PhotoScan + endoscope?

[ThomasVD]

Hey everyone!

Just wondering if anyone here has ever experimented with reconstructing the insides of for instance small objects using an endoscope? It sounds like a tantalizing prospect to be able to access the insides of hard-to-reach small spots and build 3D models but I'm wondering what the user experiences are? Are these sorts of cameras super-expensive? Do they not calibrate well in PhotoScan? Are the resulting images of sufficiently high resolution?

Think this is an interesting topic to explore further

Yes it is an interesting idea...  Most of them have very wide angle lenses so in theory it should be feasible to reconstruct narrow spaces even with a single camera path. Most of the ones I've seen have had limited resolution which could be a problem but I'm not current with what technology is up to now.

Thanks for the reply BigBen. Yeah the endoscopes I've seen so far don't have sufficient resolution, but I imagine that nowadays pretty high-res endoscopes should be available (given what my tiny phone camera is capable of). I'll keep the forums posted in case the idea develops further

Pretty rough quality but extracted to TIFFs and masked annotations..  Assumed a fisheye lens

Nice! Results look very promising The image quality is a lot better than the endoscopes I've seen but I guess it's reflected in the price-tag: the boroscope apparently costs $ 30 000 (see YouTube comments).
