Coding-Net: A multi-purpose neural network for Fringe Projection Profilometry

Fringe Projection Profilometry is one of the important techniques in three-dimensional vision. However, traditional Fringe Projection Profilometry employing a lot of patterns has significant challenges for efficiently recovering the absolute phase. In this paper, a multi-purpose neural network combining with code-based patterns is proposed to recover the absolute phase firstly, which can greatly decrease the number of patterns with high accuracy. Different from the traditional approach of trigonometric calculation, the well-trained multi-purpose network can learn the principle of extracting absolute phase from few patterns. Experiments demonstrate that the proposed method can acquire high accuracy for complex texture objects, indicating potential application in precision engineering with high speed.

Automated summary

A multi-purpose neural network combined with code-based patterns is proposed to efficiently recover absolute phase and decrease pattern quantity, showing potential for high accuracy in complex texture objects.
