Characteristic features of geometric modeling of lost architectural monuments

Characteristic features of lost architectural works’ modeling with the help of iconographic materials are described in the article. In-depth analysis of the factors affecting its accuracy and possible ways of its accuracy improvement are presented. One method involves replacement of ideal geometric elements and concepts by fuzzy variables and probabilistic elements. The point in this case is an elliptical area, the center of which is its nominal position, and the border - defined error described by a normal distribution. The modification takes into account the probability of projective geometry properties of geometric information and fuzzy character sets. Based on the theory of measurement technique geometric modeling of lost architectural objects by iconographic materials is offered. A suggested modeling is based on a statistical analysis of the results obtained by fuzzy projective geometry, which in turn is based on the theory of fuzzy sets.
