1. A shape measuring apparatus comprising:
- a probe having a gauge head configured to contact a measured object, the probe configured to move the gauge head within a predetermined area;
a mover configured to move the probe; and
a controller configured to control the mover, wherein;
a shape of the measured object is measured by moving the gauge head along a surface of the measured object while the gauge head is pressed against the measured object, and the controller comprises;
a contact point obtainer configured to obtain a contact point location of the surface of the measured object and the gauge head; and
a motion commander configured to calculate, based on the contact point location, a location command value of a speed vector causing the mover to move the probe along the surface of the object.

Abstract
A 3D measuring apparatus includes a probe that has a spherical gauge head for measuring a measured object; a motion mechanism that holds and moves the probe; and a motion controller that controls the motion mechanism. The controller includes a contact point obtainer that obtains a contact point location of a surface of the measured object and the gauge head based on a central location of the gauge head; a radius of the gauge head; and a swing amount of the gauge head. The controller also includes a motion commander that calculates a location command value causing the motion mechanism to move the probe, based on the contact point location obtained by the contact point obtainer.
