Recently we helped IANTD run the first two day Diving Skills for Photogrammetry course at Vobster Quay Inland Diving. The course teaches not only how to dive and work as an efficient buddy pair to capture the photos needed, but goes into some detail as to how Metashape uses the images to align and build Read more about Aligning The Images – Why Things Go Wrong[…]
With the release of Metashape 1.5 we get a choice with the route to mesh creation: Depth Maps Dense Cloud For some purposes we don’t really need a mesh, the dense cloud is just a series of defined points in 3D space but can have GIS information and scale applied. But for most uses – Read more about Mesh it up – Depth Maps vs Dense Cloud[…]
Pre-Restoration Scan Recently we acquired a very rare WW2 vintage torpedo motor from Deeper Dorset‘s very own Grahame Knott. The motor is unusual; instead of the typical 4-cylinder radial configuration this example is an experimental 2-stroke 8-cylinder radial engine. As far as we know the engine was never put into production, but there are a Read more about More Than One Orthophoto[…]
Need 3D? The 3D hosting site we use to display our work has been offering models for sale for a while. With the two iBooks (see below) now published and a trip to Scapa complete and processed finally there was time to take a closer look. Sketchfab is not the only site offering 3D models for Read more about Models for Sale![…]
Last Roll of the Dice At 23:32hrs on the28th of October 1918 the Flotta Mining Hut triggered the remotely controlled minefield that guarded Hoxa Sound, thus sealing the fate of the submarine U.B.116 and her crew. U.B.116 had departed Heligoland early on the morning of the 25th with orders to attack the Royal Navy base Read more about 100 Years Ago Today – The Sinking of U.B.116[…]
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[…]
Slope Analysis As we have discussed before Digital Elevation Models help us understand subtle changes in depth (or height) of the subject. We also think they are art in their own right. Tucked away in the 1.4 release of Agisoft Photoscan Pro is a preference that adds slope analysis. The colours applied to the model Read more about DEMS – Another View[…]
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 Most Boring Model on the Internet Its never a good idea to test software capabilities when the pressure is on to deliver a job. The manual may well claim everything works out of the box but its a high risk strategy. Which is how we came to find ourselves standing in a field flying Read more about Rolling Shutters and Boring Models[…]
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[…]
