Abstract
Preferably, an object such as a vehicle is detected regardless of a distance up to the object. A device for recognizing external worlds that analyzes an image acquired by capturing the vicinity of a self-vehicle includes: a processing area setting unit setting a first area of the image indicating a short range and a second area of the image indicating a long range, a first object detecting unit detecting the object by means of a first classifier in the set first area, a second object detecting unit detecting the object by considering even a background pattern by means of a second classifier in the set second area, a rectangular correction unit correcting a detected object rectangular shape and a time to collision (TTC) computing unit computing a prediction time up to a collision based on the detected object rectangular shape.
