Control Points Defined

Regular visitors will know we use the UWIS system to track our movements and camera positions as we work on the Vobster Photogrammetry Project. But what if we turned the idea on its head? Instead of tracking the camera or diver as it moves around could we use the UWIS tracker units as a static Read more about Control Points Defined[…]

The Value of Quality

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[…]

Aligning The Images – Why Things Go Wrong

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[…]

Mesh it up – Depth Maps vs Dense Cloud

With the release of Metashape 1.5 we get a choice with the route to mesh creation: Depth Maps Dense Cloud For some purposes we don’t really need a mesh, the dense cloud is just a series of defined points in 3D space but can have GIS information and scale applied. But for most uses – Read more about Mesh it up – Depth Maps vs Dense Cloud[…]

More Than One Orthophoto

Pre-Restoration Scan Recently we acquired a very rare WW2 vintage torpedo motor from Deeper Dorset‘s very own Grahame Knott. The motor is unusual; instead of the typical 4-cylinder radial configuration this example is an experimental 2-stroke 8-cylinder radial engine. As far as we know the engine was never put into production, but there are a Read more about More Than One Orthophoto[…]

Maps and Sketchfab

Where is it? Just the other day the discussion here at Deep3D was all about answering the question Where am I? Now we can share where is it? Sketchfab is the place where most of my work ends up being shared and viewed. You can upload directly from within Agisoft Photoscan and there are some very neat tools to Read more about Maps and Sketchfab[…]

Decimating the Model – the V83

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[…]
