14.0 Additional Instruction
14.1 Optical Flow Positioning System
Auto avoidance
Utilizing camera to get aircraft location information, it achieves
accurate positioning of aircraft. It is suitable for environments
with altitude of less than 3 meters without GPS signal or with
weak GPS signal.
Please make sure sufficient lighting of the environment and
rich patterns of the ground surface,
as the optical flow positioning system identifies position
variations based on the ground surface.
14.2 Infrared Obstacle Avoidance System
Less than 1m
Less than 5m
Auto decelerate
Less than 2.5m
Stop advance
8m
Rise up to 100m
The measuring accuracy of the optical flow positioning system tends to be affected by illumination intensity
and pattern of the ground objects, so please use this function under the circumstances below with caution:
Monochrome surfaces(eg pure black, pure white, pure red, pure green)
Highly reflective surfaces
Water or transparent surfaces.
Surfaces of moving objects(eg stream of people, shrub or grass)
Places where the illumination conditions dramatically change.
Extremely dark(less than 10 lux) or bright(more than 10,000 lux) surfaces
Surfaces without clear patterns
Surfaces with highly repetitive patterns(eg checker bricks with the same color)
The infrared obstacle avoidance system on the aircraft utilizes infrared sensors to detect nearby obstacles
and therefore automatically help the aircraft avoid obstacles.
However the aircraft is unable to avoid obstacles in manual or sports mode.
Hovering status in auto mode:
Obstacles avoidance available at forward, left and right.
Flight status in auto mode:
Obstacles avoidance available at forward, left and right.
Return home status:
forward obstacles avoidance only.
