Impressive! I envy you your Optrack system. Where is this shot?

This clip is shot in Ben Gurion University in Israel, In one of the Mechanical Engeneering labs.
I've been playing around with quadrotors for a while, and when I discovered the optitrack system, I had to see if It will work... :)

That's exactly what I am trying to do, but without the optitrack system. My indoor drone only uses 4 sonars + 1 IMU.

Obviously, I will not reach the same performance.

wow, impressive stability, what is the Optitrack system you talk about, do you have a link?

Impressive stability !
Post details on hardware and post the code ??

I like the tracking system. But so pricy...
Is there anything open source regarding indoor tracking?
I would first think of the sensors (camera) used in the Wiimote. If you could use custom sensors like these, a system should be quite cheap.
Thanks for any hint!

Remarkable stability.
can you to give the material that you took and the code.
Some photographs of readier of the model
Thank you

MarcS I think you can use Wiimote with your pc but you need 2 wiimotes.You need to attach 3-4 leds to your aircraft and track them.You will have to calibrate your system.That means you have to know the position of the leds on your geometrical model and the position in the camera space.This way you match the aircraft space with camera tracking space.Wiimote has limitation because is one camera and you cannot determine 3d position only 2d without depth.You can buy a cheap tracking system like:http://www.clarontech.com/

Hi Inout,
the clarontech looks as if it is designed for small tracking volume (medical). Interesting, anyway.
I´m well aware of the geometry and the necessary calculations regarding point tracking in 3D. You would probably use more then 2 cameras if you have a huge volume. On the other hand you can achieve impressive results with only one webcam and matlab: shreddiquette tracking.
I did some searching the net but it does not seem to be an open source equivalent to systems like optitrack. If I had time, I would start one :-) (too bad I will start my new job soon) Hardware and software skills are available.
Anybody else interested? Could be an interesting DIY project.
