Patent ID: 8543352

Claim:
A system for measuring a shape, comprising: an external storage unit configured to store tolerances of first and second shape factors, the first and second shape factors defining a design shape of a measuring object; a first measuring tool configured to measure the first shape factor of the measuring object by obtaining position coordinates of peripheral edges of the measuring object and to obtain measurement data; and a measurement processing unit configured to determine a shape of the measuring object, the measurement processing unit includes; a comparison module configured to compare the measurement data of the first shape factor with the tolerance of the first shape factor stored in the external storage unit; a verification module configured to compose a predicted shape using the measurement data when the measurement data is in a range of the tolerance of the first shape factors, and to verify whether the predicted shape is formed as a figure corresponding to the design shape; a calculation module configured to calculate predicted data of the second shape factor from the predicted shape normally composed by the verification module; and a determination module configured to determine a measurement shape by comparing the predicted data calculated by the calculation module with the tolerance of the second shape factor stored in the external storage unit wherein the predicted data of the second shape factor reduces an error in the measurement data of the first shape factor.
