UWIS underwater GPS navigation continues apace with real-time viewing of 3D wreck models during a dive.
Regular followers of the Vobster Photogrammetry Project will know we have been working on this for some time. The project is all done in our spare time, for free and for the sheer joy of pushing the boundaries of photogrammetry. The game changer has been the introduction of UWIS and underwater GPS. To keep the Read more about A Snapshot in Time[…]
Underwater GPS being used to reconstruct 3D photogrammetry models.
Underwater GPS meets Photogrammetry For a while we have been using GPS located cameras to construct highly accurate models of defensive structures known as pillboxes. Fixing a camera position above the waves is straightforward enough and you can build representative models without additional scale bars or measurements if the GPS signal is accurate. The problems Read more about Accuracy Defined?[…]
Reprocessing old data to yield new results. Lessons learned from police forensic requirements applied to the SS Gwladmena.
Discussion around the use and benefits of accurate GPS values with image alignment in photogrammetry
Long time friend and collaborator Grahame Knott of Deeper Dorset decided he wanted some art to hang in the house. Whatever was going to hang needed to be relevant and big enough to fill the wall in a single image. With everything in life, size matters and the opportunity to print an ortho photo was Read more about Go Large & Print Big[…]
Living in the South East of the UK you are never far away from reminders of more turbulent times. Built during 1940/41 and stretching across the the country are lines of bunkers – known as pillboxes – and other fortifications intended to slow down an invading army. Type 24 Pillbox by Deep3D on Sketchfab. Thankfully Read more about Line of Control[…]
Discussion on the benefits of orthophotos, the limitations of viewing these files online and how a solution to online viewing has been found.
Sketchfab Maps The previous update discussed how Sketchfab labs had started to test the waters with geo locating 3D models. One limitation for those of us who work with underwater photogrammetry was precise location. When generating the tagging code all we could was get close and there was no way to enter precise longitude and latitude coordinates. Read more about Recent News – Maps and Mags[…]
