A human vision model is formulated in this paper, considering that line drawings are not limited to projection only from a polyhedron. To select a line drawing which can serve as an elementary picture for human stereo vision, we performed a psychological experiment. The model was proposed based on the experimental data to describe a property of human vision. Several examples were solved to validate the proposed model. The image-irradiate equation given by the Poisson equation is solved to reconstruct a face. Numerical simulation demonstrates that faces can be recovered precisely by considering the shading on the picture. This successful procedure involves solving the Dirichlet problem of the Poisson equation, specifying the boundary condition which is produced by the reconstructed edges. Numerical examples involve a drawing comprised only of lines, and a line drawing with shading.
