The forward 3D infrared sensing system can sense the obstacles in the front. It will
activate automatically when the aircraft is in Normal or Cine mode and Obstacle
Avoidance Action is set to Brake in DJI Fly. The positioning function of the downward
vision system is applicable when GNSS signals are unavailable or weak.
Obstacle sensing is only available when manually controlling the aircraft to y forward
or during auto RTH. There is no obstacle sensing when using Intelligent Flight Modes
or Smart Snaps.
Notice
• Pay attention to the ight environment. The sensing system only works in
certain scenarios and cannot replace human control and judgment. During a
ight, always pay attention to the surrounding environment and the warnings in
DJI Fly, and be responsible for and maintain control of the aircraft at all times.
• If there is no GNSS available, the downward vision system will assist with aircraft
positioning, and works best when the aircraft is at an altitude from 0.5 m to 10
m. Extra caution is required if the altitude of the aircraft is above 10 m as the
vision positioning performance may be aected.
• The downward vision system may not work properly when the aircraft is ying
near water. Therefore, the aircraft may not be able to actively avoid water below
it when landing. It is recommended to maintain ight control at all times, make
reasonable judgments based on the surrounding environment, and avoid over-
relying on the downward vision system.
• The vision system cannot accurately identify large structures with frames and
cables, such as tower cranes, high-voltage transmission towers, high-voltage
transmission lines, cable-stayed bridges, and suspension bridges.
• The vision system cannot work properly near surfaces without clear pattern
variations or where the lighting is too weak or too strong. The vision system
cannot work properly in the following situations:
◆
Flying near monochrome surfaces (e.g., pure black, white, red, or green).
◆
Flying near highly reective surfaces.
◆
Flying near water or transparent surfaces.
◆
Flying near moving surfaces or objects.
◆
Flying in an area with frequent and drastic lighting changes.
◆
Flying near extremely dark (<15 lux) or bright (>10,000 lux) surfaces.
◆
Flying near surfaces that strongly reect or absorb infrared waves (e.g.,
mirrors).
