An object detection device () is provided with: a video image converting section () converting an input video image in which surroundings of a vehicle are shot, to a characteristics video image into which image characteristics have been extracted from the input video image; a video images-classified-by-distance extracting/composing section () extracting areas which differ according to distances from the characteristics video image on the basis of the distance from a vehicle and composing the areas; a first object detecting section () scanning a composite video image to perform first object detection processing; an object-candidate position specifying section () determining an object-candidate position from a result of the first object detection processing; a second object detecting section () performing second object detection processing for the object-candidate position; and an object position identifying section () identifying an object position from a result of the second object detecting section.

Object detection device, object detection method, and object detection program

A system for controlling vehicle opening/closing element has a radiation block for irradiating near-infrared light to a peripheral region of an opening/closing element; a photographing block that photographs an image irradiated with the near-infrared light; a hand region extraction block that extracts a user's hand region from brightness of an image photographed by the photographing block; a motion detection block that detects motions of the user's hand from the extracted hand region; and a control block that determines whether or not the detected motions coincide with previously-set predetermined motions and that commands operation of the opening/closing element in accordance with the determined motions.
