Analiza in primerjava 3D zajema s strukturirano svetlobo in fotogrametrijo

Ahčin, Nuša (author), Muck, Deja (mentor)

V diplomskem delu so predstavljeni različni načini 3D zajema objektov. Opisane so različne tehnologije, ki se uporabljajo, s poudarkom na fotogrametriji in 3D skeniranju s strukturirano svetlobo. Glavni namen diplomskega dela je bil predstaviti tehnologije 3D zajema, njihove prednosti in slabosti, hkrati pa tudi preizkusiti dva načina 3D zajema (fotogrametrijski in s strukturirano svetlobo) ter primerjati in analizirati rezultate zajemov. Ugotoviti, kako se načina razlikujeta v sami kakovosti na končnem predmetu, kateri postopek je hitrejši, cenovno dostopnejši, uporabnejši pod različnimi pogoji. Želeli smo odgovoriti na vprašanje ali lahko s cenovno bolj dostopno tehnologijo zajema, to je s fotogrametrijo dobimo primerljive rezultate 3D skeniranju s strukturirano svetlobo. Najprej so bili izbrani predmeti za skeniranje različne velikosti, teksture, barve in oblike. Sledili so različni preizkusi 3D zajema in na koncu primerjava najbolje uspelih končnih 3D modelov.

Abstract

The diploma thesis discusses different technologies of 3D scanning. The thesis describes some technologies with emphasis on photogrammetry and 3D structured light scanning. The goal of the diploma thesis was to describe 3D scanning technologies, their advantages and limitation or disadvantages. The main goal was to test photogrammetry and 3D scanning with structured light and compare the results, to analyse the results of 3D scanning and to establish how these two technologies differ in the final 3D model, to analyse which technology is faster, more accessible, and useful under different conditions. The final goal was to determine, whether there is a way to 3D scan without special equipment with a camera and free open-source software and, for the end result, to still be comparable to the end result with 3D scanning with structured light. The first step was choosing different objects for scanning. The objects differ in size, texture, colour and shape. The following step was testing both 3D scanning technologies and comparing the best results, of each object, of 3D models.
