The ambiguity on the reconstruction is restricted from projective to metric through self-calibration. A fl exible multi-view stereo matching scheme is used to obtain a dense estimation of the surface geometry. From the computed data different types of visual models are constructed. Besides the traditional geometry- and image-based approaches, a combined approach with view-dependent geometry and texture is presented. As an application fusion of real and virtual scenes is also shown.

A few years ago the main applications of 3d modeling in vision were robot navigation and vi- sual inspection. Nowadays however the emphasis has changed. There is more and more demand for 3D mod- els in computer graphics, virtual reality and commu- nication. This results in a change in the requirements. The visual quality of the models becomes the main point of attention. There is an important demand for simple and fl exible acquisition procedures. Therefore calibrationshouldbeabsentorrestrictedtoaminimum. 208Pollefeys et al. Manynewapplicationsalsorequirerobustlowcostac- quisition systems. This stimulates the use of consumer photo- or video cameras. In this paper we present an approach that can be used to obtain several types of visual models from im- agesacquiredwithanuncalibratedcamera.Theuserac- quires the images by freely moving the camera around an object or scene.
