Phase-correlation application in three-dimensional reconstruction of large-size object

More Information
  • A three-dimensional reconstruction method of large-size object was presented. A sinusoidal grating was projected to the surface of the object, and a deformed fringe intensity image of sub-region was collected through the camera. Correlation algorithm was used to confirm the accurate overlapped area of the sub-region images, and a deformed fringe intensity image of the object was obtained by splicing. The object-s three-dimensional image was obtained by Fourier transform profilometry, and the experimental results was presented.
