diplomsko delo

Abstract

Diplomsko delo obsega študijo algoritmov, ki odstranjujejo osirotele točke, ter njihovo primerjavo. V nadaljevanju bomo predstavili osnove pojme, ki so potrebni za razumevanje našega diplomskega dela. Po predstavitvi pojmov bomo podrobno spoznali teoretično ozadje, delovanje, vključene algoritme in implementacijo metode kvartilnega razmika, statističnega filtra, filtriranja s polmerom, pogojnega filtra, ter filtriranja z mnogotero razdaljo in aproksimacijo normale. Implementirane metode testiramo nad različnimi oblaki 3D točk, z različnimi parametri in prikažemo rezultate. Analiza rezultatov kaže, da je na splošno najbolj uporaben statistični filter.

Secondary title: Algorithms for outliers removal from 3D point clouds
Secondary abstract: In our thesis we conduct a study and comparison of algorithms for outliers removal. Firstly we present the basic concepts needed for understanding the thesis. After presenting the concepts, we explain the theoretical background, operations, involved algorithms and implementation of the interquartile range method, statistical filter, radius filtering, conditional filter, and filtering with manifold distance and normal estimation. We test the implemented methods on multiple 3D point clouds with different parameter settings and display the filtered results. The resulting analysis shows, that the best filtering method is statistical filter.
