Detection and 3D Reconstruction of Buildings from Aerial Images

Abstract

In this paper, we consider the problem of detection and 3D reconstruction of buildings from aerial images of the scene and usage of orientation data (camera parameters, GPS, etc.). Presently-available methods for solving this problem are inefficient on large amounts of data, where most of the data do not need thorough processing. In this work, we employ methods that find and analyze line segments on the image. This approach allows us to use image preprocessing based on line segment analysis, thereby reducing the amount of data that require computationally complex operations.
