To reduce computational complexity in the case of detecting a line from an image including a travel path.SOLUTION: A line detection device 10 comprises a distribution information generating unit 140, an estimation information generating unit 160 and a specification processing unit 180. The distribution information generating unit 140 generates first distribution information which indicates distribution of pixels meeting the criteria on the basis of an image including a travel path on which a mobile body travels. The estimation information generating unit 160 selects, using the distribution information, first candidate pixels which are pixels estimated as a part of a line drawn on the travel path. The specification processing unit 180 specifies a first line included in an image on the basis of the positions of the first candidate pixels in the image.SELECTED DRAWING: Figure 1
【課題】走行路を含む画像から線を検出する場合において、演算量を少なくする。【解決手段】線検出装置10は、分布情報生成部140、推定情報生成部160、及び特定処理部180を備えている。分布情報生成部140は、移動体が走行する走行路を含む画像から、基準を満たす画素の分布を示す第1の分布情報を生成する。推定情報生成部160は、分布情報を用いて、走行路に描かれている線の一部と推定される画素である第1の候補画素を選択する。特定処理部180は、画像における第1の候補画素の位置に基づいて、画像に含まれる第1の線を特定する。【選択図】図1
