PROBLEM TO BE SOLVED: To provide a reverse running detection system which improves effectiveness of reverse running detection with an inexpensive configuration and is suitable for an effective avoidance measure.SOLUTION: A reverse running detection system comprises: imaging means (21) which images the rear of a vehicle; means (12) which detects distance mark (5) based on the rear image (20) obtained by the imaging means; and means (12) which recognizes distance number of the distance mark. The reverse running detection means preferably includes distance information recording means (14) and distance number change determination means (15).SELECTED DRAWING: Figure 1

    【課題】 安価な構成により逆走検知の実効性を向上させるとともに、有効な回避措置を行ううえで有利な逆走検知システムを提供する。【解決手段】 車両の後方を撮影する撮像手段(21)と、前記撮像手段に得られた後方画像(20)から距離標(5)を検出する手段(12)と、前記距離標の距離数を認識する手段(12)とを備えた。前記逆走検出手段は、距離情報記録手段(14)、距離数変化判定手段(15)をさらに含むことが好ましい。【選択図】 図1
