Fast Generation of 3D City Models 84
FleaPlus writes "New Scientist and UC Berkeley News report on research by Avideh Zakhor and Christian Früh on rapidly and automatically generating photo-realistic 3D models (coral cache) of city environments. This is reminiscent of research mentioned here in March, although the approach is rather different. Applications for areas like urban planning, entertainment, emergency response, and the military are discussed. Zakhor's group is also working on 4D systems, to allow for recording of events over time as moving 3D models."

I've always thought that these 3D maps of cities should be combined with satellite imagery so that you could 'paint' the rooftops onto the buildings and streets. In fact, most satellite images are at a slight angle, allowing you to paint the facades of buildings. The techniques from TFA show how you could paint even more facades in the 3D model/map fairly easily. I think the LIDAR data would greatly simplify the painting algorithm, since the correct 3D shape of every object is known.
I can't wait for the day when we can browse 3D maps online of any city. It would be useful for surveyors and architects of course, but also useful for planning trips, learning geography, and so on.

There are systems like this however. If you look up computer vision research you can typically see stuff about systems that automatically build a "map" of the world. (Typically used with robots.)

I respectfully beg to differ. When you or any child can paint something as nice as Les Desmoiselles d'Avignon [moma.org], I'll admit that Picasso was without talent. Sure, a lot of 'modern' art these days is bunk, but Picasso shouldn't be classified with that junk.
