Obstacle avoidance
• The drone’s obstacle avoidance (OA) system relies on stereo cameras, located on each side of the
main camera. Make sure the lenses of the stereo cameras are always perfectly clean: you can use a
drop of specialized (photo) lens cleaning liquid to ensure the cleanliness of the optics.
The OA system is activated through the Quick Settings and its status is displayed on the HUD, through a shield
icon in the top bar:
Grey:
OA deactivated
Green:
OA activated and operating optimally
Orange:
OA activated, degraded operation
Red:
OA activated, but inoperative
• In the following screenshot, the OA icon is green. Parrot strongly recommends deactivating the OA
whenever the icon is NOT green.
• If you see a “Stereo camera failure” notification associated with a red shield, deactivate the OA
immediately, land your drone as soon as possible and reboot all systems (drone, controller, app)
before attempting another OA activation: you may have to recalibrate the Obstacle avoidance system
before you can activate OA again – refer to the “Calibrations / Obstacle avoidance” section of this
guide for further information.
