Frequency-division-multiplexing based period-coded fringe pattern for reliable depth sensing
Abstract The fringe pattern can realize high-resolution and dense depth sensing.However, the phase ambiguity is a challenge in the fringe pattern.In this paper, one period-code pattern is embedded to the fringe Cropped Oversized Button Up pattern by the frequency-division-multiplexing (FDM) framework.The nonparametric skew and De Bruijn sequence ar
