DJI Releases Phantom 4 Pro

So DJI released Phantom 4 Pro and Inspire 2 today. The key attraction here is Phantom 4 Pro though. It now has 5 way obstacle sensing with rear vision sensors and IR sensors on either side of the drone. The only direct it lacks by the looks of it is upward.

The camera seems to be vastly improved as well with adjustable aperture and mechanical shutter with a larger sensor. It now supports H.265 format and recording 4K @ 60 fps at 100Mbps which translates into more details than ever compared to P4 and P3P.

A point of interest is that it uses Lightbridge instead of new OccuSync they introduced with the Mavic which makes me wonder. There's also a P4 Pro+ version that comes with a 5.5" ultra bright display built in to the RC which would make sense for some.

It's retailing at US $1499 but down under price is AU $2599 as expected. Here's the details straight from the DJI forums.

Product Summary

An uprated camera is equipped with a 1-inch 20-megapixel sensor capable of shooting 4K/60fps video and Burst Mode stills at 14 fps. The adoption of titanium alloy and magnesium alloy construction increases the rigidity of the airframe and reduces weight, making the Phantom 4 Pro similar in weight to the Phantom 4. The FlightAutonomy system adds dual rear vision sensors and infrared sensing systems for a total of five-directions of obstacle sensing and four-directions of obstacle avoidance.

The Phantom 4 Pro camera system has been significantly upgraded from the Phantom 4, improving every part of the camera including, sensor size, resolution, image processing system, and more, making it the most powerful Phantom camera ever.

1-inch 20-megapixel CMOS

Sensor size is more important to image quality than the number of pixels because a larger sensor captures more information in every pixel, improving dynamic range, signal-to-noise ratio, and low light performance. The 1-inch 20-megapixel CMOS sensor in the Phantom 4 Pro is four times the size of the Phantom 4's 1/2.3in sensor. It uses larger pixels and has a maximum ISO of 12800 as well as increased contrast. It is good enough for images to be used immediately, while also capturing enough detail for advanced post-processing.

Production optimized 4K

An enhanced video processing system allows video to be captured in cinema and production optimized DCI 4K/60 (4096 x 2160/60fps) at a bitrate of 100Mbps, enabling you to get high-resolution slow motion shots. The Phantom 4 Pro also supports the H.265 video codec (Maximum resolution 4096X2160/30fps). For a given bitrate, H.265 doubles the amount of image processing as H.264, resulting in significantly enhanced image quality. Record in the high dynamic range D-log mode to make the most of this image data for color grading.

High resolution lens

The resolution and contrast of a lens is critical to image quality, because only a quality lens can capture sharp, vivid photos at high resolutions. The brand new Phantom 4 Pro camera has an aerial optimized F2.8 wide-angle lens with a 24mm equivalent focal length. It features eight elements – 2 aspherical – arranged in seven groups that fit into a smaller, more compact frame. Its images are consistently detailed with low distortion and low dispersion, ensuring that photos and videos are sharp and vivid. For the first time ever with a DJI camera, MTF (Modulation Transfer Function) results for this camera have been made public, so people can get a better understanding of lens performance.

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.

Pilots always need to be aware of obstacles when shooting from the air. This is a challenge for beginner pilots as well as experienced pilots, especially when sight lines are obstructed. The Phantom 4 Pro is equipped with an environment-sensing system based on stereo vision sensors and infrared sensors. It is able to detect obstacles 98ft (30m) in front, allowing it to plan its flight path to avoid them or simply hover in the event of an emergency. This same system also allows it to hover in position without GPS. Combined with infrared sensors on its left and right sides, the Phantom 4 Pro can avoid obstacles in a total of four directions. Forward and rearward obstacle sensing range has been increased, allowing the Phantom 4 Pro to fly at 31mph (50kph) with full protection of its stereo vision obstacle sensing system. It makes fast, dramatic video easier and ultimately safer to capture.

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 31mph (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. This ensures the optimum range of a maximum video transmission of 4.3mi (7km)*.

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.

Intelligent Flight

Drones are becoming easier and easier to control, but the piloting experience remains essential for quality aerial imaging. Using DJI’s machine vision and depth learning technologies, the Phantom 4 Pro transforms complex aircraft movements into simple orders, significantly simplifying aerial creativity. In contrast with satellite positioning based intelligent flight functions, Intelligent Vision enhanced flight ensures precision camera view and control.

Draw

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.

ActiveTrack

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.

TapFly

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 is disconnected.

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.

Gesture Mode

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.

Flight Performance

Flight modes

Different productions require different flight characteristics, and the Phantom 4 Pro offers three modes for flight: P, A and S. Switching between them allows pilots to get the control they need, whether they seek smoothness, simplicity, intelligent navigation or speed. In Position Mode, TapFly, ActiveTrack, obstacle sensing and positioning features are available. Sport Mode adds extra agility and higher speed, reaching 45mph (72kph). Atti Mode switches off satellite stabilization and holds the Phantom 4 Pro’s altitude. It is ideal for experienced pilots looking to capture smoother footage. Tripod Mode, which limits speed to 4mph (7kph) provides precision control for fine framing and indoor flying. Both the infrared sensing system and vision sensors are enabled in these modes for a safer flight experience.

4.3mi (7km) long-range control

Using brand new DJI Lightbridge HD video transmission technology, the Phantom 4 Pro has a maximum transmission range of 4.3i (7km)*. Before each flight, it scans a range of available frequencies to find and use the one with the least interference. By supporting 2.4GHz and 5.8 GHz frequency bands, it gives you more reliable control. Tightly integrated with DJI GO, Lightbridge video transmission also sends vital flight statistics in real time, and can be used to quickly download photos and videos to connected mobile devices.

The Lightbridge video transmission system uses advanced transmission technologies and can automatically adjust to environmental conditions. It ensures high quality, low latency image transmission across its range and offers pilots a better shooting experience. Traditional analog video transmission occupies a larger bandwidth and is more susceptible to interference. It also suffers from poor image quality and short range. Wi-Fi transmission also compares poorly, suffering from low latency, lengthy re-connection times, and short transmission distances due to the high cost of more powerful Wi-Fi transmission.

TL;DR: Anybody excited about DJI Phantom 4 Pro? Oh and the cherry on top is that they will actually ship it within 24hrs of the order unlike the Mavic.
