Reconstruction of Architectural Scenes from Uncalibrated Photos and Maps

چکیده
In this paper we consider the problem of reconstructing architectural scenes from multiple photographs taken from arbitrarily viewpoints. The original contribution of this work is the use of a map as a source of geometric constraints in order to obtain in a fast and simple way a detailed model of a scene. We suppose images are uncalibrated and have a t least one planar structure as a faqade for exploiting the planar homography induced between world plane and image to calculate a first estimation of the projection matrix. Estimations are improved by using correspondences between images and map. We show how these simple constraints can be used to calibrate the cameras and recover the projection matrices for each viewpoint. Finally, triangulation is used to recover 3D models of the scene and to visualise new viewpoints. Our approach needs minimal a priori information about the camera being used. A working system has been designed and implemented to allow the user to interactively build a model from uncalibrated images from arbitrary viewpoints and a simple map.

متن کاملArchitectural Scene Reconstruction from single or Multiple Uncalibrated Images
In this paper we present a system for the reconstruction of 3D models of architectural scenes from single or multiple uncalibrated images. The partial 3D model of a building is recovered from a single image using geometric constraints such as parallelism and orthogonality, which are likely to be found in most architectural scenes. The approximate corner positions of a building are selected inte...

متن کامل3d Reconstruction of Architectural Scenes from Uncalibrated Video Sequences
In this paper we present a system for three-dimensional reconstruction of architectural scenes from uncalibrated videos. These videos might be recorded using hand-held cameras, downloaded from the internet or taken from archival sources. Because we do not require prior knowledge of the camera’s internal parameters such as focal length, center of projection, and radial distortion we can deal wit...
متن کاملAutomated Architecture Reconstruction from Close-range Photogrammetry∗
We describe a method of automated reconstruction of buildings from a set of uncalibrated photographs. The method proceeds in two steps (i) Recovering the camera corresponding to each photograph and a set of sparse scene features using uncalibrated structure from motion techniques developed in the Computer Vision community. (ii) A novel plane-sweep algorithm which progressively constructs a piec...
