Die Entwicklung der Computergraphik und ihr Einsatz bei der digitalen Architekturrekonstruktion
(2018)
Die digitale 3D-Rekonstruktion von Architektur- und Archäologieobjekten ist eng mit der anwendung der Methoden und Systeme der Computer Graphik verknüpft. Dieser Artikel stellt solche Verbindungen seit den Anfängen der Computergraphik in den 1950er Jahren bis etwa zur Jahrtausendwende dar. Die Entwicklungen von Methoden zur Gewinnung von 3D-Daten, i.e. 3D-Scannverfahren und Photogrammetrie, werden ergänzend kurz betrachtet.
Motion capturing plays an important role in computer animation and combines many different fields of research in media engineering, such as camera calibration, marker detection via image processing and 3D reconstruction. Most professional motion capture systems are distributed proprietarily by a handful of companies and do not grant much insight into detailed workflows. The motivation for the project this thesis is based on was to autonomously develop a simpler, yet similar system, which would capture static poses of a puppet. This thesis points out the designing steps of this system and illustrates how many of the aforementioned aspects of motion capturing are answered using the example of the stop-motion capture system, thus building a basis for the comprehension of more complex systems.
