Go-3D Conference 2019 “With 3D towards MariTIME 4.0 “, September 5, 2019, in Rostock

During the Go-3D 2019, organized by the Fraunhofer Institute for Computer Graphics Research IGD in Rostock, Germany, I had the opportunity to present my latest research paper about “Close range underwater photogrammetry for a high-resolution survey of a coral reef: A comparison between reconstructed 3-D point cloud models from still image and video data“. The article went through a peer-review and discusses the potential of underwater photogrammetry and underwater videogrammetry for close-range submarine survey processes of complex 3D objects such as corals.

Reconstructed 3-D point cloud model of a natural coral reef from high- resolution still images. The point cloud model has 621,912,135 points (Vogler V., 2019). 

Coming from a different background, I enjoyed new input regarding ship construction, hydrodynamic modeling and especially the examples for useful VR, AR and AI applications in the marine and submarine environment.

2ND Publication ABOUT ARTIFICIAL CORAL REEFS

The second publication, “High-resolution underwater 3-D monitoring methods to reconstruct artificial coral reefs in the Bali Sea: A case study of an artificial reef prototype in Gili Trawangan“, is a peer-reviewed journal article presented and published at the DLA Conference 2019 in Dessau. It discusses the design and high-resolution underwater monitoring methods to measure and understand in detail growth processes and complex surface configurations of our artificial coral reef prototype 1. In this article, we present the specific workflow to survey marine environments using underwater LiDAR scanning (M210UW Newton Labs underwater laser scanner) and high-resolution underwater photogrammetry (Sony Cyber-shot RX100 II and Canon EOS 5Ds) and voxel models from high-resolution computed tomography (CT) scan of an extracted sample of Prototype 1.

Thanks to both co-authors Jun. Prof. Jan Willmann and Prof. Sven Schneider and the amazing group of collaborators of until this point!

1st Publication ABOUT ARTIFICIAL CORAL REEFS IS out

I am excited about my first publication about the design and construction of artificial coral reefs in the Bali Sea together with the Andrea von Braun Foundation. More than 53 pages illustrate reef design using digital design tools, fabrication and installation in at Lombok island and show the monitoring process during the past 6 years and underwater 3-D scans using underwater laser scanning and underwater photogrammetry.

The foreword is in German, the rest in English. I am thankful for this opportunity and for the chance to collaborate with such a remarkable group of people. THANK YOU Bert, Jane, Philipp, Georg, Robin, Isabella Weinberger, Christoph-Friedrich von Braun, Delphine, Thomas and Uli!

Underwater Monitoring of Reef Prototype 1

Seascape Prototype #1-33

On November 15th, 2012 we launched Seascape Prototype #1 at Gili T. in Indonesia.

In the meanwhile, the calcium-carbonate layer that surrounds the metal pieces has grown thicker. The synthesis between mineral accretion fabrication and the digitally developed skeleton becomes more evident as time passes.

Underwater launch pilot reef – Prototype 1

My latest project in collaboration with the Global Coral Reef Alliance and Eco Gili Trust is part of a hopefully continuing research about Artificial Reefs and Computer-based Ecological Manufacturing in Architecture.

Some of the main challenges our civilization is facing are related to environmental depletion and the restoration of damaged habitats. Especially coral reefs currently experience a major crisis. “Seascape Prototype #1” is an experiment: A digitally designed and fabricated metal structure mimics the geometry of natural coral reefs with the increased ability to dissipate the energy of large ocean swells. Through mineral accretion fabrication natural rock formations grow around the synthetic structures with the ability to repair and sustain themselves. As such, they form a natural growing support layer around the proposed synthetic structure. Both, natural rocks and the proposed digital metal structure form an artificial coral reef, contributing to restoring depleted habitats within an integrated computer and nature-based design approach.
