Discussion examining the benefits of occlusion maps applied to Metashape models to improve level of visible detail with low poly count plus review of online hosting of massive detail models.
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[…]
Short article discussing the use of Dense Cloud Confidence to filter points and reconstruct 3D models
Reprocessing old data to yield new results. Lessons learned from police forensic requirements applied to the SS Gwladmena.
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[…]
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[…]
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[…]
Freeze Frame Until now converting video into still photographs required a piece of third party software. Since the release of Agisoft Photoscan 1.4 the ability to import video directly has been added. It was time to investigate and see what this function offered us. With enough light to warm the ocean and a housed digital SLR camera Read more about Photoscan 1.4 – Importing Video[…]
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[…]
