Summary: | 碩士 === 國立中興大學 === 機械工程學系所 === 96 === In this paper, we provide a new phase unwrapping method which based on adaptive parallel phase unwrapping method and image processing technique. According to the characteristics of adaptive parallel phase unwrapping method, the jump range of wrapped phase map will be found during unwrapping. Image processing technique, which includes component labeling, thinning, endpoint finding and morphological operators, are used to overcome the influence of noise and physical discontinuities in unwrapping processing. The new method not only fits the line of physical discontinuities in phase map, but also segments the wrapped phase map. In this new method, the unwrapping processing by regional unwrapping technique will be correct.
