METHOD AND APPARATUS FOR UPDATING ROAD MAP GEOMETRY BASED ON RECEIVED PROBE DATA
First Claim
1. A method comprising:
- receiving probe data from a first period of time, wherein the probe data from a first period of time is from a plurality of probes within a predefined geographic region;
generating a first image of the predefined geographic region based on the probe data from the first period of time;
receiving probe data from a second period of time different from the first period of time, wherein the probe data from the second period of time is from a plurality of probes within the predefined geographic region;
generating a second image of the predefined geographic region based on the probe data from the second period of time;
comparing the first image to the second image; and
generating a revised route geometry based on changes detected between the first image and the second image.

Abstract
A method is provided for generating and revising map geometry based on a received image and probe data. A method may include: receiving probe data from a first period of time, where the probe data from a first period of time is from a plurality of probes within a predefined geographic region; generating a first image of the predefined geographic region based on the probe data from the first period of time; receiving probe data from a second period of time different from the first period of time, where the probe data from the second period of time is from a plurality of probes within the predefined geographic region; generating a second image based on the probe data from the second period of time; comparing the first image to the second image; and generating a revised route geometry based on changes detected between the first image and the second image.
