Abstract: In fringe projection profilometry (FPP), measuring accuracy is closely related to the fringe contrast ratio (CR). Especially for low-reflective scenes, fringe contrast being compressed ...

Implementing inline inspection and adaptive process control systems, supported by machine learning algorithms, can provide ...

Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman ...

Abstract: The structured light (SL)-based three-dimensional (3D) measurement techniques with deep learning have been widely studied to improve measurement efficiency, among which fringe projection ...
