Camera tracking/following

EZ-GUI can control your gimbal to get videos like this:

 

Gimbal can be also used as antenna tracker.

To use this functionality you need:

  • Storm32 based 3 axis gimbal – http://www.olliw.eu/storm32bgc-v1-wiki/Main_Page
  • Bluetooth module – http://www.olliw.eu/storm32bgc-wiki/Bluetooth_Module_HC06
  • EZ-GUI with working preferably long range telemetry (I use 3DrRadio)
  • iNav/Multiwii based flight controller
  • full version of EZ-GUI

 

This is my setup:

Gimbal + batteries in the box

gimbal

The procedure:

  1. Pair Bluetooth gimbal with your Android device
  2. Connect battery to your model and wait for good GPS reception
  3. Connect EZ-GUI to model
  4. Make sure that you have good GPS reception 5 satellites or more.
  5. In EZ-GUI go to mission planner.
  6. From menu (three dots in right up corner of the screen) select “Camera tracking setup”
  7. Select Bluetooth module
  8. Bring your model with working GPS and telemetry connection as close as possible to the place where camera will be located and press NEXT button
  9. Move model away from the camera. Preferably in the direction where you will be flying. 10 meters should be enough.
  10. Manually rotate whole gimbal and point the camera at the model and press NEXT button
  11. Done. Press OK. At this point gimbal should follow the model.

Controlling the quad from EZ-GUI

Phone call or message can bring EZ-GUI to background and you may lost control over your craft.

I bought CJMCU mini quad and I wanted to control it from my phone.

This is how I did it.
