Determining position of a vehicle with reference to a landmark
First Claim
1. A position determining system for a vehicle, the system comprising:
- an imaging unit for collecting image data from a vehicle;
a wireless device for reading a radio frequency identification tag;
an image processor for determining whether the collected image data contains a visual landmark;
a confirmation module for determining whether the identified visual landmark is associated with a corresponding radio frequency identification tag having a particular tag identifier;
a range finder for determining a position offset of the vehicle with respect to the identified visual landmark;
a data processor for determining 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.

Abstract
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.
