1. A parking recognition method for recognizing a vehicle parked on at least one parking surface, comprising:
acquiring a plurality of images photographed by cameras, in relation to the at least one parking surface and the vehicle;
determining a parking recognition time point as well as a corresponding camera for parking recognition (“a parking recognition camera”) among the cameras, based on a difference in images (“image difference”) between the plurality of images, which are time-sequentially continued (“the plurality of time-sequentially continuous images”);
setting a parking surface occupying-judgment area for the at least one parking surface, based on an image photographed by the parking recognition camera at the parking recognition time point;
setting a vehicle recognition area for the vehicle, based on the image photographed by the parking recognition camera at the parking recognition time point; and
determining whether the vehicle is parked on the at least one parking surface, based on the parking surface occupying-judgment area and the vehicle recognition area.
