Abstract: front page image
(EN)The present invention relates to a precision measurement system using an interferometer and an image, comprising: an interferometer for measuring a distance to a movable object by a transfer device; an imaging device which is fixed at a specific position and captures an image of an object located within a specific range; and a control device which calculates absolute coordinates indicating a distance from a reference point to each pixel of the image on the basis of the distance measured by the interferometer and the image obtained by the imaging device, calculates an absolute distance between the pixels of the image on the basis of the absolute coordinates, and measures a length of the object captured by the imaging device using the absolute coordinates or the absolute distance.
(FR)La présente invention concerne un système de mesure de précision utilisant un interféromètre et une image, comprenant : un interféromètre destiné à mesurer une distance par rapport à un objet mobile par un dispositif de transfert ; un dispositif d'imagerie fixé à une position spécifique et capturant une image d'un objet situé dans une plage spécifique ; et un dispositif de commande qui calcule des coordonnées absolues indiquant une distance entre un point de référence et chaque pixel de l'image sur la base de la distance mesurée par l'interféromètre et de l'image obtenue par le dispositif d'imagerie, calcule une distance absolue entre les pixels de l'image sur la base des coordonnées absolues, et mesure une longueur de l'objet capturée par le dispositif d'imagerie à l'aide des coordonnées absolues ou de la distance absolue.
(KO)본 발명은 간섭계와 영상을 이용한 정밀 측정 시스템에 관한 것으로서, 이송장치에 의하여 이동 가능한 물체와의 거리를 측정하는 간섭계; 특정위치에 고정되어 특정 범위 내에 위치하는 물체의 영상을 촬영하는 영상 장치; 및 상기 간섭계에 의하여 측정된 거리 및 상기 영상장치에 의하여 획득된 영상을 기초로, 기준지점으로부터 상기 영상의 각 픽셀까지의 거리를 나타내는 절대좌표를 산출하고, 상기 절대좌표를 기초로 상기 영상의 픽셀들간의 절대거리를 산출하고, 상기 절대좌표 또는 절대거리를 이용하여 상기 영상장치에 의하여 촬영된 상기 물체의 길이를 측정하는 제어장치를 포함한다.
