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.

Abstract: A method of determining a signal state of a target traffic light includes: acquiring an isolated image of the target traffic light from an input image of the target traffic light, wherein the input image is captured when the vehicle is at a position, wherein the isolated image is acquired using image processing on the input image, the input image having been captured by a camera module of the vehicle; acquiring information about the target traffic light based on a map position in map data, the map position corresponding to the position of the vehicle when the input image is acquired; and determining the signal state of the target traffic light based on the isolated image of the target traffic light and based on the information about the target traffic light.
