PRECISION ASSURANCE FIXTURE FOR CCD CAMERA-BASED THREE-DIMENSIONAL SHAPE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a measurement precision assurance fixture capable of shortening largely measurement precision guarantee time of a CCD camera-based three-dimensional shape measurement device. SOLUTION: In a precision assurance fixture body 1 is equipped with a focal adjustment section 2 for CCD camera focusing and precision assurance shaped sections 3a to 3d and 4a to 4d at the outermost part of the total measurable area, difference between the three-dimensional data created from the measurement data measured by a precision guarantee contact-type three-dimensional shake instrument and the measured point group data of the measurement precision assurance fixture measured by the CCD camera-based three-dimensional shape measurement device is calculated to implement precision guarantee of CCD camera-based three-dimensional shape measurement device.
