Abstract
A method performed by one or more processors includes: obtaining an original intensity map including original elements having respective signal intensities with respect to a road surface, the signal intensities based on sensing of a vision sensor arranged on a moving object that is moving on a road including the road surface, wherein each of the original elements has a respective local neighborhood of neighboring original elements; generating a local intensity map by determining local values respectively corresponding to the original elements of the original intensity map, wherein the local values are determined based on the original elements in the respectively corresponding local neighborhoods; generating a normalized intensity map by normalizing the original intensity map based on the local intensity map; and recognizing the road surface based on the normalized intensity map.
