Phantom 4 Advanced
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 FlightAutonomy system includes 5 vision sensors for 2-directions of obstacle sensing and forward-vision obstacle avoidance. The adoption of titanium alloy and magnesium alloy construction increases the rigidity of the airframe and reduces weight, making the Phantom 4 Advanced even lighter than the Phantom 4.
Camera With 1-Inch 20mp Sensor
The onboard camera is equipped with a 1-inch 20-megapixel CMOS sensor. A custom engineered lens made up of eight elements is arranged in seven groups. A mechanical shutter is used to eliminate 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. Excellent optical performance, sensors and processors ensure everything is captured with high dynamic range and more image detail needed for advanced post-production.
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 Advanced is almost 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.
Professional 4K Video
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 Advanced 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. Recording in the high dynamic range D-log mode makes the most of this image data for color grading.
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 Advanced 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. The MTF (Modulation Transfer Function) results have been made public, so people can get a better understanding of lens performance.
An MTF chart is used to measure the ability of a lens to reproduce contrast and resolve details. Low spatial frequencies reflect overall contrast, and high spatial frequencies reflect detailed resolution. Both are measured in LP/mm. Image Height indicates the distance of a given point on the lens from the center of the sensor. MTF 100% indicates perfect performance.
Capture Every Moment
Aerial imaging is used not only to capture landscapes but also to bring about new perspectives, like when filming action scenes and documenting motor racing. Capturing objects moving at high speeds has always been a challenge for flying cameras using electronic shutters. Phantom 4 Advanced uses a mechanical shutter and a large-aperture prime lens. A mechanical shutter with a max speed of 1/2000s eliminates rolling shutter distortion which can occur when taking images of fast moving subjects or when flying at a high speed. The electronic shutter has also been improved with a max shutter speed of 1/8000 seconds, and a new Burst Mode capable of shooting 14 fps at 20 megapixels, all to catch the perfect moment.
5 Vision Sensors
Equipped with the FlightAutonomy system made up of 5 vision sensors, dual-band satellite positioning (GPS and GLONASS), ultrasonic rangefinders and redundant sensors, Phantom 4 Advanced is able to hover precisely in places without GPS and fly in complex environments. The dual forward vision sensors can see as far as 30m out in front, and enable auto brake, hover or detour in front of obstacles within 15-meter range.
Draw is a brand new technology for waypoint control. Simply draw a route on screen and the Phantom 4 Advanced 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:
Following fast-moving objects can be very challenging, but advanced image recognition algorithms used by the Phantom 4 Advanced 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 accordingly, ensuring smoother shots.
Pilots can now choose between:
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 Advanced or tilt the gimbal as required without changing the direction of flight.
In total, there are now two TapFly modes:
Return to Home
In its Return to Home mode, the Phantom 4 Advanced 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 Advanced is also able to adjust its flight path to avoid obstacles it has seen during its flight. At takeoff, the Phantom 4 Advanced 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 a 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 Advanced 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, giving time to strike a pose, allowing moments to be captured without the remote control.
Different productions require different flight characteristics, and the Phantom 4 Advanced offers three modes for flight: P, A and S. 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 Advanced?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.
The Phantom 4 Advanced features dual compass modules and dual IMU units, making it more reliable. Compasses and IMUs are important sensors to ensure a stable flight and the Phantom 4 Advanced constantly compares the data it receives through both pairs. This data is run through advanced algorithms to check accuracy and any inaccurate data is simply discarded without affecting flight, keeping flight steady and reliable.
Professional aerial imaging benefits from longer flight times. The Phantom 4 Advanced has a maximum flight time of 30 minutes, providing more time in the air to capture the perfect shot. The DJI GO 4 app shows battery lifetime and calculates remaining flight time according to distance traveled and more. It will give alerts when it reaches a minimum safe amount required for a safe journey back to the takeoff point. An advanced battery management system is also in place to prevent overcharging and over draining. When placed in longer term storage, batteries will discharge power to maintain good health.
DJI GO 4
