Buildings Recognition and Camera Localization Using Image Texture Description
3D GIS model/2D image registration called much attention in the recent years because of its vast range of potential applications in real and virtual navigation. However, automatic registration remains until now a challenge. This paper presents a methodology for enhancing and complementing a GIS database of buildings with a descriptor of their texture by using information extracted from a reference images. This descriptor is used to locate any other image by searching similar texture in the image. Then the absolute position and orientation of the camera of the new image can be computed if the camera parameters (like focal length) are known. The paper proposes a technique that can be used for achieving the identification of the facade in the photograph, calibrated camera geolocation and discusses the quality of the results.
