To provide a movement vector detection device configured for detecting a movement vector of a vehicle by extracting a vehicle area from a captured image to suppress movement vector detection errors.SOLUTION: A movement vector detection device 10 has an image input unit 11, a vehicle area extraction unit 12, an edge image creation unit 13, a straight line detection unit 14, and a determination processing unit 15. The movement vector detection device 10 inputs a captured image of a road including an intersection, extracts the vehicle area containing the vehicle from the captured image, sets a reference point in the vehicle area, and detects the movement vector of the vehicle by tracing the reference point. The movement vector detection device 10 sets a specific point on a lower side of the vehicle area as the reference point when the vehicle drives straight and sets the specific point on the straight line portion positioned at the bottom of the image among the straight line included in the edge image of the vehicle area as a reference point when the vehicle turns.SELECTED DRAWING: Figure 1

    【課題】撮像画像から車両領域を抽出して車両の移動ベクトルを検出するように構成された移動ベクトル検出装置において、移動ベクトルの検出誤差を抑制する。【解決手段】移動ベクトル検出装置10は、画像入力部11、車両領域抽出部12、エッジ画像作成部13、直線検出部14及び判定処理部15を有する。移動ベクトル検出装置10は、交差点を含む道路の撮像画像を入力し、前記撮像画像から車両を内包する車両領域を抽出し、前記車両領域に基準点を設定し、及び前記基準点を追跡して前記車両の移動ベクトルを検出する。移動ベクトル検出装置10は、前記車両が直進する場合には前記車両領域の下辺上の特定点を前記基準点に設定し、前記車両が折進する場合には前記車両領域のエッジ画像に含まれる直線部分のうちの画像下部に位置する直線部分上の特定点を基準点に設定する。【選択図】図1
