The home of forensic photogrammetry
Last month’s visit to Shetland was very productive. A week a way in cold but clear water has yielded some very pleasing models:- https://sketchfab.com/simonbrown/collections/shetland And from these wrecks, it is now possible to create some very large but highly detailed 2D panoramic views of a wreck, big enough to see from bow to stern and Read more about Panoramic Wreck Prints[…]
A combination of depth (38m) and size (67m x 9m) prevented the SS Gwladmena being scanned on a single dive, but by taking two sets of images from different dives the entire ship can be built. Dive one concentrated on the plan view of the decks. Dive two concentrated on the surrounding seabed and hull. Read more about Updated, refined & revised – SS Gwladmena[…]
Now lying in 30m of water, this small trawler sunk just over 17 years ago and now lies on a seabed of near-white sand. Thankfully no lives were lost during the sinking, and today the wreck makes a great 3D subject.
With the summer here, Deep3D has been busy. One very large and collaborative project will be published later this year but we have managed to slip away and scan some wrecks in Shetland. Built in 1878, the SS Gwladmena sank in 1918 and now lies in 38m of water close to Lerwick. At 70m long Read more about SS Gwladmena – Shetland Islands[…]
One reason Marcus scanned the trawler was thanks to its close proximity to the Wessex helicopter, something Deep3D scanned a while back. By including part of the helicopter in his scan, Marcus captured enough for us to merge the models and start to build on the map of the shallow end of the National Diving and Read more about More Merging[…]
Deep3D friend and fellow photographer Marcus Blatchford paid another visit to the National Diving and Activity Centre and scanned the trawler “Caroline” that was sunk earlier in the year. A few hours transferring and building the model and here’s the result:- But Marcus scanned beyond the trawler…check back soon for another update on the plan to scan Read more about More NDAC models[…]
Last year The Shipwreck Project found another cannon site. Four cannon and anchor, all slightly unusual in their shape and judging by the concretion very old indeed. We paid the site another visit on the 16th of May and scanned one of the larger guns:-
At Deep3D we realise we cannot be everywhere, all the time. But should that mean we can’t create a 3D model from another photographer’s scanning, build a model and then merge it with existing data? Can we do just that? The short answer is “Yes we can”. Fellow diver and photographer Marcus Blatchford offered to Read more about Merging data from different dives, and different divers.[…]
Here at Deep3D we like to do things a) once and b) right. Accurate models are far more useful than pretty images, but accurate and slightly “arty” really is what we strive for. After building the latest model that merged two sets of scaled data, we wondered just how accurate the resulting model was? Two divers, Read more about Close to reality, but how accurate?[…]
Being underwater automatically limits how much area you can cover. At some point, you need to return to the surface and recharge your cylinders, eat, use the toilet and such. It can mean a big compromise between area covered and detail. But what if you could scan a subject, process the data and then return Read more about Merging data from different dives[…]
