Background:

Conventional fringe projection techniques for 3D profile measurement rely on phase unwrapping, a computationally intensive and time-consuming process.
Existing methods often struggle with accuracy and speed due to the complexities of phase unwrapping.

Purpose of the Study:

To develop a phase unwrapping-free algorithm for 3D object profile measurement.
To enhance the efficiency and accuracy of 3D metrology using fringe projection.

Main Methods:

A novel algorithm based on the Fourier transform method is proposed.
Color fringe patterns are utilized instead of traditional gray-level patterns.
Intensity information extracts the wrapped phase, while color information determines the phase shift range.
