Abstract
Provided is a machine tool including: an image acquiring unit that acquires an image of an imaging target; a movement mechanism that relatively moves the imaging target and the image acquiring unit; and a control unit, wherein the movement mechanism relatively moves the imaging target and the image acquiring unit by a known distance in an imaging direction of the image acquiring unit or in a direction substantially perpendicular to the imaging direction, and the image acquiring unit acquires images of the imaging target before and after the movement, and the control unit calculates a distance between the image acquiring unit and the imaging target in the imaging direction based on a movement distance or a length measured in the two acquired images. This enables distance measurement to be performed in a short time without making contact with an object to be measured.
