Abstract:
A measuring apparatus comprising a first universal joint, a first fixing member to which the first universal joint is attachable, a table that is mounted on a base, to which the first fixing member is attachable and that is arbitrarily positionable on a plane, a driving device for driving the table for positioning, a detecting device for detecting a position of the table, a second universal joint, a second fixing member that is attached to an object to be measured and to which the second universal joint is attachable, and a measuring device that is selectively attached between each of the first universal joint that is attached to the table by means of the first fixing member and the second universal joint that is attached to the object to be measured by means of the second fixing member, wherein a position of the object to be measured with respect to the base is measured by positioning the first universal joint at least at three points by moving the table and measuring distances between the first universal joint at the respective positions and the second universal joint.
