos collected by the five-lens cameras inoblique photogrammetry projects, large amounts of data, long aerial triangulation and 3D modeling time, high com.puter hardware requirements, and many 3D modeling photos being redundant, this article discusses the screeningmethod of oblique photography three-dimensional modeling photos is studied. Based on the .NET Framework frame.work and using the C# programming language, an oblique photography photo screening tool was designed and devel.oped to automatically eliminate photos outside the measurement area, with incomplete image frames, abnormal expo. sure, and excessive overlap. After eliminating invalid photos, the data storage capacity is reduced, the 3D modelingtime is shortened, the work efficiency of the real-life 3D projects is improved. |
