3D Building Reconstruction for 3D City Model Using UAV images

Abstract

3-D reconstruction of buildings in urban areas is one of the highlighted issues in photogrammetry, remote sensing, computer vision, and computer graphic. It can be used in various fields such as urban planning, construction, disaster management, navigation system, and cyber city .This paper presents an approach for 3D reconstruction model of buildings from urban area for 3D visualization. The model is generated automatically from a single image taken by UAV (Unmanned aerial vehicles). Most methods used two or more images for 3D building reconstruction. The previous methods take much time to detect and match feature points in each image and consume more memory space for multiple images. The proposed system can extract 3D geometry information from a single image without knowing the priori parameters. The building features are extracted using modified building feature extraction algorithm and then reconstruct it 3D model using proposed 3D box method. The proposed method can reduce processing time and memory space by using a single image for 3D reconstruction.
