PROBLEM TO BE SOLVED: To provide a traffic lane identification device that improves accuracy of a straight line detection.SOLUTION: A traffic lane identification device comprises: a straight line detection unit that extracts a plurality of lines defining a traffic lane of a road from an image and performs a Hough transformation to each of the lines; a first tournament processing unit that divides a Hough space obtained by the Hough transformation for each prescribed angle, detects the number of respective votes with respect to a plurality of intersections of a Hough curve in the Hough space divided for each prescribed angle, and identifies the intersection in which the number of votes is topped; and a second tournament processing unit that selects a prescribed number of intersections in descending order of the number of votes out of the intersections having the number of votes topped, and thereby identifies a plurality of approximation straight lines approximate to each of the plurality of lines. The plurality of identified approximation straight lines are identified as the traffic lane. |
