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.
