METHOD AND APPARATUS FOR UPDATING ROAD MAP GEOMETRY BASED ON PROBE DATA

摘要

A method is provided for generating and revising map geometry based on probe data. A method may include: map-matching a probe data point location to a roadway; identifying an established vertex corresponding to the location along the roadway; determining an average position corresponding to the established vertex; determining a variance of the established vertex; determining a number of data points having contributed to the average position and the variance of the established vertex; calculating a revised average position and a revised variance using the probe data point location, the average position, the variance, and the number of data points; and causing storage of the revised average position and revised variance for the established vertex in the memory and increasing the number of data points having contributed to the average position and the variance of the established vertex to facilitate update of a map representation including the established vertex with the revised average position.
