Why are parts of the tunnel blurred out? Censorship? Surely it isn't anything objectionable we wouldn't see on Wikipedia or Google Image search. Censorship of educational material is unnecessary. Edit: it appears to blur the textures immediately above on the y axis. Perhaps the software isn't correctly interpolating those values even though it has the data. I hope this is the case rather than the censorship I posited…

Probably just a hardware blind spot, this is quite common to find on panoramic views (google street view, etc). Interesting that it sits above, rather than below the capturing apparatus, as it usually does: the tripod gets in the way. Maybe they lifted it from above?

This is amazing. Anyone knows how Matterport works? Does it extract the 3d meshes from 360 photos?

Seems like a combination of 360 photography and off-the-shelf photogrammetry algorithms. Don't know if there is some secret sauce needed (not obvious from the content that there would be).

Well, do you know where these shelves are? I'd be interested in photogrammetry software to reconstruct 3D models of environments, mostly to plan construction or aesthetic changes to buildings or surroundings. This is for home use, so I don't really need fancy texturing, etc. But having it reconstructed from a smartphone video feed would be a must.

I looked for open source software a while back, but didn't really turn out interesting results :/

Edit: there seems to be a few interesting resources. It looks like MicMac could be quite simple to use, and desn't have a CUDA dependency, for instance.

The pictures here are very well lit -- anyone know how they achieved this? There do not seem to be visible lights in the photos.

There is an LED lighting system alongside the walkways, at floor level. It probably isn't original.

Oh my. Thank you for finding these. I would pay a fair bit of money to have a docent of some sort take me around these places in VR. I can't actually visit Egypt anytime soon.

If you've got a PC headset this is pretty good: https://store.steampowered.com/app/861400/Nefertari_Journey_...

Glad you like it!

Matterport's camera uses a mixture of structured light, deep learning, and other techniques to build a 3D point cloud from each capture. Then, the app aligns the different captures together to produce a 3D mesh.

It's also possible to use consumer 360 cameras with Matterport's app, though accuracy is lower. In this case, the 3D-from-2D estimation primarily happens using deep learning.

You can learn more here: https://matterport.com/how-it-works https://matterport.com/cameras

Matterport is a YC company from way back in 2012.

It’s amazing how vivid the blue paint deep into the tomb has remained.

For some reason, I am getting motion sickness while clicking around. But it's really detailed and cool.

Me too. Wonder if a VR version would be less nauseating.

Doubly impressive: there are spots you can visit in the vtour, that you cannot see in real life because they're outside the pedestrian walkway. Example: https://photos.app.goo.gl/NXdDoDTnNXJgkr8X9

I'm sure the guards there would encourage you have the privilege of a view from off the pedestrian walkway for a tip.

While Egypt is generally loose in this regard, they are super strict about few things. Sharm Elsheikh's reef come to my mind.

its awesome, although at first i thought i was going to see it as it used to be. that would be a neat project
