Fast moving rigid body tracking using the TT api
Posted: Sat Sep 26, 2009 3:16 am
Hello,
My colleges and I use a c++ program we wrote to control an autonomous vehicle using position and orientation feedback from the tracking tools api (we have a 12 camera indoor setup).
1. In our program we have a main loop which we desire to run in a constant duration of 10 milli-sec so we can receive each frame. All our calculation and other code in the loop is timed to be 1-3 milli-sec. We were surprised to time the Update_frame() method to be 10-11 msec. In the past we timed it to be 3 msec. How is this possible? Is this because we added more tracked bodies (currently 3 rigid bodies, 13 markers altogether)? Maybe this has to do with wrong settings of the body in tracking tools?
2. We are controlling a Radio Controlled Helicopter which tends to vibrate while flying. The heli moves very fast. What settings do you suggest we use when defining the body in tracking tools?
Thanks,
Ory Schnitzer
