Abstract
In this paper we present a system for three-dimensional reconstruction of architectural scenes from uncalibrated videos. These videosmight be recorded using hand-held cameras, downloaded from the internet or taken from archival sources. Because we do not requireprior knowledge of the camera’s internal parameters such as focal length, center of projection, and radial distortion we can deal withvideos from uncontrolled sources. We present fast algorithms for 2D feature tracking on the GPU, real-time robust estimation andbundle adjustment. We also demonstrate a new type of feature, the viewpoint invariant patch (VIP), in its application to loop detectionand closing. Show more
