To enable an approaching object to be continuously detected even in the case that a door is opened and closed.SOLUTION: An approaching object detection device 20 for detecting an approaching object that approaches includes: a movement vector detection unit 21 for detecting a movement vector of an object by comparing a first photographic image photographed by a camera 11 with a second photographic image photographed by the camera at a time later than the time when the first photographic image is photographed; a shake detection unit 22 for detecting a shake vector of the camera 11 on the basis of the movement vector of the object; a time specification unit 23 for acquiring opening/closing information showing whether a door is closed, and specifying a time when the door is closed on the basis of the acquired opening/closing information; and an approaching object detection unit 24 for correcting the movement vector of the object on the basis of the shake vector of the camera 11 at the time when the door is closed, and detecting the position of the approaching object on the basis of the corrected movement vector of the object.SELECTED DRAWING: Figure 1

    【課題】ドアが開閉された場合においても、接近物検出を継続できるようにする【解決手段】接近する接近物を検出する接近物検出装置20であって、カメラ11によって撮影された第1撮影画像と、前記第1撮影画像が撮影された時刻よりも後の時刻に前記カメラによって撮影された第2撮影画像とを比較することによって、物体の移動ベクトルを検出する移動ベクトル検出部21と、物体の移動ベクトルに基づいて、カメラ11の揺れベクトルを検出する揺れ検出部22と、ドアが閉まっているか否かを示す開閉情報を取得し、取得した開閉情報に基づいてドアが閉まった時刻を特定する時刻特定部23と、ドアが閉まった時刻におけるカメラ11の揺れベクトルに基づいて物体の移動ベクトルを補正し、補正された物体の移動ベクトルに基づいて、接近物の位置を検出する接近物検出部24と、を備える。【選択図】図1
