3D scanning the “Walhalla” in Donaustauf with structured light, photogrammetry and LiDAR
In 2020 I worked at TVN Corporate Media in Hanover to digitally capture the facade and interior of Walhalla for a publication in the web mapping platform “BayernAtlas”.

TVN Corporate Media is a media agency for corporate communications specialized in motion picture. Its team executes social-media campaigns, employer branding, advertising films and everything in between. It also creates immersive 360° content for VR and AR applications, Fulldome films or in this case: a virtual tour through history.

With a team of five, we used photogrammetry and LiDAR scanners to record the geometry of the greater areas as well as handheld structured-light scanners for the exhibition models. As part of the TVN team, I specialized in the technical direction of the different scanning methods.
Heavy data optimization was needed to ensure an all-accessible online experience. During post-production, we established a workflow to reduce the download size and the necessary computing power while remaining the best possible visual appearance for the browser application. We accomplished that by reducing the geometrical information on the 3D models in combination with Normal Maps. This way, we were able to regain the visual quality more efficiently.
