Image-based pose estimation using a compact 3D model

Image-based localization finds the pose an image was taken in. Our method uses the MPEG Compact Descriptors for Visual Search framework [1] to build a compact 3D model from the 3D reconstruction of a city. Then using an image retrieval the closest match for a query image is found and the pose is estimated. Our method is able to determine an estimate of the pose within a few meters of the actual one.
