A position determining system for a vehicle comprises an imaging unit for
collecting image data. A wireless device reads or interrogates a radio
frequency identification tag. An identification module determines whether
the collected image data contains a visual landmark. A confirmation
module determines whether the identified visual landmark is associated
with a corresponding radio frequency identification tag having a
particular tag identifier. A range finder or distance estimator
determines a position offset of the vehicle with respect to the
identified visual landmark. A data processor determines a vehicular
position of the vehicle based on the determined position offset and a
stored reference position associated with at least one of the visual
landmark and the radio frequency identification tag.
