I've implemented a couple of interesting wide area tracking systems in the past and have reasonable expertise on the various technologies involved.
RF solutions will not work indoors to the accuracies that you require (1ft). Too many problems with multi-path.
Vision-based solutions can be implemented, but robust commercial versions are expensive.
If you can dot the ceiling with paper targets and survey them, then use the new IS1200 from intersense (or contract them for a custom 2D version of their vision system without the IMU) (15k per tracker now, price should come down). www.intersense.com
Laser-based systems would also usable. Try ArcSceond's constellation 3DI product. www.constellation3di.com (~60 - 100k)
The Z machine is a pulsed power accelerator consisting of capacitors that, like large batteries, are charged with electricity for more than a minute. The electricity is released in 100 billionths of a second, resulting in a 50-trillion-watt, 18-million-amp pulse. This pulse converges on an array of wires, called the load, creating a plasma. This plasma collapses down onto the axis in what is known as a "Z-pinch" and radiates X-rays.
The photo of a firing of Sandia's Z accelerator shows, in the brilliant arcing of electricity, only the trace amounts of energy that escape. The reaction actually releases, in X-rays, roughly 80 times the entire world's output of electricity for a few trillionths of a second.
It is within this plasma that the reactions take place. The electrical discharge on top is not where the real action takes place.
Yep! People have thought of this one too. Take a look at Cyra's laser scanner . Only one teensy little problem. It costs $150,000. Systems like this work with a time-of-flight laser system and a gimbled mirror to move the spot. The mechanical system is very tight, which drives the cost high. Moral of the story; Good 3D (like 1mm resolution @ 50m) ain't cheap.
This depends on the goal of the compression. Do you want the compression to preserve quality or what I would call "temporal relavance".
For teleoperation of remote systems, it might make way more sense to weight the compression with respect to relative distance, something that is closer gets higher quality where something farther away gets lower quality.

Yep! Great idea. Million dollar one too, which means that it is hard.
The camera produces a 3D point cloud, from which geometry (CAD) does not fall out of naturally.
