摘要

In the wrapped phase map of the 3D object containing the height discontinuities, this paper develops an enhanced noise detection scheme to enable the three types of noise, the speckle noise, the residual noise, and the noise at the lateral surface of height discontinuities, to be efficiently and simultaneously detected with a greater degree of precision. Since any threshold of this scheme is related to the number of noise and does not influence the phase jumps, the application with filtering operations enables the edges of the phase jumps without smearing and the application with the phase unwrapping algorithms enables the unwrapping path to avoid the positions of the noise, especially, at the height discontinuities.
