Abstract:
(EN) Provided are a distance image processing device, a distance image acquisition device, and a distance image processing method, whereby a high-precision and high-visibility distance image can be acquired in the case of near distance measurement. The present invention is provided with a first distinguishing unit (52) for distinguishing between an abnormal pixel and a pixel having a distance value exceeding a certain distance range among a plurality of pixels of a distance image, a second distinguishing unit (54) for furthermore distinguishing the abnormal pixel distinguished by the first distinguishing unit (52) as a contiguous first abnormal pixel or a non-contiguous second abnormal pixel, and a clip processing unit (56) for changing the distance value of a first abnormal pixel to a certain value.
(FR) L'invention concerne un dispositif de traitement d'image de distance, un dispositif d'acquisition d'image de distance et un procédé de traitement d'image de distance, une image de distance à haute précision et à haute visibilité pouvant être acquise dans le cas d'une mesure de distance proche. La présente invention comprend une première unité de distinction (52) pour distinguer entre un pixel anormal et un pixel ayant une valeur de distance dépassant une certaine plage de distance parmi une pluralité de pixels d'une image de distance, une seconde unité de distinction (54) pour distinguer en outre le pixel anormal distingué par la première unité de distinction (52) en tant que premier pixel anormal contigu ou en tant que second pixel anormal non contigu, et une unité de traitement de séquence (56) pour modifier la valeur de distance d'un premier pixel anormal à une certaine valeur.
(JA) 近距離測定の場合に高精度且つ高視認性の距離画像を取得することができる距離画像処理装置、距離画像取得装置、及び距離画像処理方法を提供する。距離画像の複数の画素のうち一定の距離範囲を超えた距離値を持つ画素を異常画素と判別する第1の判別部(52)と、第1の判別部(52)により判別された異常画素を、更に連続している第1の異常画素と連続していない第2の異常画素とに判別する第2の判別部(54)と、第1の異常画素の距離値を一定値に変更するクリップ処理部(56)を備える。
