Summary:A method and system for guiding a vehicle comprises a location module (26) (e.g., location-determining receiver) for collecting preliminary location data for the vehicle. A vision module (22) collects vision-derived location data for the vehicle during an evaluation time window. A location quality estimator (24) estimates location quality data for the corresponding collected preliminary location data during an evaluation time window. A vision module (22) estimates vision quality data for the corresponding collected vision-derived location data during the evaluation time window. A adjuster (110) adjusts the preliminary location data to a revised location data based on the vision-derived location data such that the revised location data is registered with or generally coextensive with the vision-derived location data, if the vision quality data exceeds the minimum threshold level.
