VEHICLE OBSTACLE DETECTION DEVICE AND VEHICLE OBSTACLE DETECTION METHOD

摘要

PPROBLEM TO BE SOLVED: To increase accuracy of detecting an obstacle which becomes an obstacle to vehicle traveling including a road shape at the side part of a vehicle. PSOLUTION: A vehicle obstacle detection device is provided with: a light beam irradiating means 11 for irradiating an obstacle present beside the vehicle with a light beam for obstacle detection with prescribed length from the side edge of a vehicle; a photographing means 12 for photographing a prescribed range including the light beam for obstacle detection emitted from the light beam irradiating means 11; and an image processing means 13 for detecting the state change in the light beam for obstacle detection to be acquired by tracing the light beam for obstacle detection photographed by the photographing means 12. Then, an obstacle present beside the vehicle is detected based on the detection result. PCOPYRIGHT: (C)2009,JPO&INPIT
