After a hard research & develop activity it could be stated as the pioneer of this interesting field I reached usable and applicable results in connection with the 3D measurement and visualization of the caves.
I successfully developed basically new measurement methods which gives accurate and realistic models. The first method, called 4P2 is an easy way of extending previous maps with 3 dimensional visualization. The following method, the NP2, which is the extension of 4P2, is a technique based on segments which makes it possible to measure the passages of the caves quickly and homogeneous. The last method, SPCR is an adaptive surface reconstruction algorithm, which does not limit the number and the structure of the measured points. It allows creating regular and conformal surface model from a sparse and non-uniform point cloud which does not contain any holes and all the measured points are represented in it.
For the processing of the measured data and for the visualization of the generated surface model I developed two softwares names Torus and Toroid. Torus is developed for the desktop computers while Toroid is the version of Torus, which can be used in caves. Toroid is an Android application which permits of the usage of an Android based table or smartphone in caves.
I got the opportunity to test the new methods in Hungarian caves (Pálvölgyi-Mátyás-hegyi cave system, Szemlő-hegyi cave, Meta-cave). It was proved after the tests that the new 3D methods developed by me are applicable in real environments.
As a result of my work people who haven’ t got the opportunity to visit any caves, get the possibility to view the beautiful and unknown world of the caves. If we publish these new methods and softwares to everybody the human kind can realize that the caves are the nature’s beautiful pearls which must be respected and protected.
