NON-CONTACT TYPE DISTORTION MEASURING APPARATUS, AND NON-CONTACT TYPE DISTORTION MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a non-contact type distortion measuring apparatus, and a non-contact type distortion measuring method for accurately measuring a predetermined physical amount regarding distortion of a specific area when the distortion is concentrated on the area in a test piece.;SOLUTION: The present invention includes: an imaging part 3 which captures an image of a test piece 2 to be measured; and physical amount derivation parts 50, 50B which detect an area Ar on which distortion is concentrated in the test piece 2 from image data on the test piece 2 acquired by the imaging part 3, to calculate predetermined physical amounts ε, ε_w regarding the distortion of the test piece 2 in the area Ar.;COPYRIGHT: (C)2014,JPO&INPIT
