A novel Structured Light method for one-shot dense reconstruction

摘要

Dense acquisition for moving scenarios represents an active field of research in Structured Light (SL). A common solution is to project a single one-shot fringe pattern, extracting depth from the phase deviation of the imaged pattern. This implies the use of a phase unwrapping algorithm, which can fail in the presence of depth discontinuities and occlusions. Our work presents a new one-shot dense pattern where De-Bruijn and Windowed Fourier Transform are combined obtaining a dense, absolute, accurate and computationally fast 3D reconstruction regarding the other existing techniques.
