Abstract
A method for generating accurate lane level maps based on coarse map information and image sensor data captured during the pass of a sensor carrying vehicle along a road. The method generates accurate lane estimates including any of the center of each lane, the number of lanes, and the presence of any bicycle paths, and entrance and exit ramps, merging of two lanes into one lane, or the expansion of one lane into two lanes, using a computer-implemented method where the coarse map data and the image sensor data are subjected to dual reversible jump-Markov chain Monte Carlo filtering.
