Learning-based 3D imaging from single structured-light image

Abstract

Integrating structured-light technique with deep learning for single-shot 3D imaging has recently gained enormous attention due to its unprecedented robustness. This paper presents an innovative technique of supervised learning-based 3D imaging from a single grayscale structured-light image. The proposed approach uses a single-input, double-output convolutional neural network to transform a regular fringe-pattern image into two intermediate quantities which facilitate the subsequent 3D image reconstruction with high accuracy. A few experiments have been conducted to demonstrate the validity and robustness of the proposed technique.
