Vision Systems and Three-Dimensional Infrared Sensing System
DJI Air 3 is equipped with both an omnidirectional vision system (forward, backward, lateral,
upward), the downward vision system, and the three-dimensional infrared sensing system,
which allows for positioning and omnidirectional obstacle sensing.
The omnidirectional vision system consists of four cameras which are located at the front and
rear of the aircraft. The downward vision system consists of two cameras, located at the bottom
of the aircraft. The vision systems sense obstacles by image ranging.
The three-dimensional infrared sensing system located at the bottom of the aircraft consists
of a three-dimensional infrared emitter and a receiver. The three-dimensional infrared sensing
system helps the aircraft to assess the distance to obstacles, the distance to the ground, and
calculate the aircraft position together with the downward vision system. The three-dimensional
infrared sensing system meets the human eye safety requirement for Class 1 laser products.
In addition, the Auxiliary Light located at the bottom of the aircraft can assist the downward
vision system. It will automatically turn on by default in low-light environments when the ight
altitude is under 5 m. Users can also turn it on or o manually in DJI Fly. Each time the aircraft is
restarted, the auxiliary light will revert back to the default setting Auto.
