In this paper the method of statistical few view reconstruction of the geometrical characteristics of three-dimensional convex objects of irregular shape which are approximated by an ellipsoid of General form is under consideration. The statistical reconstruction is carried out with the usage of the basic features of a triad of its mutually orthogonal two-dimensional discrete projection images. The areas of two-dimensional projection images of an object and its linear sizes of one-dimensional projection images are taken as the basic characteristics. While describing an object sizes, we consider that the spatial geometrical characteristics of an object are its linear (dimensional) sizes and the average projected diameter of a three-dimensional image of an ellipsoid of General form, which approximates this object. While describing the object shape, we consider that the spatial geometrical characteristics of an object are represented by the coefficient of asphericity that is determined as the ratio of the maximum and minimum dimensions (axes) of the approximating ellipsoid.
