    Abstract: A shape measuring device includes a holding unit which holds a measuring target of which a shape is to be measured, a first measurement unit which measures relative coordinates of a plurality of measurement points on a first surface of the measurement target with respect to a defined point, a second measurement unit which operates independently from the first measurement unit and measures relative coordinates of a plurality of measurement points on a second surface of the measurement target, which is a reverse surface of the first surface, with respect to the defined point, and a calculation unit which calculates a shape of the measurement target on the basis of results measured by the first measurement unit and the second measurement unit.

    CPC classification number: G01B11/03

    Abstract: Provided is an image measurement system including: a placement portion on which a measurement object is placed; an imaging unit configured to be relatively movable with respect to the placement portion; a movement control unit that switches between a high-speed movement mode and a low-speed movement mode and allows the imaging unit to relatively move with respect to the placement portion; and an imaging control unit that captures instantaneous image information by the imaging unit on the basis of switching to the low-speed movement mode.

    Abstract: A measuring apparatus of the present invention includes a stage on which a measured object is placed, a measurement head having an information obtainer obtaining an image of the object, and a vertical driver supporting the measurement head so as to allow movement in a vertical direction. The vertical driver includes a counterbalance mechanism having a hanger of the measurement head, a pulley winding up and withdrawing the hanger by rotation, a spring increasing elastic force by stretching the spring when the measurement head displaces downward, and a cam rotating in conjunction with the pulley and having a cam shape decreasing rotational torque provided to the pulley by the elastic force as a stretching amount of the spring increases.
