Abstract


  • In this paper, we present a new approach for the 3D measurement using digital fringe projection. Instead of sinusoidal fringe patterns and the traditional phase shift detection, the proposed technique makes use of triangular patterns and the spatial shift estimation for extract the 3D shape. The proposed technique is advantageous not only by improved immunization to nonlinear distortion associated with digital projections, but also reduced computational burden for its implementation. Theoretical analysis and experimental results are also presented to confirm the effectiveness of the proposed technique.
