What is the performance of DJI Elf 4 Phantom 4 UAV?

DJI Mirage 4 UAV 1, brand-new materials and stronger maneuverability.

? Brand-new magnesium alloy movement design reduces the weight and increases the strength of the fuselage, thus effectively eliminating mechanical vibration. The new core structure makes the center of gravity of the aircraft closer to the propeller plane, which enhances the overall stability and maneuverability of the aircraft.

Phantom 4' s streamlined body not only makes people shine, but also provides excellent aerodynamic performance. Exquisite structural technology and surface treatment reduce the wind resistance of the fuselage. The pan/tilt adopts integrated design, which is closely combined with the fuselage, and the weight of the fuselage is concentrated inside, further improving the stability. Whether flying or shooting, it can achieve rapid response and precise control.

2. Multiple flight modes

? Switch flight modes to meet the needs of different scenes, whether you need convenient intelligent flight, smooth manual aerial photography or high-speed crossing, Phantom 4 can meet it. Phantom 4 can meet different flight preferences and application scenarios. Positioning mode provides pointing flight, intelligent following, obstacle perception and intelligent positioning functions; Motion mode gives Phantom higher sensitivity and speed; Attitude mode provides attitude stability and turns off satellite positioning to achieve more flexible and smooth aerial photography.

3. Longer battery life and longer control.

? The flight time of Phantom 4 is 28 minutes, and the effective flight time is increased by about 25% compared with the previous generation. The distance between image transmission and flight control is as far as 5 kilometers, allowing you to fly freely and take pictures calmly.

Efficient power system and 5350mAh high-capacity smart battery provide Phantom 4 with a battery life of up to 28 minutes. Advanced power management system protects the battery through intelligent charging and discharging, ensuring safer and lasting use. Built-in DJI Lightbridge HD video transmission system can transmit the images of aircraft cameras within 5km to eyes with 720p HD quality. The optimization of signal technology greatly reduces interference and delay, allowing you to obtain aircraft information in real time and realize precise control.

These data were measured in uniform flight.

The distance is measured in an undisturbed outdoor open space and adjusted according to the actual requirements of local laws and regulations.

DJI Mirage 4 UAV Vision 1, Environment Perception and Obstacle Avoidance

? The forward-looking obstacle perception system integrates advanced sensors and computer vision technology, which makes Phantom 4 have the ability of perception and active obstacle avoidance. Brand-new visual down-looking positioning system, the effective distance 10 meter, which is more than three times higher than the previous generation, allows you to hover accurately and fly stably in indoor and other environments without GPS signal.

? See? The world interacts with it, and the forward-looking obstacle perception system gives Phantom 4 the depth perception ability of three-dimensional space. In normal flight mode, the aircraft will automatically hover when it senses obstacles. In the process of pointing flight, intelligent following and intelligent returning, it can also make its own judgment and choose to hover or bypass obstacles to continue flying according to the environment. Obstacle perception is prompted by the app, so that you can know the flight status at any time. The visual positioning system consists of binocular vision sensors and a group of ultrasonic sensors. It takes effect when the flying altitude is lower than 10 meter, and the visual positioning system can enhance the hovering accuracy and flight stability. Phantom 4 can provide a smooth flight experience even indoors and in other environments without GPS signals.

2. Point to flies

? In the pointing flight mode, click on the screen of the mobile device, and Phantom 4 can fly in the direction you choose. When it senses an obstacle, it will automatically hover or bypass the obstacle according to the environment.

With a touch, the plane can understand your intention. Phantom 4 adopts the most intuitive and convenient control method, and there is no need to control the joystick. Click on the screen in pointing flight mode, and the plane can fly in the direction you choose. Click on other areas of the screen to change the route. It is a challenge to control the altitude and heading of an aircraft at the same time with a rocker and fly in a straight line at a constant speed. Pointing flight not only solves this problem, but also allows you to concentrate more on shooting composition during flight. With the obstacle sensing function, Phantom 4 can get close to the cliff or go through the forest, and you can shoot a more dynamic high-speed picture by just touching the screen. Through the app, you can also achieve intelligent return. The new reentry function adds obstacle perception and automatic height adjustment technology to make the flight safer.

3. Visual tracking

? Advanced intelligent follow-up technology makes Phantom 4 your personal photographer. It can identify and track the subject in the camera picture without using a tracker such as a bracelet, and lock it in the center of the picture.

Phantom 4 turns scenes from science fiction movies into reality. Whether doing morning exercises on the path, driving on the road, or rowing in the rapids, the plane can be recognized by the camera and automatically follow. Flying around moving objects is also a challenge for professional flying hands. Phantom 4 will lock the subject in the center of the picture during the follow-up process, so you can shoot left and right or adjust the follow-up height and distance by gently pushing the joystick. In intelligent follow-up, the aircraft can also perceive the obstacles ahead and automatically choose to hover or bypass.
