A method for determining the position and orientation of a camera which does not rely on the use of special markers. A set of reference images are stored, together with camera pose and feature information for each image. A first estimate of camera position is determined by comparing the current camera image with the set of reference images. A refined estimate can be obtained using features matched in the current image and in a subset of similar reference images, and in particular, the 3D positions of those features. A consistent 3D model of all stored feature information need not be provided. |
