ABSTRACT:
An apparatus for recognizing an environment includes imaging unit (10) for picking up surroundings of a vehicle equipped with the apparatus so as to obtain a surrounding image, filter processing unit (20) for providing filter processing to the surrounding image for each predetermined sampling interval so as to obtain a process image and edge information, processed information memorizing unit (30) for memorizing the process image, image finite differentiating unit (40) for obtaining a difference image between the process image and a process image before an arbitrary sampling interval, frequency accumulating unit (50) for accumulating the number of moving pixels for each moving direction based on the edge information and the difference image so as to obtain a cumulative value, and determining unit (60) for performing determination of a surrounding environment in accordance with the cumulative value of the frequency accumulating unit (50).
