IMAGING DEVICE

WIPO Patent Application WO/2020/179746

A1

The purpose of the present invention is to provide an imaging device capable of efficiently acquiring an image suitable for analyzing a member gripped by a rotation part of a machine tool. Provided is a machine tool imaging device 2 comprising: an imaging unit 10 that is disposed in a region which does not rotate, and that images a member gripped by a rotation part of a machine tool; an imaging control unit 20 that acquires the rotation angle of the rotation part, and that controls the imaging unit so as to correspond to the rotation angle of the rotation part; an analysis image selection unit 30 that selects, from images acquired by the imaging unit, an analysis image suitable for analyzing the member; and an analysis rotation angle determination unit 40 that determines, from the rotation angle of the rotation part when the images were acquired by the imaging unit, an analysis rotation angle which is the rotation angle when the analysis image was imaged. In a first step, the imaging control unit 20 controls the imaging unit 10 to image the member gripped by the rotation part that has rotated so as to correspond to the rotation angle of the rotation part, and in a second step, the imaging control unit 20 controls the imaging unit 10 to image the member again at the analysis rotation angle.
