To accurately detect a line of a specific color from an image including a travel path.SOLUTION: A line detection device 10 comprises a first detection unit 100 and a second detection unit 200. The first detection unit 100 processes an image including a travel path on which a mobile body travels so as to detect a line of a first color included in the image. The second detection unit 200 extracts pixels which meet the criteria with predetermined luminance and, on the basis of positions of the extracted pixels in an image, detects a line of a second color included in the image. The second detection unit 200 defines the criteria using luminance of the line of the first color detected by the first detection unit 100.SELECTED DRAWING: Figure 13

    【課題】走行路を含む画像から特定の色の線を精度よく検出できるようにする。【解決手段】線検出装置10は、第1検出部100及び第2検出部200を備えている。第1検出部100は、移動体が走行する走行路を含む画像を処理することにより、当該画像に含まれる第1色の線を検出する。第2検出部200は、輝度が予め定められた基準を満たす画素を抽出し、抽出した画素の画像内における位置に基づいて、画像に含まれる第2色の線を検出する。第2検出部200は、上記した基準を、第1検出部100が検出した第1色の線の輝度を用いて定める。【選択図】図13
