Modeling of Sacral Objects Made on the Basis of Aerial and Terrestrial Laser Scanning

In the publication, the authors demonstrated the possibility of using terrestrial and airborne laser scanning technology for both inventory and modeling of architectural objects. First of all, they presented the use of laser scanning technology, for creation of 3D models of sacral objects, both the large ones, as well as the smaller ones constituting small architecture objects. For the airborne laser scanning, the subject of the study was the Sanctuary of the Divine Mercy in Krakow along with the surrounding complex of sacral buildings. Modelling and visualization of the Sanctuary were made in the TerraSolid and MicroStation programs on the basis of a point cloud with a density of 12 points/m2. Data from terrestrial laser scanning were obtained on the basis of measurement with the use of terrestrial laser scanner Leica ScanStation P40 and included the Chapel of Our Lady of Czestochowa located in the Lasek Mogilski in Krakow.

I. Introduction

The technological progress at the end of the 20th century caused that the old and inconvenient methods of gathering geospatial information were replaced by modern technology that completely revolutionized the work of engineers. This technology includes laser scanning. Currently, the terrestrial and airborne laser scanning is the most modern and the most convenient form of data collection, and they owe their popularity primarily to the efficiency and high accuracy of the development compared to previously used measurement methods.
