Computer vision technique for 3D model reconstruction of historical building from photographs

Résumé

The architectural heritage is considered part of every nation. The historical buildings represent people’s identity and past. Nowadays the technology allows to produce 3D models of buildings using laser scanners or photogrammetry, but these technologies cannot be used to reconstruct from one or few past images, as in the case of lost buildings. Moreover, pictures taken might not provide a clear image of details of historical buildings. This paper presents a computer vision technique for 3d model reconstruction of historical buildings. A software proof-of-concept application is presented to reconstruct historical buildings. The new approach however requires high computational resources and might provide the solution in
cases where a historical building is described by one single picture.
