EVO Nano Series User Manual

Remark

If the calibration fails, the indicator light behind the aircraft will flash red, and the APP
will also prompt that the calibration is failed. Repeat above steps.
 Please keep away from the metal or electric object, and maintain the aircraft at about
1.5m above the ground.
2.7 Binocular vision system
The front, rear and downward binocular vision perception system of EVO Nano series uses
image data to calculate the distance between the aircraft and potential obstacles. Once an
obstacle is detected, the system will stop the aircraft. An ultrasonic sensor is also installed
under the aircraft, which can provide the altitude reference of the aircraft to the ground and
cooperate with the vision system to calculate the aircraft position information.
