Camera with 1-inch 20MP Sensor
The onboard 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 aperture that eliminates rolling shutter distortion that can occur when taking images of fast moving subjects or when flying at high speed and a mechanical focus.
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 advanced post-production.
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.
Six-camera navigation system
Three sets of dual vision sensors form a six-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 vison 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 50kph while avoiding obstacles in its path.
It will automatically adjust its obstacle detection method in line with its flight speed, allowing it to avoid obstacles at high and low speed.
What is FlightAutonomy
FlightAutonomy is an advanced aerial intelligence and flight automation platform.
It is made up of a complex network of ten component groups including seven cameras - forward, rearward and downward dual vision sensors and the primary camera - an infrared sensing system, dual-band satellite positioning (GPS and GLONASS), two downward facing ultrasonic rangefinders, redundant IMUs and compasses, and a group of powerful, specialized computing cores.
The Phantom 4 Pro acquires a real-time view of its environment and information about the height and position of nearby obstacles to create a 3D map it can locate itself within.
The IMU and compasses collect crucial flight status, speed and direction data, while redundant IMUs and compasses monitor critical data and rule out possible errors, dramatically enhancing the reliability of flight.
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 or when sensing uneven surfaces. 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.
Remote Controller with Built-in Screen
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 suffer 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.
A 5.5in 1080p screen integrated with the Phantom 4 Pro+ offers 1000 cd/m2 of brightness, more than twice as bright as conventional smart devices.
It makes bright, vivid colors easily visible in direct sunlight.
With this screen, a mobile device is not required, simplifying pre-flight preparations.
As the DJI GO app is built into the screen, hardware and software can be fully optimized, further reducing video lag.
Integration of an HDMI port, Micro-SD card slot, microphone, embedded loudspeaker, and Wi-Fi connection allow images to be edited inside DJI GO to be shared almost instantly. Lastly, a five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution.
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 smoother shots.
Pilots can now choose between:
Trace: Follow behind or in front of a subject, avoiding obstacles automatically.
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:
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 takeoff, 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 center 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.
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.
