Problems solved by technology
The Fourier method can demodulate the phase information from a fringe pattern, but due to the limitation of its calculation principle itself, it is always a difficult problem for how to accurately extract the frequency spectrum of the carrier, and the time-consuming calculation is also a problem of the Fourier transform method. Inherent problem
The phase shift method uses multiple phase images for measurement, but multiple images are not suitable for fast measurement, let alone complete dynamic measurement
However, in recent years, the phase unwrapping algorithm has not made a breakthrough

The invention provides a generative adversarial network acquisition method, a device and a system for phase unwrapping, a method for unwrapping a phase by using the network, a computer readable storage medium and a system. The network acquisition method comprises the following steps: acquiring a phase folding diagram; generating a phase unwrapping graph by using a generative network in the generative adversarial network; obtaining a real phase unwrapped graph; combining the generated phase unwrapped graph and the real phase unwrapped graph; using a discriminant network in the generative adversarial network to discriminate the authenticity of the combined result to obtain a classifier; when the probability that the corresponding pixel value is true is different from the probability that thecorresponding pixel value is false, calculating a loss value of the generative adversarial network according to the pixel value of the classifier, and optimizing model parameters of the generative adversarial network; and repeating the above steps until the probability that the corresponding pixel value is true is the same as the probability that the corresponding pixel value is false.
Description
technical field [0001] The present invention relates to the field of phase unwrapping, in particular to a method and device for acquiring a generative countermeasure network for phase unwrapping, a method for phase unwrapping based on a generative countermeasure network, a computer-readable storage medium, and a system . Background technique [0002] The rapid measurement of the three-dimensional shape of objects is widely used in industrial inspection, aerospace, medicine, cultural relics, education and other industries. In order to realize the rapid measurement of the three-dimensional shape of objects, the current mainstream method is to use non-contact measurement methods, among which phase measurement profilometry is a relatively mature method at present. In the field of phase measurement profiling, the quality of phase unwrapping results directly affects the accuracy of measurement results, so phase unwrapping technology plays an important role. [0003] The most com...
