- 車両の路面周囲を撮像する画像入力手段と、入力した画像を処理して車両の路面周囲の認識対象物を認識する認識手段を有し、前記認識手段は前記画像入力手段によって得られた画像上の前記認識対象物の少なくとも一つの特徴に基づいて前記認識対象物を判定する第一の判定手段と、前記第一の判定手段が用いる特徴より多い特徴に基づいて前記認識対象物を判定する第二の判定手段を備えてなる路面標示認識装置であって、
前記認識手段は更に判定条件決定手段を備えており、前記判定条件検定手段は前記車両の周辺に前記認識対象物の特徴と形状が類似した路面標示が存在しない場合は前記第一の判定手段によって前記認識対象物を判定させ、前記車両の周辺に前記認識対象物の特徴と形状が類似した路面標示が存在する場合は前記第二の判定手段によって前記認識対象物を判定させることを特徴とする路面標示認識装置。 - 請求項1において、前記認識手段は認識すべき前記認識対象物の特徴と類似する路面標示の有無と認識すべき特徴数を記憶した記憶手段を有し、前記判定条件決定手段は認識すべき前記認識対象物によって決まる特徴数によって前記第一の判定手段と前記第二の判定手段を選択することを特徴とする路面標示認識装置。
- 請求項2において、前記記憶手段には認識すべき前記認識対象物から所定の範囲内に存在する前記認識対象物と所定の類似関係にある路面標示が記憶されていることを特徴とする路面標示認識装置。
