Unrelated but why isn't anyone seemingly doing cave photogrammetry? Why can't I virtually tour faithful 3D-maps of real caves?

- Stevvo 4y agoCaves are generally lacking in light, a prerequisite for photogrammetry. Of course one could use artificial light, but that comes with its own challenges.
- hoseja 4y agoYou mean flash(light)? Also what about LiDAR etc.
- Stevvo 4y agoI'm reminded of a fun little game from Introversion Software; A Scanner Darkly. You explore a dark cave with only handheld LIDAR scanner. A fun little curiosity, but nobody bought the game. I imagine actually scanning caves with LIDAR would be much the same; a fun curiosity, but not commercially viable.
- hoseja 4y agoThere are commercialized, well lit, walkable caves thousands of people visit and yet there are no good models of any of them.
- poulpy123 4y agobecause it's expensive and the conditions very difficult. People are starting to use lidar techniques to map caves however.
