Embodiment Construction
[0041] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention is not limited thereto.
[0042] The phase diagram of the package to be unfolded is as follows: figure 2Shown is a wrapped phase map of a helical shear surface, with an image size of 257×257 pixels. It contains two planes that are entangled with each other and inclined to each other. The contour discontinuity between the two planes constitutes the boundary of the spiral shear. This wrapped phase map can be used to test the ability of the phase unwrapping method to handle complex contour discontinuities.
[0043] Firstly, the isolated noise pixels are removed from the wrapped phase image, and the specific process is as follows:
[0044] (1) According to the formula
[0045] v m , n = Int ...
