ABSTRACT:
A method and system for guiding a-vehicle comprises a location module for collecting location data for the vehicle. A vision module collects vision data for the vehicle. A maximum allowable correction duration and a maximum allowable vision-derived displacement are established for correction of a position of a vehicle. A location quality estimator estimates location quality data for the corresponding collected location data during an evaluation time window. A vision module estimates vision quality data for the corresponding collected vision data during the evaluation time window. A selector selects the application of location data or vision data based on the quality data and at least one of the maximum allowable correction duration and the maximum allowable vision-derived displacement for the evaluation time window or for an application interval trailing the evaluation time window.
