Earlier this week Kevin Heath of Sula Diving kindly towed his side scan sonar fish past the remains of the UB 116, generating a very clear image of the wreck site: Relating the Model to the Planet With the GPS positions recorded in the sonar we can now extract a few key points and add them to Read more about Geo Referencing the UB 116[…]
Scapa Processing Continues What seems like an age ago we were in Scapa Flow diving from the good ship MV Valkyrie. Some of the models were completed on board – like the discovery of a German Pinnace whereas others such as the UB 116 took a little longer. Near the end of the list of wrecks to process is the Read more about Decimating the Model – the V83[…]
A New Target Last week The Shipwreck Project surveyed and confirmed another sonar target. Before diving and upholding a long-held Project ritual, the lump was christened “The Block Of Cheese” on account of what it looked like on the sonar. Here’s a screen grab of what we were looking at: The Scan The target was quickly confirmed Read more about Tidal Streams and Photogrammetry[…]
How much? Photogrammetry produces a lot of data. Here’s a walk-through of the kind of volume needed to create the High Seas Fleet pinnace found last month in Scapa Flow:- Volume of data by event From beginning to end we have:- Dive – 598 RAW files = 15.32Gb Initial processing – 598 derived JPEG images Read more about Photogrammetry – Managing the Data[…]
Deep3D are long-time supporters of Weymouth-based The Shipwreck Project, a group dedicated to finding and researching shipwrecks in the English Channel. Over the years of involvement Deep3D have dived quite a few previously unseen targets, some that have turned out to be junk, and some that have been a historical jackpot. Target diving and site recording Read more about A New Wreck Discovery![…]
Over the last week the NDAC model grew a little bit, with the BaE 146 aircraft joining the overall site (Thanks Marcus!). An updated model will be published soon. GPS Data Other progress included adding GPS data, using Google Earth to glean the latitude and longitude of the various buoys that mark the attractions. Depth was taken Read more about NDAC Orthophoto[…]
Regular visitors to the News section may remember that Simon Brown (Deep3D) and Marcus Blatchford had a very informal project running to map as much of the National Diving & Activity Centre as they could. If you want to read more about how the model was created, do please read on. But if the model is all you Read more about The NDAC Diver Attractions Model[…]
The Model Digital Elevation Models (DEM) are one of the outputs photogrammetry delivers. They are (almost) free, as long as you have GPS data (Latitude, longitude and depth) for known points then orientating and generating a view of the undulations of the scan is straightforward. The SS Gwladmena was scanned back in August 2016. At Read more about Digital Elevation Models Revisited[…]
Spring 2016 saw Deep3D collaborating and contributing to a ground-breaking project – the Coronation Wreck Virtual Dive Trail. The association with the Coronation site and the licensees was long-standing, with both traditional photography and 3D photogrammetry work already completed so when it came to commissioning the work MAST turned to Deep3D. However, the whole site Read more about Deep3D and the Coronation Virtual Trail[…]
Yes, you read the title correctly! Word of what Deep3D was up to in Scapa Flow this November reached the editors at BBC Orkney. Intrigued to know more, they sent along a reporter and recorded a short interview with Simon. The interview begins at 12 minutes 50 into the broadcast:- Photogrammetry on the BBC. The Read more about Underwater Photogrammetry…on the radio[…]
