Abstract

Wave unwrapping is an important part of fringe analysis. However, the ultimate result of wave unwrapping is usually impaired by bad data and noise from the phase shifting procedure. This paper presents a robust improved algorithm of region growing, which combines the procedure both of error point seeking and of region growing and ultimately gains a perfect wave unwrapping result. The whole processing is illustrated with images and charts obtained by both the computer simulation and practical operation.
