Camera Setup

The default version of RoboFly has 2 cameras:

  • IMX296 mounted to the front, RGB global shutter camera
  • OV9281 mounted down, MONO global shutter camera

The IMX camera can be used as is, however the OV9281 needs to have the lens swapped and refocused. For camera install, you will need:

  • IMX camera
  • OV camera
  • 3D printed camera mounts
  • Longer lens holder for OV camera
  • Lens for OV camera
  • 2x M3 inserts (for 3D prints)
  • 2x M3x4 Bolts
  • 4x M2x8 Bolts and M2 nuts
  • 4x M2x10 Bolts and M2 nuts
  • 1x 150mm ribbon cable (For OV camera, the IMX camera comes with 150mm cable in the package)

Preparation​

  • Get the two 150 mm ribbon cables and connect them to Raspberry. Remove Raspberry from the drone for easier install.

  • Then connect the Raspberry back and route the cables through the board like this:

  • Remove the Lens holder on the OV camera by removing the two bolts in the back:

  • Replace the lens holder with the longer one. Be careful not to damage or contaminate the imaging chip!

  • While screwing the new mount, make sure to push it down to the side where the cable is not attached to the chip:

  • Once the mount is secured, take the new lens and screw it in. Be careful not to cross-thread! The focus will be adjusted later.
