PROBLEM TO BE SOLVED: To accurately determine a movement direction of an object relative to an imaging apparatus.SOLUTION: A movement direction determination device for determining a movement direction of an object relative to an imaging apparatus has: an extraction unit which extracts a plurality of first feature points of the object in a first capture image captured by the imaging apparatus and extracts a plurality of second feature points corresponding to the plurality of first feature points from a second capture image captured by the imaging apparatus later than the first capture image; a calculation unit which calculates respectively position displacements between positions of the plurality of first feature points and positions of the plurality of second feature points corresponding to the plurality of first feature points; and a determination unit which determines a movement direction of the object relative to the imaging apparatus on the basis of difference of respective position displacements.SELECTED DRAWING: Figure 13

    【課題】 撮像装置に対する対象物の移動方向を精度よく判定できるようにする。【解決手段】 撮像装置に対する対象物の移動方向を判定する移動方向判定装置であって、前記撮像装置が撮像した第1の撮像画像から、画像内の前記対象物の第1の複数の特徴点を抽出し、前記第1の撮像画像よりも後の時間に前記撮像装置が撮像した第2の撮像画像から、前記第1の複数の特徴点に対応する第2の複数の特徴点を抽出する抽出部と、前記第1の複数の特徴点の位置と前記第1の複数の特徴点に対応する前記第2の複数の特徴点の位置との間の、位置の変位量をそれぞれ算出する算出部と、それぞれの前記位置の変位量の違いに基づいて、前記撮像装置に対する前記対象物の移動方向を判定する判定部とを有する。【選択図】図13
