Let There Be Light Part II

Orcalight A few weeks ago we shared the news that the Orcalight Seawolf had been upgraded. The original single battery canister and light head was returned to Shane at Orcalight for modifications. A second light head and improved batteries were in the upgrade and the intention was to improve the coverage of light when working with a Read more about Let There Be Light Part II[…]

Let There Be Light

In the Beginning… In our temperate northern waters there is a lack of light. The very thing that underwater photogrammetry needs is often in short supply and light is like a drug. You always want more. Underwater photographers get around the limits of natural light with flash guns or video lights and these generally work Read more about Let There Be Light[…]

The Heart of Gold & UB 116

Deep3D were back in the wreck diving spiritual homeland of Scapa Flow last week, sleeping, eating and diving from the MV Valkyrie for 6 days of cold water fun. The majority of the wrecks of Scapa Flow date from the First World War and are very big subjects indeed.  Previous experience teaches us that scanning large subjects can be exhausting Read more about The Heart of Gold & UB 116[…]

Updated, refined & revised – SS Gwladmena

A combination of depth (38m) and size (67m x 9m) prevented the SS Gwladmena being scanned on a single dive, but by taking two sets of images from different dives the entire ship can be built. Dive one concentrated on the plan view of the decks. Dive two concentrated on the surrounding seabed and hull. Read more about Updated, refined & revised – SS Gwladmena[…]

SS Gwladmena – Shetland Islands

With the summer here, Deep3D has been busy. One very large and collaborative project will be published later this year but we have managed to slip away and scan some wrecks in Shetland. Built in 1878, the SS Gwladmena sank in 1918 and now lies in 38m of water close to Lerwick. At 70m long Read more about SS Gwladmena – Shetland Islands[…]

Close to reality, but how accurate?

Here at Deep3D we like to do things a) once and b) right. Accurate models are far more useful than pretty images, but accurate and slightly “arty” really is what we strive for. After building the latest model that merged two sets of scaled data, we wondered just how accurate the resulting model was? Two divers, Read more about Close to reality, but how accurate?[…]

Merging data from different dives

Being underwater automatically limits how much area you can cover. At some point, you need to return to the surface and recharge your cylinders, eat, use the toilet and such. It can mean a big compromise between area covered and detail. But what if you could scan a subject, process the data and then return Read more about Merging data from different dives[…]

More Orcalight Seawolf results

With the Alvis Saracen model demonstrating what the Orcalight Seawolf can do for lighting a subject, we processed more images from last week. Sitting in 30m of water, the NDAC Westland Wessex (tail ID XS122) was a challenging subject. With thin walled sections of the airframe, it was going to be interesting to see how Read more about More Orcalight Seawolf results[…]

More testing…more results

Deep3D paid the National Diving and Activity Centre a visit recently, with the objectives of testing a few more methods and means to scan subjects underwater. One test was to use the Orcalight Seawolf dive torch to illuminate the subject in question, rather than use the more traditional underwater strobes (flashguns) to apply the light.
