Object Tracking in a 3D Space
I suppose this belongs in the Sensors forum, otherwise feel free to relocate it.
I have a 3 dimensional space ~200ft(w) x 50ft(l) x 8ft(h). A person (or many at once) walk arbitrarily through the space. I would like to be able to track their "x,y" position in the space. While vision might be a viable option, I was wondering if the members of this forum might be able to offer some additional suggestions.
There are really no constraints other than the person could not carry excessive equipment. A small circuit would be perfectly acceptable.
Thanks in advance.

All the target has to do is carry a 40KHz listening device and some processing power - Prop could do it.
What's the update rate and resolution your wanting?

No can do. We cannot alter the space that much. This was the first thing I thought of too.

I like the ideas so far though.

BTW why do you need to keep track of these people? And what is the room for?
Wow just stole CannibalRobotics idea. Sorry CannibalRobotics!

Can you treat the detected humanity as an amoebic mass, or do individuals matter? In other words, if two people are standing very close together, do you need to recognize them as two people, as opposed to one of more profound carriage?

And what happens when person one leaves the room? Does person two then become the new person one?

I had an image made to show you what I think CannibalRobotics meant but the Forums will not let me upload to night so i will try to talk it out.
First for the transmitter part you have an ultra sonic emitter in each that send out a ping one after the other. Then you have each person with a receiver, the receiver consists of a prop, an Ultra Sonic receiver and an RF transmitter. The RF transmitter is for the props to transmit their position.

I can piece together an x,y of the person by pinging each transmitter with precise timing? Will they reach 200'?
Yes you should be able to find the exact spot where they are and you will always be able to tell were person 1 is. What do you mean by "Will they reach 200?"
