To accurately determine types of lines by a plurality of cameras.SOLUTION: A dividing line recognition device comprises: a plurality of cameras; a line type determination section for detecting dividing line candidates from each image obtained from the plurality of cameras and for determining the types thereof; a dividing line position calculation section for calculating positions for the detected dividing line candidates; a reliability calculation section for calculating the reliability of each dividing line candidate using positional relation among the detected dividing line candidates; a probability calculation section for computing the probability of each line type by being inputted with line types of the dividing line candidates whose reliability is equal to or greater than a threshold value; and a line type determination section for finally determining a line type for the dividing line on the basis of the result obtained from the probability calculation section.SELECTED DRAWING: Figure 2
【課題】複数カメラによる正確な線種判定を可能にする。【解決手段】複数のカメラと、前記複数のカメラで得られたそれぞれの画像から区画線候補を検知しその種類を判定する線種判定部と、検知された区画線候補の位置を算出する区画線位置算出部と、前記検知された区画線候補の位置関係を用いて各区画線候補の信頼度を計算する信頼度算出部と、前記信頼度が閾値以上の区画線候補の線種を入力として各線種の確率を求める確率計算部と、確率計算部の結果に基づいて当該区画線の線種を最終的に決定する線種決定部と、を備える。【選択図】図2
