UWIS underwater GPS navigation continues apace with real-time viewing of 3D wreck models during a dive.
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?[…]
Details of the Vobster Quay underwater navigation day – showcasing how we use the latest technology to answer “where am I?”
Discussion around the use and benefits of accurate GPS values with image alignment in photogrammetry
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.

Built on a slope, right outside the back door was the planned space for a set of steps that lead into the rest of the garden. Could we design and make Read more about Commit To Cut – Photogrammetry Guides the Saw[…]
Quality In During a brief visit to London’s Victoria and Albert Museum one of the subjects was shot with the best camera to hand – an iPhone. The museum contains a wealth of art – the very finest expressions of what it means to be a creator. There were many worthy subjects but most were Read more about The Value of Quality[…]
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[…]
