Abstract: [eng] [cze]
Most current algorithms typically lack in robustness to noise or do not handle T-shaped curve joining properly. There is a challenge to not only detect features in the noisy 3D-data obtained from the digital scanners. Moreover, most of the algorithms even when they are robust to noise, they lose the feature information near the T-shaped junctions as the triplet of lines ``confuses'' the algorithm so it treats it as a plane. Powered by TCPDF (www.tcpdf.org) Väčšina algoritmov zaoberajúcich sa detekciou črtov, nemá dostatočnú robustnosť voči šumu alebo nezvládajú vhodne spoje na povrchu v tvare písmena T. Prináša to nové výzvy navrhnúť taký algoritmus, ktorý nielen nájde črty na zašumených 3D-dátach získaných pomocou 3D-skenera. Dnešné algoritmy aj keď sú dostatočne robustné voči šumu, v okolí spojov v tvare T stratia dôležité informácie o črtoch, nakoľko trojicu čiar alebo kriviek vyhodnotia ako rovinu.
