NDAC Orthophoto

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[…]

The NDAC Diver Attractions Model

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[…]

Digital Elevation Models Revisited

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[…]

Deep3D and the Coronation Virtual Trail

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[…]

Mixing Datasets – Photogrammetry and Multibeam

The one nagging thought while scanning is “Did I get enough overlap?”. No overlap of points and the scan data just won’t build into a single, seamless model. For anyone scanning topside data the opportunity to reshoot the missing images can be straightforward, but with shipwrecks its not so easy. The distances involved, boat availability Read more about Mixing Datasets – Photogrammetry and Multibeam[…]

Underwater Photogrammetry…on the radio

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[…]

Digital Elevation Models

Next year sees the start of a little project run by The Shipwreck Project to find the missing pieces in a great story involving a Second World War single seat fighter that crashed in Weymouth Bay. We know the date and the fate of the pilot – he bailed out and was rescued – but we do Read more about Digital Elevation Models[…]

Bunkers & iPhones

Last week Deep3D attended a photogrammetry and digital workshop hosted by Nottingham University and presented some of the underwater work to date. It was a great opportunity for everyone working in the field of maritime archeology to get together and share their work and the results. All the presentations were really interesting and inspiring. The CITiZAN foreshore project Read more about Bunkers & iPhones[…]

Scanning Humans and Other Details

The orthophotos generated from the 3D model can be very detailed indeed, but they can reveal flaws if things move during scanning. With humans, this causes a bit of a problem. Here’s an example of the E49 and model Rob:-   This print is A1 in size and Rob appears alongside the submarine, adding great Read more about Scanning Humans and Other Details[…]

Panoramic Wreck Prints

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[…]
