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[…]

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?[…]
