PhotoBuilder - 3D Models of Architectural Scenes from Uncalibrated Images

We address the problem of recovering 3D models from uncalibrated images of architectural scenes. We propose a simple, geometrically intuitive method which exploits the strong rigidity constraints of parallelismand orthogonality present in indoor and outdoor architectural scenes. We show how these simple constraints can be used to calibrate the cameras and to recover the projection matrices for each viewpoint. The projection matrices are used to recover partial 3D models of the scene and these can be used to visualise new viewpoints. Our approach does not need any a priori information about the cameras being used. A working system called PhotoBuilder had been dehas encouraged others to design interactive systems. In this paper we propose a much simpler approach to construct a 3D model and generate new viewpoint images by exploiting strong constraints present in the scenes to be modelled. In the context of architectural environments, the constraints which can be used are parallelism and...
