Using the Vision Systems
When GNSS is unavailable, the Downward Vision System is enabled if the surface has a clear texture
and sucient light. The Downward Vision System works best when the aircraft is at an altitude of 0.5 to
30 m.
The Forward, Backward, and Upward Vision Systems will activate automatically when the aircraft
is powered on if the aircraft is in Normal or Cine mode and Obstacle Avoidance is set to Bypass or
Break in DJI Fly. Using the Forward, Backward, and Upward Vision Systems, the aircraft can actively
brake when detecting obstacles. The Forward, Backward, and Upward Vision Systems work best with
adequate lighting and clearly marked or textured obstacles.
Vision Systems have limited ability to sense and avoid obstacles, and the performance may be
affected by the surrounding environment. Make sure to maintain visual line of sight with the
aircraft and pay attention to prompts in DJI Fly.
The max hover altitude of the aircraft is 60 m if there is no GNSS available. The Downward Vision
Systems work best when the aircraft is at an altitude from 0.5 to 30 m. Extra caution is required if
the altitude of the aircraft is above 30 m as the Vision Systems may be affected.
The Auxiliary Bottom Light can be set in DJI Fly. If set to Auto, it is automatically enabled when
the environment light is too weak. Note that the Vision System cameras performance may be
affected when the Auxiliary Bottom Light is enabled. Fly with caution if the GNSS signal is weak.
The Vision Systems may not function properly when the aircraft is ying over water or snow-covered
areas.
The Vision Systems cannot work properly over surfaces that do not have clear pattern variations.
The Vision Systems cannot work properly in any of the following situations. Operate the aircraft
cautiously.
a. Flying over monochrome surfaces (e.g., pure black, pure white, pure green).
b. Flying over highly reective surfaces.
c. Flying over water or transparent surfaces.
d. Flying over moving surfaces or objects.
e. Flying in an area where the lighting changes frequently or drastically.
f. Flying over extremely dark (< 10 lux) or bright (> 40,000 lux) surfaces.
g. Flying over surfaces that strongly reect or absorb infrared waves (e.g., mirrors).
h. Flying over surfaces without clear patterns or texture.
i. Flying over surfaces with repeating identical patterns or textures (e.g., tiles with the same design).
j. Flying over obstacles with small surface areas (e.g., tree branches).
Keep the sensors clean at all times. DO NOT tamper with the sensors. DO NOT use the aircraft in
dusty or humid environments.
