Adaptive fringe projection algorithm for 1-D MEMS projector

With the rapid development of structured light 3D imaging, one-dimensional MEMS mirrors, characterized by their small size and cost advantages, are extensively applied in structured light 3D imaging systems. In order to address the 3D imaging challenges on highly reflective surfaces with one-dimensional MEMS mirror projection modules, this paper proposes an adaptive projection method based on stripe edges. It can generate binary fringe patterns in highly reflective regions and phase-shift patterns in other regions, synthesizing them into a composite pattern for phase unwrapping. Additionally, to further improve the reconstruction accuracy, interpolation is applied to the phase map of the binary fringe pattern. Simulation experiments demonstrate that the proposed method can achieve accurate reconstruction on highly reflective surfaces.
