MODELLING OF A HERITAGE PROPERTY USING A VARIETY OF PHOTOGRAMMETRIC METHODS

Abstract

In recent years, 3D modelling of historic heritage properties is most often based on photogrammetric measurements. Data on such properties can be obtained, however, by a variety of entirely different methods. This publication presents an example of developing a 3D model of a historic heritage building using two photogrammetric methods. The first one was based on photographs taken with a nonmetric camera, and the second one was based on data from terrestrial laser scanning. The object of the study was the Museum of the Estreicher Family in Krakow. The photos were obtained with a Canon EOS 400D DSLR camera and a cloud of points from terrestrial laser scanning with a Leica ScanStation P40 scanner. The development of the 3D model based on photographs was carried out using the Bentley ContextCapture software application, and the Agisoft PhotoScan Professional. In contrast, TLS (Terrestrial Laser Scanning) data was processed in the Leica Cyclone software application and modelled in the 3DReshaper. Both methods were analysed and compared in a tabular presentation.
