Hello everyone -
This is probably more of a general practices question than something
specific to Therion. Among the group there is likely to be some
experience with this. I hope at minimum someone can guide me to a place
for further learning.
A few years ago Apple released a very high-end smartphone which has a
LIDAR feature (iPhone 12 Pro). There are a few more models now which
have it. I have heard of some people using this to create cave maps.
There is much I do not understand.
Has anyone in the group taken the point cloud from an Apple LIDAR scan
and turned it into a Therion cave map? If so, I am very interested in
the details of the process.
The biggest issue I see is this: How does the iPhone know where it is?
There is no GPS in a cave. GPS is not accurate enough even if it did
work. Inertial navigation also has big problems dealing with a cave
environment.
There are many other issues, but I think that is the big one.
Thanks!
