Abstract
(EN) A line detection device (10) is provided with a first detection unit (100) and a second detection unit (200). The first detection unit (100) extracts, from an image including a travel path along which a moving body travels, pixels the color of which is within a predetermined range, and uses the distribution of the extracted pixels in the image to detect a line of a first color included in the image. After a first processing unit (100) has performed processing, the second detection unit (200) extracts, from the image, pixels the luminance of which is within a predetermined luminance range, and uses the distribution of the extracted pixels in the image to identify a line that is included in the image and that is of a second color different from the first color.
(FR) L’invention concerne un dispositif de détection de ligne (10) qui est pourvu d'une première unité de détection (100) et d'une seconde unité de détection (200). La première unité de détection (100) extrait, à partir d'une image comprenant un trajet de déplacement le long duquel se déplace un corps mobile, des pixels dont la couleur se situe dans une plage prédéterminée, et utilise la distribution des pixels extraits dans l'image pour détecter une ligne d'une première couleur comprise dans l'image. Après la réalisation d'un traitement par une première unité de traitement (100), la seconde unité de détection (200) extrait, à partir de l'image, des pixels dont la luminance se situe dans une plage de luminance prédéterminée, et utilise la distribution des pixels extraits de l'image pour identifier une ligne qui est incluse dans l'image et qui est d'une seconde couleur différente de la première couleur.
(JA) 線検出装置(10)は、第1検出部(100)及び第2検出部(200)を備える。第1検出部(100)は、移動体が走行する走行路を含む画像から、色が予め定められた範囲に位置する画素を抽出し、画像内における抽出した画素の分布を用いて画像に含まれる第1色の線を検出する。第2検出部(200)は、第1処理部(100)が処理を実行した後、画像から、輝度が予め定められた輝度範囲に位置する画素を抽出し、画像内における抽出した画素の分布を用いて、画像に含まれていて第1色とは異なる第2色の線を特定する。
