Vision Systems and 3D Infrared Sensing System
DJI Mini 4 Pro is equipped with both an omnidirectional vision system (forward, backward,
lateral, upward), downward vision system, and 3D 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 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 3D infrared sensing system on the bottom consists of a 3D infrared emitter and a receiver.
The 3D 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 3D infrared sensing system meets the human eye safety requirement for Class 1
laser products.
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 flight altitude is
under 5 m. Users can also turn it on or o manually in the DJI Fly app. Each time the aircraft is
restarted, the auxiliary light will revert back to the default setting Auto.
