The present invention addresses the problem of enabling an accurate determination of line type using a plurality of cameras. A demarcation line recognition device of the present invention includes a plurality of cameras (101); a line type determination unit (210) that senses demarcation line candidates from respective images obtained by the plurality of cameras and determines line types of the sensed demarcation line candidates; a demarcation line position calculation unit that calculates the positions of the sensed demarcation line candidates; a reliability level calculation unit that computes a reliability level of each demarcation line candidate by using positional relationships between the sensed demarcation line candidates; a probability computation unit (204) to which line types of demarcation line candidates for which the reliability level is equal to or greater than a threshold value are input and that determines the probability of each line type; and a line type decision unit (205) that finally decides the line types of the demarcation lines on the basis of the results of the probability computation unit.
