Dynamic Three-Dimensional Surface Reconstruction Approach for Continuously Deformed Objects

Blog Article

For dynamic three-dimensional (3-D) surface reconstruction of continuously deformed objects, an efficient method employing one fringe pattern is proposed.First, a two-dimensional wavelet transform profilometry (2-D WTP) employing an improved cost function is adopted to obtain the wrapped phase, which has the better noise suppression ability.Then, a new 3-D phase unwrapping algorithm is introduced to obtain the unwrapped grand love red heart reposado tequila phase, which includes four steps.

a) A new 3-D residues recognition method is proposed.b) A 3-D branch cut construction algorithm based on an improved GA is proposed.c) A 3-D phase derivative variance quality map is established.

d) A 3-D flood filling phase unwrapping algorithm guided by 3-D quality map avoiding 3-D branch cut (3-D FGQAB) is introduced to obtain the unwrapped phase.Simulation and experimental comparisons are carried out, the results read more show that the proposed method can be applied to dynamic 3-D reconstruction of the continuously deformed objects.
