Come to think of it, using the simple PD controller, what if you based your feedback from a different position, such as the top of the rotors. You could pretty simply calculate this based on the scale, translation, & rotation of the 3 points you're measuring
That is a good idea. I actually did an analysis to find the exact point of rotation and do exactly that. The problem is that the rotation point changes dynamically, depending on what exactly the heli is doing at the time. I got something that worked better in most cases, but if it ever perturbed an oscillation, the point moves up, and the oscillation becomes worse, and the point moves further up...
What kind of interface do you use to emulate command PC to Helicopter?

its quite easy idea but lot has to go in algorithm ... trying using labview vision system it makes things easy

Will you be publishing your control algorithms?

Congratulations! It'd take a lot of courage to put a lovely helicopter under the control of an untested program!
