Tracking

I noticed that whenever the camera was tracking it was tilting downwards and then stopped tracking the green. Is this because I don't have a setting right for the noise filter or a value wrong for the RGB values. Any help would be great.

Re: Tracking

If you are using Kevin's code, the way the camera is mounted matters. If you mount it with the on-off switch near the top, you have to go and change a few signs in your code or else it will always try to move away from the light instead of centering on it.

Re: Tracking

Here's what JSonntag is refering to in the code.
From tracking.h

Code:

// If your camera suddenly moves away from the target once

// it finds it, you'll need to change the sign on one or

// both of these values. Start with the tilt first.

#define PAN_ROTATION_SIGN_DEFAULT -1

#define TILT_ROTATION_SIGN_DEFAULT 1
