Abstract

Noncontact reconstructing 3-D objects surface profile on base of projection-shadow method is investigated in this paper. It is shown that this method in contrast to known techniques allows reconstructing a shape of object with vertical sides. Optimal parameters for measuring are proposed. The dependence of relative error of reconstructing on angle of light beam propagating is obtained.
