Improving the accuracy of determining the position of the code marks in the problems of constructing three-dimensional models of objects

摘要

The authors propose configuration of a code mark. It is part of the photogrammetric system and consists of two parts: identifying and measuring ones. These parts determine the mark ID, mark reference coordinate system and contain a set of circular retroreflective elements. Sources of measurement errors of geometric parameters of the code marks elements are considered. Authors have proposed the methods and algorithms for determining these parameters. These algorithms are used in constructing three-dimensional models of real objects.
