To accurately detect, in the case of detecting a line from an image including a travel path, whether the line is a continuous line or a dotted line.SOLUTION: A line detection device 10 comprises a first detection unit 100 and a determination unit 300. The first detection unit 100 includes a specification processing unit. The specification processing unit processes a plurality of frame images which compose a video imaged by an imaging device held by a mobile body and including a travel path, so as to specify a line included in each of the frame images. The determination unit 300 determines a detection period of a line using respective processing results of the frame images from the specification processing unit, and determines whether the line is a dotted line or not.SELECTED DRAWING: Figure 17

    【課題】走行路を含む画像から線を検出する場合において、その線が連続線であるか点線であるかを精度よく検出する。【解決手段】線検出装置10は、第1検出部100及び判断部300を備えている。第1検出部100は特定処理部を有している。この特定処理部は、移動体に保持された撮像装置によって撮像され、走行路を含む動画を構成する複数のフレーム画像を処理することにより、フレーム画像のそれぞれに含まれる線を特定する。判断部300は、特定処理部によるフレーム画像のそれぞれの処理結果を用いて線の検出周期を判断し、前記線が点線であるか否かを判断する。【選択図】図17
