To provide a sign identification system which can identify a specific road sign to be identified, more reliably.SOLUTION: A sign identification system executes: sign extraction processing (S11) which extracts stop sign candidates M1, M2, M3, on the basis of a shape of a stop sign, from an image I(n) captured by a camera 2; lane extraction processing (S12) which extracts lines L1, L2 for marking a lane from the image I(n); intersecting point extraction processing (S14) which extracts an intersecting point P1 of a perpendicular L3 passing through the candidate M1 and the line L1, an intersecting point P2 of a perpendicular L4 passing through the candidate M2 and the line L1, and an intersecting point P3 of a perpendicular L5 passing through the candidate M3 and the line L2; and selection processing (S16) which selects a candidate which is located on the side of the lane on which the vehicle travels and closest to the vehicle, on the basis of the intersecting points P1, P2 and P3.SELECTED DRAWING: Figure 4

    【課題】識別すべき特定の道路標識を、より確実に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が撮影した画像I(n)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、M3を抽出する標識抽出処理(S11)と、画像I(n)から、車線を区画する線L1、L2を抽出する車線抽出処理(S12)と、候補M1を通る垂線L3と線L1との交点P1、候補M2を通る垂線L4と線L1との交点P2、および、候補M3を通る垂線L5と線L2との交点P3を抽出する交点抽出処理(S14)と、交点P1、P2、P3の座標に基づいて、自車線側に存在し、かつ、車両に最も近い候補を選択する選択処理(S16)とを実行する。【選択図】図4
