Paper Abstract
This work presents a scanning deflectometric approach to solving a 3D surface reconstruction problem, which is based
on measurements of a surface gradient of optically smooth surfaces. It is shown that a description of this problem leads
to a nonlinear partial differential equation (PDE) of the first order, from which the surface shape can be reconstructed
numerically. The method for effective finding of the solution of this differential equation is proposed, which is based on
the transform of the problem of PDE solving to the optimization problem. We describe different types of surface
description for the shape reconstruction and a numerical simulation of the presented method is performed. The
reconstruction process is analyzed by computer simulations and presented on examples. The performed analysis
confirms a robustness of the reconstruction method and a good possibility for measurements and reconstruction of the 3D shape of specular surfaces.
