Dan,
Just an update to this; we are now offering spoolpiece metrology using laser-augmented photo-grammetry.
The best way thus far is to drop hardened laser-engraved metal tags onto the seabed and then use a digital stills camera to photograph from one tag to the other (it’s like following a trail of breadcrumbs). When you want to clean up – just stick a magnet in the manip and suck em up.
Anyone familiar with the story of the minotaur and the labyrinth will understand why we are calling this new system THESEUS.
