METHOD AND APPARATUS FOR MEASURING 3D SHAPE BY USING DERIVATIVE MOIRE |
| 摘要 |
The present disclosure provides an apparatus for measuring three-dimensional shapes by using moire interference, which comprises a unit calibration unit, an integrated calibration unit and a phase calibration unit. The unit calibration unit is configured to use a phase difference between two adjacent measuring points for obtaining a unit calibration value of an absolute moire order. The integrated calibration unit is configured to calibrate the absolute moire order up to a target point by using the unit calibration values. The phase calibration unit is configured to calibrate a phase of the target point by using the absolute moire order. |
