Abstract

A solution is given of the reconstruction problem of the vertex coordinates of a three-dimensional image of a 3D object in the shape of a polyhedron, situated on a plane. There were used the algorithms of contour analysis of the images of its perspective projections with a constant level of intensities (shadows). The conjugate points on these projections, necessary for the reconstruction, were obtained using the results of the contour coordinated filtration.
