Abstract
A correction value measurement method includes, measuring a position of a reference sphere, calculating a relative position of the reference sphere with respect to a sensing position from the position of the reference sphere, a length of the position measurement sensor, and a length of the reference tool. The method further includes acquiring a reference tool position as a distal end position of the reference tool using, calculating a length direction correction value of the position measurement sensor from the reference tool position, the position of the reference sphere, the relative position, and a length of the reference tool, and measuring the position of the reference sphere to calculate a radial direction correction value of the position measurement sensor.
