3D cave scanning in Devon

That's the best interface I've seen for navigating a 3D scan like that. I'm sure at some point 3D scanning and LIDAR on phones etc will replace digital surveying tools, but at the moment I've not seen a good workflow for converting these 3D scans to a paper survey for in-cave navigation. Even the survey used for that 3D scan is an old one produced using traditional methods.

That is so cool. It would be great to have that done for loads of caves.
How long does something like that take to compile?

The photographs are taken at each location with the circle on the floor, so that is a lot of stops, so pretty time consuming.
The 3d mesh is quite crude, from what I can tell it is only 1.2MB of data, but it works very nicely, the images make up for the lack of 3d detail.

The origins of the software in producing models of houses for estate agents etc shows, with the interface allowing you to select which "floor" to look at. Street view for the home!

Indeed, a very good interface.

Not sure "3D Scan" is the right term for this, photogrammetry probably better.

Would like to see a "proper" cave using this interface.

Worth mentioning that Andy's link doesn't seem to work too well, I got the page but then I just had the whirling circle of endless delay.

Same here. Looking at the network comms via Firefox's Tools -> Browser -> Web Developer I see a lot of POST requests failing:

It used to work OK; I just assumed it was the dodgy wifi in the hotel where I'm staying.. Perhaps there is a role for BCA or the Cave Surveying Group to act as an archive this type of survey data as it is all too easily lost...

It has been discussed before but would require significant increase in data storage capacity, I did offer to write a funding proposal for the registry but I suspect a standard format/resolution/file size would be needed first.

I'm not sure scanning will replace 'traditional methods' - parallels can be made with OS maps for instance which are not just lidar... This is a hot topic at survey meetings though and if that sounds like something you'd be interested in then you should join the CSG 😁
