<P>PROBLEM TO BE SOLVED: To provide a device and a method for road surface projection capable of calling attention of a pedestrian in an easily understandable manner. <P>SOLUTION: Visible light cameras 11-1 to 11-4, and infrared ray cameras 12-1 to 12-4 pick up images of road surfaces on the front side, the rear side and the right side of a vehicle. A CPU 35 discriminates a pedestrian based on infrared ray images of the infrared ray cameras 12-1 and 12-2, and determines whether or not any pedestrian is present in an area of discrimination. If any pedestrian is present in this area of discrimination, the CPU 35 turns on a switch 18, and a projector 13-1 picks up an image of a pedestrian crossing picture on a road surface. Further, when the vehicle approaches, the CPU 35 turns on a switch 19, and a projector 13-2 picks up an image of a stop-line on the road surface. <P>COPYRIGHT: (C)2008,JPO&INPIT |
