Obstacle detection device for vehicle and method thereof

An obstacle detection device (10) for a vehicle that detects obstacles using a distance to an object calculated by image processing and a distance to the object calculated by radar ranging. This obstacle detection device (10) includes a measuring means (12,16) for measuring an amount of movement of the object at a predetermined interval of time by image processing and a measuring means (14) for measuring an amount of movement of the object at a predetermined interval of time by radar ranging, and does not determine the object to be an obstacle when the two amounts of movement are not consistent.
