Measurement of the Helfenburk Castle near Úštěk and Creation of its Spatial model

Abstract

The main topic of this master’s thesis is measurement and creation of documentation of the Helfenburk Castel near Úštěk in northern Bohemia. Helfenburg is a ruin of the castle from the 14th century. It is made of sandstone and it is situated on a sandstone rock. The tower and the wall are well preserved. The main focus is on the inner part of the castle, although the whole castle including both sides of the wall was measured. Laser scanning was chosen as the most convenient way of data acquiring. The Trimble TX5 laser scanner was used for measuring. The resulting point clouds were processes in the Geomatic Studio and Cyclone. The final point cloud was transformed into the S-JTSK (Datum of Uniform Trigonometric Cadastral Network) coordinate system and the Bpv (Baltic After Adjustment) height system using geodetic network created at the castle by our group of students. The CAD 3D model of the inner castle part was created and edited in a specialized software: Cyclone, 3DReshaper and Microstation. A plan of the whole castle was drawn in a scale 1:250. The results of this work are a complete point cloud, a 3D model of the inner castle and a plan of the castle. They will serve as an accurate documentation of the current state, for the archeological research and for publication on the web of Helfenburk.
