FlightAutonomy is expanded with an additional set of high-resolution stereo vision sensors placed at the rear in addition to the pair placed at the front
as well as infrared sensing systems placed on the left and right sides. This network creates a total of 5-direction of obstacle sensing and 4-direction of
obstacle avoidance, protecting the Phantom 4 Pro from more obstacles and giving filmmakers the confidence to capture more complex images.
6-CAMERA NAVIGATION SYSTEM
Three sets of dual vision sensors form a 6-camera navigation system that works constantly to calculate the relative speed and distance between the
aircraft and an object. Using this network of forward, rearward and downward vision sensors, the Phantom 4 Pro is able to hover precisely in places
without GPS when taking off indoors, or on balconies, or even when flying through windows with minimal pilot control. In the unlikely event that front
and downward sensors are unable to operate, the aircraft can still hover in place using the rear stereo vision system. The Phantom 4 Pro also is able
to fly in complex environments at a flight speed of up to 31mph (50kph) while avoiding obstacles in its path. In Narrow Sensing Mode, the Phantom 4
Pro narrows its sensing scope enabling it to see in more detail and fly through small spaces.
INFRARED SENSING SYSTEM
The Phantom 4 Pro is the first DJI aircraft to use an infrared sensing system. Placed on the left, and right sides of the aircraft, these measure the
distance between the aircraft and any obstacles using infrared 3D scanning. When in Beginner Mode and Tripod Mode, these sensors have a
horizontal field of view of 70° and a vertical field of view of 20°, providing a wide view of the scene to the sides of the Phantom, and a maximum
range of 23ft (7m). Traditional ultrasonic sensors only have a detection range of 3-5m and may be confused when affected by propeller
vibration. The infrared sensing system is able to sense larger areas and measure the distance between the aircraft, identifying the
closest objects accurately while avoiding interference, providing more reliable sensing and protection.
