DJI PHANTOM 4 PRO
CAMERA WITH 1-INCH 20MP SENSOR
The on-board camera has been redesigned to use a 1-inch 20-megapixel
CMOS sensor. A custom engineered lens made up of eight elements
is arranged in seven groups; it is the first DJI camera to use
a mechanical shutter that eliminates the rolling shutter distortion
which can occur when taking images of fast moving subjects or
when flying at high speed. In effect, it is as powerful as many
traditional ground cameras. More powerful video processing supports
H.264 4K videos at 60fps or H.265 4K at 30fps, both with a 100Mbps
bitrate. Advanced sensors and processors ensure everything is
captured with more image detail and the image data needed for
FIVE-DIRECTIONS OF OBSTACLE SENSING
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 five-directions
of obstacle sensing and four-directions of obstacle avoidance,
protecting the Phantom 4 Pro from more obstacles and giving filmmakers
the confidence to capture more complex images.
The Phantom 4 Pro controller integrates an upgraded Lightbridge
HD video transmission system that adds 5.8 GHz transmission support.
The ability to choose between 2.4Ghz and 5.8Ghz allows pilots
to cut through interference and eliminates image lag caused when
flying in an area with extensive 2.4Ghz frequency use. Normally,
Wi-Fi video transmission systems use a 2.4GHz frequency to work
with a controller using a 5.8GHz frequency as this prevents interference
that can occur when both use the same frequency. To perform normally,
the video transmission system and the controller will interfere
with each other causing image lag, especially if both use the
same frequency. The use of two different frequencies has drawbacks
in terms of flight performance. For example, flight performance
will be affected when either of the two frequencies suffers interference.
The Lightbridge HD video transmission system used in the Phantom
4 Pro uses TDM (Time Division Multiplexing) to transmit signals,
allowing it to send controller signals and receive video transmission
signals at the same frequency. As the 2.4GHz frequency band is
often affected by Wi-Fi, 4G cell towers, and other types of interference
in urban areas, a 5.8Ghz band will increase transmission reliability.
When switched on, the Phantom 4 Pro evaluates local signal levels,
automatically choosing the transmission frequency with the lowest
level of interference. This ensures the optimum range of a maximum
video transmission of 4.3mi (7km)*
*Unobstructed, free of interference, when FCC compliant.
Draw is a brand new technology for waypoint control. Simply
draw a route on screen and the Phantom 4 Pro will move in that
direction while keeping its altitude locked. This allows the pilot
to focus on camera control and enables more complex shots. There
are two Draw modes that can be used in different scenarios. Standard:
The aircraft follows the route at a constant speed with the camera
facing in the direction of flight. Free: The aircraft only moves
along the route when instructed. In this mode, the camera can
face in any direction during a flight.
The Phantom 4 Pro automatically recognizes subjects, follows and
captures them as they move, making it easier to get complex shots.
Following fast-moving objects can be very challenging, but advanced
image recognition algorithms used by the Phantom 4 Pro allow it
to recognize and track the object while keeping it in frame. This
new algorithm also recognizes more subjects, from people to vehicles
to animals, and will adjust its flight dynamics to match, ensuring
Pilots can now choose between:
Trace - Follow behind or in front of a subject, avoiding obstacles
Profile - Fly alongside a subject at a variety of angles to get
profile shots of the subject.
Spotlight - Keep the camera trained on a subject while the aircraft
flies almost anywhere.
Fly in any direction visible on-screen with a simple tap. Tap
anywhere on-screen to smoothly adjust the direction of flight
while automatically avoiding obstacles * and tap the screen again
or use control sticks to change direction. A new AR route function
shows the aircraft's real-time flight direction for reference
as its route is adjusted. As it can be difficult to control altitude,
course, speed and camera pitch simultaneously using joysticks,
TapFly Free allows a pilot to set the direction of flight, allowing
them to turn the Phantom 4 Pro or tilt the gimbal as required
without changing the direction of flight. In total, there are
now three TapFly modes:
TapFly Forward : Tap to fly in the selected direction
TapFly Backward : Tap to fly in the opposite direction of the
tap, i.e. tap in the bottom right corner of the screen to fly
backward towards the top left.
TapFly Free : Lock the forward direction of the Phantom without
locking the camera direction allowing it to turn as it flies.
*Obstacle Avoidance is not available with TapFly Free
RETURN TO HOME
In its upgraded Return to Home mode, the Phantom 4 Pro can automatically
choose the best route to return home depending on environmental
conditions. It records its route as it flies, allowing it to return
along the same route avoiding obstacles if the control signal
Based on its altitude at the time of disconnection, the Phantom
4 Pro is also able to adjust its flight path to avoid obstacles
it has seen during its flight. At take-off, the Phantom 4 Pro
will record the scene below and compare its recording with what
it sees as it returns, for more precise landing. It can also detect
the ground to see whether there is suitable spot for landing.
If any obstacles are found, or there is water on the ground, it
will alert the pilot and hover at an appropriate height, helping
the aircraft to land more safely.
Using Gesture Mode, selfies can be captured easily using a few
gestures without the remote controller. Advanced computer vision
technology allows the Phantom 4 Pro to take instructions through
gestures. The subject simply lifts their arms when facing the
camera and the aircraft will recognize this movement by locking
on and placing the subject in the centre of the frame. When ready
for a photo, the subject holds their arms out to signal the aircraft.
A three second countdown will begin, making time to strike a pose,
allowing moments to be captured without the remote control.
