Method of calibrating a scanning system
First Claim
1. A method of measuring an object using a surface sensing device mounted on a coordinate positioning apparatus, the method comprising:
- (a) measuring a single surface point of a feature of the object with the surface sensing device;
(b) moving the surface sensing device along a path around the feature at a fast speed, thereby taking measurements along the path, including at the surface point;
(c) determining the difference between the measurement of the surface point in step a) and in step b); and
(d) using the difference determined in step c) to apply a correction to the object or subsequent objects having the same feature.

Abstract
A method of measuring an object using a surface sensing device mounted on a coordinate positioning apparatus. The method has the steps of measuring a single surface point of a feature of the object with the surface sensing device, moving the surface sensing device along a path around the feature at a fast speed, thereby taking measurements along the path, including at the surface point, determining the difference between the measurements of the surface point and using the difference determined to apply a correction to the object or subsequent objects having the same feature.
