Abstract:Sinusoidal structured illumination is widely used in three-dimensional(3-D) sensing.Take phase-measuring profilometry for example,it is inherently free of errors only with perfect sinusoidal fringe projection.However,it is difficult to produce a perfect sinusoidal grating.Here we propose an error diffusion algorithm to produce a relatively accurate sinusoidal fringe projection and to improve the precision.Not only the error between the sinusoidal fringe produced with this means and the corresponding normati...
Keywords:phase-measuring profilometry  structured illumination  binary encode  error diffusion algorithm
