Discrete cosine transform-based shift estimation for fringe pattern profilometry using a generalized analysis model.
What is believed to be a new analysis algorithm to carry out profile measurement with low computational complexity and less noise sensitivity is presented. First, a discrete cosine transform (DCT)-based representation method is introduced to express the height distribution of a 3D surface. Then a novel shift estimation algorithm, called the DCT-based shift estimation (DCT-SE), is presented to r...
متن کاملDiscrete-Cosine/Sine-Transform Based Motion Estimation
A new motion estimation scheme, Discrete-Cosine/SineTransform Based Motion Estimation (DXT-ME) utilizing the principle of orthogonality of cosine and sine functions to estimate, in the transform domain, displacements from the motion information contained in the pseudo-phases of the images of moving objects, is proposed. The computational complexity of this method is only O ( N 2 ) + O d c t for...
متن کاملSpatial shift unwrapping for digital fringe profilometry based on spatial shift estimation
An approach is presented to solve the problem of spatial shift wrapping associated with spatial shift estimation-based fringe pattern profilometry (FPP). This problem arises as the result of fringe reuses (that is, use of fringes with periodic light intensity variance), and the spatial shift can only be identified without ambiguity within the range of a fringe width. It is demonstrated that the...
متن کاملDigital fringe profilometry based on triangular fringe patterns and spatial shift estimation
In this paper, we present a new approach for the 3D measurement using digital fringe projection. Instead of sinusoidal fringe patterns and the traditional phase shift detection, the proposed technique makes use of triangular patterns and the spatial shift estimation for extract the 3D shape. The proposed technique is advantageous not only by improved immunization to nonlinear distortion associa...
