Scanning the World in 3D

Scanning the World in 3D

  In a similar vein to the image-matching against point-clouds that was demonstrated in the Bing Maps TED talk, PhotoCity is aiming to progressively construct a 3D scan of the world. To this end they have released a free iPhone app that displays current scans,…

Converting PhotoSynths to Dense Point-Clouds

Converting PhotoSynths to Dense Point-Clouds

I’ve discussed (with examples of a reconstruction from Newcastle) some of the technologies for doing 3D reconstruction. PhotoSynth is by far the easiest way to get into this, but it is not as powerful as some other options. For example, PMVS2 allows you to reconstruct…

In-game rough mesh of Newcastle reconstruction

In-game rough mesh of Newcastle reconstruction

A few weeks ago I posted the point-cloud reconstruction of an event in Newcastle, Australia, created from photos. My research colleague Jules Cromarty has meshed the point-cloud and brought it into the computer game Crysis. Here are the results:         This is…

Large Scale 3D Fabrication in Sand and Resin

Large Scale 3D Fabrication in Sand and Resin

From Beyond the Beyond and Shapeways blog: Inventor Enrico Dini has built a large-scale 3D fabricator that uses sand and resin to construct some fantastic shapes, presumably at a strength appropriate for buildings. (Try and ignore the contrived-cool fashion of the presenter):

Dense point-cloud reconstruction

Dense point-cloud reconstruction

I have been working with Bundler and PMVS2 to reconstruct some of my old multi-camera scans from 2007. There is a lot of potential to get some really good output from them, but at the moment I’m getting incomplete results; only one side comes out….

How to Build Cities from Tourist Photos

How to Build Cities from Tourist Photos

My research colleague Vinh Nguyen sent me this video of Washington University’s latest image-based reconstruction project (via a New Scientist article “Entire cities recreated from Flickr photos”).     The video shows reconstructed mesh models of the city of Rome. The meshes were constructed using…

3D scanning with a webcam

3D scanning with a webcam

Qi Pan, a 3rd year PhD student at Cambridge University Engineering Department, has developed a system for on-line (constructed in real-time) webcam based reconstruction of textured 3D models. The video shows off the potential for this best: Even better news is that a demo may…
