Accuracy analysis of different surface reconstruction modeling methods of heritage objects, digitalized according to photogrammetric data

Abstract

The possibilities of the heritage object reconstruction is explained in this article. The measurements were made using photogrammetric data received from the digital images. The digital images for the analysis were taken by the metric digital camera Canon EOS 1D Mark III. This camera has been calibrated in the Germany Bonn University in Institute of Photogrammetry. The images were taken with the Russian photogrammetric software PhotoMod. In the investigative objects there was made the TIN (Triangulated Irregular Network) and the orthophoto map. The TIN data modelling analysis was made using the ArcGIS software. The purpose of the article was to reconstruct the surface of the heritage objects from the photogrammetric data, to investigate accuracy dependence of the heritage objects reflection on the methods of initial data preparation, to evaluate the influence of modelling methods on to the accuracy of the heritage objects reconstruction. When modelling the photogrammetric data and selecting the most appropriate method of modelling parameters to restore the most accurate surface of the heritage object.
