System for measuring a shape, method for measuring a shape, and computer program product

A non-transitory computer-readable medium encoded with a computer program for causing a computer to measure a shape comprising:

• obtaining first measurement data of a first shape factor measured from a measuring object by obtaining position coordinates of peripheral edges of the measuring object by a first measuring tool using an input module of a measuring process unit of the computer, the first shape factor and a second shape factor defining a design shape of the measuring object;
• comparing the first measurement data with a tolerance of the first shape factor in a comparison module of the measuring unit of the computer, the tolerance of the first shape factor retrieved from an external storage unit of the computer;
• when the first measurement data is within a range of the tolerance of the first shape factor forming a first predicted shape horn the first measurement data and verifying that a first predicted shape is formed as a figure in a verification module of the computer;
• when the first predicted shape is formed as a figure calculating first predicted data of the second shape factor from the first predicted shape using a calculation module of the computer, the second shape factor differing from the first shape factor;
• and
• when the first predicted data is within a range of a tolerance of the second shape factor determining the first predicted shape as a first measurement shape
• wherein first predicted data of the second shape factor reduces an error in the first measurement data of the first shape factor.
