Abstract
Pose estimation is performed using a scene structure captured in a query image and reference images from a database. Each of the reference images has an associated position estimate. Direction vectors are generated that describe directions between an unknown position of a camera center for the query image and a reference camera center for each reference image based on the query image and the plurality of reference images. The direction vectors may be generated using, e.g., homographies, essential matrices, or fundamental matrices. A pose estimation with six degrees of freedom is determined using the direction vectors and the associated position estimate for each reference image. The pose estimation, for example, may be determined by solving a three-point pose problem using the direction vectors and the associated position estimate for each reference image.
