OBSTACLE DETECTION SYSTEM AND METHOD, AND OBSTACLE DETECTION APPARATUS

摘要

An obstacle detection system (10) includes an image capturing apparatus (20) for capturing an image of a periphery of a vehicle and outputting an image signal, an obstacle detection apparatus (30) for detecting presence/absence of an obstacle from the image signal, and a lighting apparatus (40) mounted on the vehicle. The obstacle detection apparatus (30) controls turning on/off of the lighting apparatus (40) by a light status control unit (31). When a lighting state of the lighting apparatus (40) has changed, a difference image generating unit (34) generates a difference image between the image signal output from the image capturing apparatus (20) and an image signal of a past frame stored in an image data storing unit (35). An obstacle determining unit (38) determines the presence/absence of an obstacle based on the difference image.
