实景三维建模倾斜影像自动挑片方法研究与实现

Research and Implementation of Automatic Photo Selection Method for Real Scene 3D Modeling Oblique Image

为解决倾斜影像难以根据建模范围准确挑片的问题,本文通过对倾斜摄影POS数据和倾斜相机五镜头影像覆盖区域的研究,根据POS数据将所有镜头影像覆盖范围标识在对应空间位置上,利用程序进行空间分析与判读,自动获取建模范围涉及的所有影像列表,剔除无效影像后的数据量明显降低,有助于提高实景三维项目生产效率。

In order to solve the problem that it is difficult to accurately select the oblique image according to the modeling range,this paper studies the oblique photography POS data and the five lens image coverage area of the oblique camera,marks all the lens image coverage in the corresponding spatial position according to the POS data,uses the program for spatial analysis and interpretation,and automatically obtains the list of all images involved in the modeling range,the amount of data after eliminating invalid images is significantly reduced,which helps to improve the production efficiency of real scene 3 D projects.
