THE USE OF THREE-DIMENSIONAL SCANNING AS METHODOLOGY OF 3 D LASER SCANNING AT CAVES' SURVEYING. PRESENTATION AT AGIOS GEORGIOS CAVE OF KILKIS
Abstract
The systematic study of the caves demands the existence of a reliable and detailed background at a suitable form and scale so as to satisfy any cognitional subject of the geosciences (geology, speleology, paleontology, statics, e.t.c). The composite geometry as well as the complexity of the schematisms is the main characteristics that make recording, surveying and validation of a cave an especially difficult procedure. The faddish conditions that are carried out at caves make the classical - traditional surveying methods (topography - photogrammetry) time consuming and unprofitable procedures. The use of three-dimensional scanning is not only an alternative methodology but also a significant tool at caves' surveying. With this up-to-date method there can be produced very fast 3D digital models of high accuracy, easy modeled, cost effective comparatively to the classic surveying methods. With the 3D laser scanner the three dimensions of the surfaces are determined and represented as a point-cloud. During the scanning thousands of separate 3D points are measured and the 3D model of the scan is represented in real-time. Additionally, by the recording of the intensity of the reflected radiation, useful information can be obtained for the texture of the surface. This paper deals with the study of the capabilities and the preconditions for the usage of the methodology of 3D laser scanning at caves' surveying. A case study of this methodology is represented that took place at a part of Agios Georgios cave , Kilkis region.
