OBSTACLE DETECTION APPARATUS, OBSTACLE DETECTION SYSTEM HAVING SAME, AND OBSTACLE DETECTION METHOD
First Claim
1. An obstacle detection apparatus that detects, upon backing up of a vehicle, an obstacle from an image of a rear area of the vehicle, the obstacle detection apparatus comprising:
- a difference image creating unit that creates a difference image between an image captured when brake lights of the vehicle are on and an image captured when the brake lights of the vehicle are off; and
an obstacle determining unit that determines whether there is an obstacle, based on a location in an image where a difference occurs in the difference image.

Abstract
There is provided an obstacle detection apparatus capable of detecting an obstacle present at the rear of a vehicle even in a low illumination environment, without the need for a sensor other than an imaging apparatus. An obstacle detection apparatus (20) detects, upon backing up of a vehicle, an obstacle from a video of a rear area of the vehicle. The obstacle detection apparatus (20) includes a difference image creating unit (23) that creates a difference image between an image captured when brake lights of the vehicle are on and an image captured when the brake lights of the vehicle are off; and an obstacle determining unit (26) that determines whether there is an obstacle, based on a location in an image where a difference occurs in the difference image obtained by the difference image creating unit (23).
