Background:

Phase unwrapping is crucial for 3D reconstruction but faces challenges with complex surfaces and motion blur.
Traditional temporal phase unwrapping algorithms (TPUAs) can suffer from order jumps, reducing accuracy.
Quality-guided phase unwrapping algorithms (QGPUAs) offer high accuracy but may struggle with complex data.

Purpose of the Study:

To propose a generalized spatial-temporal phase unwrapping algorithm (STPUA) for accurate absolute phase extraction.
To overcome the order jump issue in TPUAs while maintaining the high accuracy of QGPUAs.
To enable robust 3D reconstruction of isolated objects with intricate surfaces.

Main Methods:

Wrapped phase is divided into regional wrapped phases for successive unwrapping by QGPUAs.
Reliable points from fringe order maps are used to map regional unwrapped phases to absolute phase.
Combines spatial phase unwrapping algorithms (SPUAs) and TPUAs for enhanced performance.

Main Results:

The proposed STPUA effectively eliminates order jumps inherent in TPUAs.
Achieves high measuring accuracy comparable to QGPUAs.
Demonstrates high measuring robustness for complex surfaces and motion blur.

Conclusions:

The STPUA provides a robust and accurate method for absolute phase extraction.
The algorithm is suitable for real-time 3D reconstruction applications.
Experimental results validate the effectiveness and capability of the proposed STPUA.
