Pashchetnyk O. Developing and researching of ways to determine the elements of interior orientation of unmetrical digital survey cameras

Object of research - unmetrical digital survey cameras. Purpose - to study the impact of internal orientation elements errors in shortbasis stereophotogrammetry survey on accuracy of points on objects spatial coordinates and developing of ways to determine the interior orientation elements of unmetrical digital survey cameras. Methods - methods of mathematical analysis, differential calculus, the theory of errors and mathematical modeling. Theoretical and practical results, novelty - the analysis of accuracy of determination the objects points coordinates in short basis stereophotogrammetry survey, the limits of error of interior and exterior orientation elements at short basis survey is set and their impact on the results of measuring of objects points spatial coordinates is determined; enabled a priori estimation of accuracy of main point coordinates and focal distance for unmetrical digital survey cameras (Canon EOS 350D, Canon EOS 450D and Canon EOS 5D Mark II); developed and researched three ways to determine elements of interior orientation (main point coordinates, focal distance, equivalent zoom lens focal distance) for unmetrical digital survey camera's, that are sold based on existing and widely used in topographic and geodetic (photogrammetric) production of standardized devices and appliances. The research results can be used to calibrate unmetrical digital cameras that are used for removing short basis survey in various fields of science and engineering (architectural measurements, the study of engineering structures deformations, structures microscopy geological elements, in art restoration work, criminology, in engineering and surveying work in medicine, etc.).
