Vehicular navigation based on site specific sensor quality data
First Claim
1. A method for determining a location of a vehicle, the method comprising:
- establishing an estimate of reception quality data versus cellular locations for work area and an estimate of optical quality data versus cellular location data;
determining reception location data and optical location data within a first cell of the cellular locations of a work area for a vehicle;
referencing the established estimate to retrieve relevant reception quality data and relevant optical quality data associated with the first cell; and
selecting at least one of the reception location data and the optical location data as refined location data associated with the first cell based on the relevant reception quality data and relevant optical quality data.

Abstract
A method and system for determining a location of a vehicle, the method comprises determining reception location data within a first cell of a work area for a vehicle. A reception quality estimator estimates reception quality data for the corresponding reception location data for the first cell. Optical location data is determined within a first cell of a work area for a vehicle. An optical quality estimator estimates optical quality data for the corresponding optical location data for the first cell. A data processor selects at least one of the reception location data and the optical location data as refined location data associated with the first cell based on the estimated reception quality data and estimated optical quality data.
