Description
Summary:In aeronautics, engineering, medicine, robotics and other industries, optical methods are widely used to measure the geometry and surface deformation of various objects from their images. These methods are based on digital image processing algorithms and can be summarized in a group of methods called close-range photogrammetry. When developing photogrammetric measurement systems, one of the problems to be solved is the estimation of their error. In this work, it is proposed to use physical simulation to estimate the error, which gives more reliable results than theoretical calculations or computer simulation. The phasogrammetric method has been chosen as the reference method for surface shape measurement. This paper presents the results of the development of an optical phasogrammetric measurement system based on the structured illumination method and an evaluation of its accuracy characteristics.
