PROBLEM TO BE SOLVED: To provide a technology that detects a change of opening degree of door on the basis of a photographic image obtained by a camera that photographs the periphery of the vehicle.SOLUTION: An opening-degree change detection device for a door comprises an analyzing section and a detecting section. On the basis of a plurality of photographic images obtained by a camera attached to a door of the vehicle and provided for photographing the periphery of the vehicle, the analyzing section analyzes an amount of movement vector of a characteristic point included in the photographic image and coordinates around a rotation. On the basis of the result of the analysis by the analyzing section, the detecting section detects a change of opening degree of the door.SELECTED DRAWING: Figure 9

    【課題】車両の周辺を撮影するカメラで得られた撮影画像に基づいてドアの開度変化を検出する技術を提供する。【解決手段】ドアの開度変化検出装置は、解析部及び検出部を備える。前記解析部は、車両のドアに取り付けられ前記車両の周辺を撮影するカメラで得られた複数の撮影画像に基づいて、前記撮影画像に含まれる特徴点の移動ベクトル量及び旋回中心座標を解析する。前記検出部は、前記解析部の解析結果に基づいて、前記ドアの開度変化を検出する。【選択図】図9
