Abstract

This paper presents an approach for single-shot 3D shape reconstruction using a multi-wavelength array projector and a stereo-vision setup of two multispectral snapshot cameras. Thus, a sequence of six to eight aperiodic fringe patterns can be simultaneously projected at different wavelengths by the developed array projector and captured by the multispectral snapshot cameras. For the calculation of 3D point clouds, a computational procedure for pattern extraction from single multispectral images, denoising of multispectral image data, and stereo matching is developed. In addition, a proof-of-concept is provided with experimental measurement results, showing the validity and potential of the proposed approach.
