Abstract
A captured image and corresponding observed pose data are captured or received. The captured image is captured by an image capturing device onboard a vehicle. The observed pose data is determined by a location sensor onboard the vehicle. The observed pose data indicates the pose of the vehicle when the image was captured. A map projection is generated based on map data and the observed pose data. The captured image and the map projection are analyzed by a pose metric network. The pose metric network determines a pose metric based on the analysis of the captured image and the map projection. The pose metric describes how similar the captured image is to the map projection.
