To provide a road surface marking recognition device capable of recognizing presences of road surface markings that cannot normally be detected.SOLUTION: A road surface marking recognition device includes an acquisition processing section 40, a marking detection section 52, an information acquisition section 52, a marking determination section 52, an information determination section 52, and a re-detection section 52. The marking determination section determines whether or not there is a road surface marking candidate detected by the marking detection section in an own lane in which an own vehicle is traveling. When it is determined that the detected road surface marking candidate does not exist, the information determination section determines whether or not the acquired peripheral information includes information about the road surface marking of the own lane. When it is determined that the information about the road surface marking is included, the re-detection section adjusts a parameter relating to the detection so that the road surface candidates can be easily detected than detecting by the marking detection section in an estimated area where the road surface marking exists in the own lane and that is estimated based on the information relating to the road surface marking and detects again the road surface marking candidates.SELECTED DRAWING: Figure 2

    【課題】通常検知できない路面標示の存在を認識可能な路面標示認識装置を提供する。【解決手段】路面標示認識装置は、取得処理部40と、標示検知部52と、情報取得部52と、標示判定部52と、情報判定部52と、再検知部52と、を備える。標示判定部は、自車両が走行する自車線に、標示検知部により検知された路面標示候補が存在するか否か判定する。情報判定部は、検知された路面標示候補が存在しないと判定された場合に、取得された周辺情報に、自車線の路面標示に関する情報が含まれているか否か判定する。再検知部は、路面標示に関する情報が含まれていると判定された場合に、路面標示に関する情報に基づいて推定された、自車線において路面標示が存在する推定領域において、標示検知部による検知よりも路面標示候補を検知しやすくするように、検知に関するパラメータを調整し、路面標示候補を再検知する。【選択図】図2
