In the Beginning… In our temperate northern waters there is a lack of light. The very thing that underwater photogrammetry needs is often in short supply and light is like a drug. You always want more. Underwater photographers get around the limits of natural light with flash guns or video lights and these generally work Read more about Let There Be Light[…]
Where am I? Trying to scan underwater sites such as submerged landscapes or very broken wrecks often results in becoming hopelessly lost. Add into the mix the vision limiting experience of low visibility and a difficult job gets a lot harder. When on a sightseeing dive disorientation can be frustrating as you fin around missing Read more about Underwater GPS and Photogrammetry[…]

The Project The SS Thistlegorm is rated a world class wreck dive. But only a tiny fraction of the world can don SCUBA and pay the wreck a visit, so the Universities of Nottingham, Ain Shams and Alexandria have collaborated to digitally record the heritage beneath the waves. Funding for this work has been provided by Read more about Project Thistlegorm – The Processing Begins[…]
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[…]
Deep3D were back in the wreck diving spiritual homeland of Scapa Flow last week, sleeping, eating and diving from the MV Valkyrie for 6 days of cold water fun. The majority of the wrecks of Scapa Flow date from the First World War and are very big subjects indeed. Previous experience teaches us that scanning large subjects can be exhausting Read more about The Heart of Gold & UB 116[…]
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[…]
