A while back I nearly didn’t answer the phone. It was one of those international numbers and I didn’t recognise it but something told me to pick it up. I spent the next 30 minutes chatting to John Kinsella of Ocean Divers in Ireland all about 3D reconstruction and how it could be used in Read more about Wrecked in Second Life[…]
Short discussion on first dive after COVID-19 lockdown and using UWIS tracker for 3D reconstruction and improving local accuracy of model with adjustments to tracker unit location.
UWIS underwater GPS navigation continues apace with real-time viewing of 3D wreck models during a dive.
Discussion on UWIS navigation and Metashape photogrammetry using depth maps
The seabed and wrecks are dynamic environments. As divers we are not always aware of just how much things change unless something dramatic occurs. In 2012 the stern of the Karlsruhe was very ship-shape with neat lengths of teak decking in place. Then the stern winch capstan collapsed to the seabed and upended everything.

Everything was set; the Heart of Gold was prepared, the Suex scooter ready and the mindset was prepared for some serious scanning. The base for the week was Read more about Invasion of the Wreck Snatchers[…]
3D Work in Scapa At least once a year we take the long drive north to Orkney and Scapa Flow for a week of diving onboard the MV Valkryie. The Flow has been used as a military base during both world wars and the German High Seas Fleet was interred and scuttled there in 1919. Read more about Scapa Flow – The Results[…]
Atlantis at Alikanas Late last year Simon found himself on the island of Zakinthos, Greece, in the company of a film crew. The job was to scan the seabed of Alikanas Bay and capture what locals believe to be the remains of a long-lost town. The job went very well indeed. The weather and visibility Read more about Media Work – Looking for Atlantis[…]
The Thunderbolt A few weeks ago Deeper Dorset divers paid a visit to the P47-D crash site in Weymouth Bay. We know a fair bit about this crash site but a dive after the winter storms usually reveals something new. Conditions were not great and visibility limited but Hugh did come back with a photo of a Read more about Ortho Photo – The Gift That Keeps Giving[…]
Tips and Tricks Keeping with the theme of recent posts about light, we have some tools available in Photoscan available to us. Like any tool, its useful to know when to apply them and when the outcome might not be quite as we hoped for. Here’s a screen grab of a model as processed with Read more about Photoscan and Light[…]
