PROBLEM TO BE SOLVED: To provide a travel section line recognition device that has a high recognition rate of a travel section line.SOLUTION: A travel section line recognition device (1) comprises: an image acquisition unit (3); a travel section line candidate extraction unit (5); a conviction level calculation unit (7); and a travel section line recognition unit (9) that recognizes as a travel section line a travel section line candidate in which a conviction level is equal to or more than a predetermined threshold. The travel section line recognition device further comprises: a travel lane information acquisition unit (13) that acquires travel lane information including the number and a width of travel lanes; a travel lane determination unit (15) that determines a travel lane on which a subject vehicle travels; and a travel section line position estimation unit (17) that estimates a position of a travel section line on the basis of the travel lane information. The conviction level calculation unit increases a conviction level of the travel section line candidate in a case where a distance between a position of the travel section line candidate and the estimated position of the travel section line is within a predetermined range.SELECTED DRAWING: Figure 1
【課題】走行区画線の認識率が高い走行区画線認識装置を提供すること。【解決手段】画像取得ユニット(3)と、走行区画線候補抽出ユニット(5)と、確信度算出ユニット(7)と、確信度が所定の閾値以上である走行区画線候補を走行区画線として認識する走行区画線認識ユニット(9)とを備え、走行レーンの数及び幅を含む走行レーン情報を取得する走行レーン情報取得ユニット(13)と、自車両が走行中の走行レーンを特定する走行レーン特定ユニット(15)と、走行レーン情報に基づき走行区画線の位置を推定する走行区画線位置推定ユニット(17)とを備え、確信度算出ユニットは、走行区画線候補の位置と、推定した走行区画線の位置との距離が所定範囲内である場合、その走行区画線候補の確信度を高くすることを特徴とする走行区画線認識装置(1)。【選択図】図1
