Fine Tuning Camera Stabalisation

Hi All

 

I have setup my camera mount with servos for cam stabalisation.  My problem is ....

 

As I hold my quad and move it through the pitch and roll axes , the camera moves in the correct direction to compensate for the quad movement BUT in over compensates and moves too far.  Also the camera is off centre in the roll axis. (I use the transmitter to adjust the pitch axis).  SO all I need is a method of reducing the movement of the servos and to centre the cam in the roll position.

This problem isn't new to me as I have been trying to crack it for some time.

 

Some users have written code to resolve this as the Ardupirates code does not seem to work in this area.  One user told us to put code in the GCS section but didn't fully explain where to put the line of code which makes the adjustment.

 

I know that the new code may be out any day BUT it would be nice to get this sorted.  Can anyone help .....

 

I have come up with a really neat way of mounting my GO-PRO underneath the quad without using any undercarriage.  The camera assembly drops into place once I am in the air.  This allows the quad to sit flat to the ground.  A big weight saving and much less drag on a windy day.

 

I will be happy to share a video with everyone once I have sorted out the stabalisation issue ....

I'm looking at the ArduCopter 3DR quad setup and am interested in your GoPro setup, that will be my main, if not only video solution. I'm not going to purchase until I can be assured that mounting and minimizing the jello vibration effect can be achieved. Any input would be very helpful.

Thanks

Ditto!  Philip, please detail what gimbal you got and how well it attaches to the 3DR, since I'm trying to mount a GoPro onto a 3DR too...  Thanks!

the arducopter gopro 2 axis mount works fine. you you need to dremmel some slots into the base plate though.

as for the overcompensating, change the horn poisition or the ratio in theMP params to change tge rate. take a bit of fiddling but works well.
