AB  - Three-dimensional (3D) shape measurement with fringe projection technique and 
      vertical scanning setup can alleviate the problem of shadow and occlusion. 
      However, the shape-from-defocus based method suffers from limited sensitivity and 
      low signal-to-noise ratio (SNR), whereas the projection-triangulation based is 
      sensitive to the zero-phase detection. In this paper, we propose paraxial 3D 
      shape measurement using parallel single-pixel imaging (PSI). The depth is encoded 
      in the radial distance to the projector optical center, which is determined by 
      the projection of light transport coefficients (LTCs). The third-order polynomial 
      fitting is used for depth mapping and calibration. Experiments on 5 objects with 
      different materials and textures are conducted, and standards are measured to 
      test the accuracy. The results verified that the proposed method can achieve 
      robust, dense reconstruction with depth accuracy at 20 mum while the 
      root-mean-square error (RMSE) of plane fitting up to 43 mum.
