Abstract: According to the present invention, a center deviation amount, which is an amount of deviation (distance) between the center line of a reference measurement target and the detection point is calculated using the reference measurement target having a known diameter, and a measurement value of a diameter of an arbitrary measurement target is corrected using the center deviation amount. Therefore, an accurate diameter value can be calculated even in the case of a measurement target having a diameter value different from the diameter value of the reference measurement target.
