Reconstruction of Architectural Scenes for Muncalibrated Photos and Maps

摘要

We consider the problem of reconstructing ar- chitectural scenes from multiple photographs taken from arbi- trary viewpoints. The original contribution is the use of a map as a source of geometric constraints to obtain in a fast and simple way a detailed model of a scene. We suppose that images are un- calibrated and have at least one planar structure as a facade 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 im- Ages and map.
