To provide a sign identification system which can identify a sign of a lane on which the vehicle travels, even if there are a plurality of signs in an image.SOLUTION: A sign identification system executes: extraction processing (S12) which extracts stop sign candidates M1, M2 on the basis of a shape of a stop sign, from each of first and second images I1 and I2 captured by a camera 2; calculation processing (S14) which calculates the amount of increase in size of the candidate M1 in the second image I2 with respect to the size of the candidate M1 in the first image I1, and the amount of increase in size of the candidate M2 in the second image I2 with respect to the size of the candidate M2 in the first image I1; and selection processing (S15) for selecting a candidate M1 having the largest amount of increase, as a candidate which is located on the side of the lane on which the vehicle travels and closest to the vehicle.SELECTED DRAWING: Figure 4

    【課題】画像中に複数の標識が存在する場合でも、自車線の標識を識別できる標識識別システムを提供する。【解決手段】カメラ2が撮影した第1の画像I1および第2の画像I2のそれぞれから、一時停止標識の形状に基づいて、一時停止標識の候補M1、M2を抽出する抽出処理(S12)と、第1の画像I1中の候補M1のサイズに対する第2の画像I2中の候補M1のサイズの増加量と、第1の画像I1中の候補M2のサイズに対する第2の画像I2中の候補M2のサイズの増加量とを計算する計算処理(S14)と、増加量が最も大きい候補M1を、自車線側に存在し、かつ、前記車両に最も近い候補として選択する選択処理(S15)とを実行する。【選択図】図4
