Patent ID: 7812969

Claim:
A three-dimensional shape measuring apparatus, comprising: a measuring section, adapted to be provided with three-dimensional measurement dimensions, for measuring a three-dimensional shape of a measurement object in a non-contact state, the measuring section adapted to measure a three-dimensional shape of a part of the measurement object multiple times by shifting the measurement dimensions to obtain a plurality of three-dimensional measurement data, the measurement dimensions being shifted in such a manner that at least portions of consecutive measurement dimensions by the shifting are lapped one over the other; and a data integrating section for integrating measurement data of parts of the measurement object to obtain the three-dimensional shape of the measurement object, wherein the data integrating section is configured to: receive the plurality of measurement data and a plurality of reliability information, each one of the plurality of measurement data associated with a corresponding one of the plurality of reliability information, wherein the reliability information is based on information selected from the group consisting of focus positions, focal lengths, focal displacement amounts, focal points, calibration distances, and measurement error; select the one of the plurality of measurement data having the highest reliability information associated with the respective measurement data as a selected measurement data for the part of the measurement object; and execute the data integration using the selected measurement data for each part of the measurement object.
