11. A vehicle surroundings monitoring method, comprising:
-
emitting infrared rays from a vehicle;
receiving infrared rays reflected from objects existing in the vicinity of the vehicle and creating an infrared image;
extracting from the infrared image those objects that reflect a quantity of infrared rays equal to or exceeding a prescribed quantity;
extracting the images of pedestrian candidates based on the shapes of the images of the extracted objects;
determining if the pedestrian candidates are structures based on the gray levels of the images of the pedestrian candidates; and
determining that the pedestrian candidates that have not been determined to be structures are pedestrians. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
