|Modelling underwater caves from video [message #56641] Sun, 11 November 2012 20:56 UTC
I'm a cave diver (yes, scuba diving in caves that are full of water) interested in 3D modelling. At the moment mapping underwater caves is done using a bit of string with knots in it, a depth gauge and a compass. We've had some success with creating 3D models of individual underwater chambers using overlapping photographs. The restriction is the number of photos required and the size of the cave (8km/5mi of interconnecting underwater tunnels).
So....is there anyone who can help me out with developing a dual video to 3D map technology? We have invested in a dual Contour camera set up and have taken a bunch of paired video footage from the caves. I've seen people creating models from dual video output on land, but only prototypes and nothing commercially available as yet.
Alternatively, is there a way to create each section of cave from photos, and then stitch the sections together?
For those who are interested, you can check out my underwater cave photography to get an idea of the environment we're trying to model.
Thanks in advance for any and all leads or assistance!
