Metashape Professional and Coral Reef Measurement
« on: June 05, 2021, 11:36:28 AM »
AccuPixel are collaborating with the Submerged Resources Center of the US National Parks Service with the intention of pushing the boundaries of underwater photogrammetry, working with multiple cameras and UWIS underwater GPS positioning data.

Hi Simon,

Amazing work!  I am sure using UWIS GPS is improving processing performance for large projects but are you also finding significant accuracy improvements?

cheers,

Javier

UWIS does three things:

Navigate - it helps us find the target quickly (https://deep3d.co.uk/2021/04/23/back-in-the-water/) using a sonar overlay on the tablet.

Scale - merge the UWIS GPS data with cameras for reconstruction constraints (https://deep3d.co.uk/2020/02/04/accuracy-defined/)

Geo locate - whereabouts in the world is the subject and how does it relate to others?

We have a little app that takes camera and UWIS data and merges them - https://deep3d.co.uk/2020/06/03/you-need-an-app-for-that/ - and version 2 is under development right now, adding a few features to refine accuracy.

And whilst much of this has been available in the terrestrial arena, underwater positioning has been the preserve of military or oil field sized budget holders - until now.

So for us, UWIS adds significant capacity and capability.

Hi Simon

What's the cost of a  UWIS GPS system?
Best Regards
