Abstract
(EN)
An imaging device 10 is provided with: a camera; an illuminator that is able to selectively irradiate an imaging object of the camera 22 with first illumination light 12s linearly polarized in a first direction and second illumination light 12p linearly polarized in a second direction orthogonal to the first direction; an image acquisition unit that acquires, from the camera 22, a first image including the imaging object irradiated with the first illumination light 12s and a second image including the imaging object irradiated with the second illumination light 12p; and an image processing unit that, on the basis of the first image and the second image, determines whether or not a linear polarizer is included in the imaging object.
(FR)
La présente invention concerne un dispositif d'imagerie 10 qui est pourvu : d'une caméra ; d'un illuminateur qui peut irradier sélectivement un objet d'imagerie de la caméra 22 avec une première lumière d'éclairage 12s linéairement polarisée dans une première direction et avec une seconde lumière d'éclairage linéairement polarisée dans une seconde direction orthogonale à la première direction ; une unité d'acquisition d'image qui acquiert, à partir de la caméra 22, une première image comprenant l'objet d'imagerie irradié avec la première lumière d'éclairage 12s et une seconde image comprenant l'objet d'imagerie irradié avec la seconde lumière d'éclairage 12p ; et une unité de traitement d'image qui détermine, sur la base de la première image et de la seconde image, si un polariseur linéaire est inclus ou non dans l'objet d'imagerie.
(JA)
撮像装置10は、カメラと、第1方向に直線偏光された第1照明光12sと、第1方向と直交する第2方向に直線偏光された第2照明光12pとをカメラ22の撮像対象に向けて選択的に照射可能な照明装置と、第1照明光12sが照射された撮像対象を含む第1画像と、第2照明光12pが照射された撮像対象を含む第2画像とをカメラ22から取得する画像取得部と、第1画像および第2画像に基づいて撮像対象に直線偏光子が含まれるか否かを判定する画像処理部と、を備える。
