Video is a nice watch, especially as this is from 2007, so the state of the art should be even better. https://www.youtube.com/watch?v=UZ7_ED9g4FY https://www.

- pen2l 11y agoGoogle Tango (https://www.google.com/atap/project-tango/ https://www.google.com/atap/project-tango/) is able to do pretty impressive 3d reconstruction from what I hear. However it has a number of cameras, whilst linked technique can work with just one image (with enough training).
- leeoniya 11y agoreconstructing depth from 2+ offset images is vastly simpler than from a single frame.
- pen2l 11y agoYup, but I think there's a desire to get good 3d-reconstruction techniques for single images because in practice you often want to do reconstruction in extremely small environments where using multiple cameras is sometimes not feasible for various reasons.
- leeoniya 11y agoGoogle Camera can already do this from a single camera. It takes a bunch of photos as you move the phone around a bit and reconstructs the depth from multiple shots. http://googleresearch.blogspot.com/2014/04/lens-blur-in-new-google-camera-app.html http://googleresearch.blogspot.com/2014/04/lens-blur-in-new-...
