The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

2D-Point-Cloud Reconstruction from Laser-Scanner-Data using Genetic AlgorithmsEder, Rasmus 10 June 2024 (has links)
Die Arbeit widmet sich der Rekonstruktion von Polygonzügen aus 2D-Punktwolkendaten. Die Daten wurden mittels Laser-Scannern erhoben und bilden Grundrisse von historischer Architektur ab. Die Arbeit beleuchtet die Arbeitsfähigkeit von GPU-parallelisierten genetischen Algorithmen, bei dem Versuch aus diesen Daten Polygone und Streckenzüge zu erheben die zu den ursprünglichen Daten kongruent sind.:1 Introduction 5
