  • Publication number: 20120194651
    Abstract: [PROBLEMS] To provide a shape measuring apparatus having a configuration which enables the operation for aligning a measuring probe and a candidate object to be simplified when the shape of the candidate object is measured. [MEANS TO SOLVE THE PROBLEMS] A shape measuring apparatus is configured so that an optical probe 20 moves relative to a candidate object, and the three-dimensional shape of the candidate object is measured without contact from information obtained by the optical probe 20. The shape measuring apparatus includes a gantry structure 10 allowing the optical probe 20 to be moved to a predetermined position relative to the candidate object, and a support device 30 allowing the candidate object to be rotated around at least two rotational axes.
