DJI Phantom 4 Pro drone

dji-p4-pro

The DJI Phantom 4 Pro is the new version of the DJI Phantom 4, it is one of the Phantom family. As the youngest member of DJI Phantom, what are the difference to others? Next let’s know more about DJI Phantom 4 Pro.

DJI Phantom 4 Pro

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 Flight Autonomy system adds dual rear vision sensors and infrared sensing systems for a total of 5-direction of obstacle sensing and 4-direction of obstacle avoidance.

4K Camera

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 shutter, eliminating 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 advanced post-production.

5-Direction of Obstacle Sensing

Flight Autonomy 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.

Flight Autonomy Technology

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.

Intelligent Flight

DJI Phantom have five Intelligent Flight characteristics;

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.

Active Track

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. This feature like the Wings land S6 drone, the “follow me feature”.

Tap Fly

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.

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.

About the battery of DJI Phantom 4 Pro, it used 4s lipo battery, and the battery’s capacity about 5870 mAh, if your battery is broken, you must go to their online shop to buy a new one, it seemed you can use the other brand lipos. But nothing is absolute, like my iPhone battery, I also use other brand battery to replace it, so as DJI Phantom 4 Pro lipo battery, you can find a battery which can replace the DJI official battery.

DJI Phantom 4 Pro is a beautiful and useful drone, and is is very popular over the world, if you want to buy a drone, DJI Phantom 4 is a good choose, but the price is not cheap. But you can try to read this articleWingsland S6 UHD 4K intelligent camera handheld drone ; this is a cheap mini pocket drone.
