Abstract
In this paper we proposed a method for three-dimensional (3D) shape measurement and visualization of balloon hull during quick deflation based on Fourier transform profilometry (FTP). A sequence of dynamic deformed fringe images can be grabbed by high-speed CCD camera and saved on disk rapidly. By Fourier transform, filtering, inverse Fourier transform and unwrapping these phase maps in 3D phase space, we can obtain the shape of the rapid deflating balloon in different times. Based on the phase difference between two neighborhood frames, we propound a 3D phase unwrapping algorithm, which will be of great benefit to 3D phase unwrapping in speed and accuracy. The results of our experiment indicate that the method, presented in this paper, can efficiently deal with the surface shape measurement for rapid motion object and will be a promising one with the development of high-speed frame grabber.
