Abstract
(EN)
An image processing device according to the present disclosure is an image processing device including a tubular portion which is installed between an object and a sensor that captures an image of the object, the image processing device comprising: an acquisition unit which acquires a first image obtained from reflected light of light emitted from a point light source to the object and a second image obtained from reflected light of light emitted to the object from a light source other than the point light source; and a calculation unit which calculates shape information, that is information about the shape of the surface of the object, on the basis of the length of the tubular portion, the first image, and the second image.
(FR)
La présente invention concerne un dispositif de traitement d'image comprenant une partie tubulaire qui est installée entre un objet et un capteur qui capture une image de l'objet, le dispositif de traitement d'image comportant: une unité d'acquisition qui acquiert une première image obtenue à partir de la lumière réfléchie d'une lumière émise en provenance d'une source lumineuse ponctuelle vers l'objet et une seconde image obtenue à partir de la lumière réfléchie de lumière émise vers l'objet en provenance d'une source lumineuse autre que la source lumineuse ponctuelle; et une unité de calcul qui calcule des informations de forme, qui sont des informations concernant la forme de la surface de l'objet, en se basant sur la longueur de la partie tubulaire, la première image et la seconde image.
