Creating architectural models from images

Abstract

We present methods for creating 3D graphical models of scenes from a limited numbers of images, i.e. one or two, in situations where no scene co-ordinate measurements are available. The methods employ constraints available from geometric relationships that are common in architectural scenes -such as parallelism and orthogonality together with constraints available from the camera. In particular, by using the circular points of a plane simple, linear algoritluns are given for computing plane rectification, plane orientation and camera calibration from a single image. Examples of image based 3D modelling are given for both single images and image pairs. © The Eurographics Association and Blackwell Publishers 1999.
