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 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.
CAPTURE EVERY MOMENT
Aerial imaging is not only used to capture landscapes; it brings new perspectives to everything from action scenes to motor racing. Capturing objects moving at high speed has always been a challenge for flying cameras using an electronic shutter. This is why the Phantom 4 Pro is the first DJI Phantom to use 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 high speed. The electronic shutter has also been improved with a max shutter speed of 1/8000 seconds, and a new Burst Mode shoot capable of shooting 14 fps at 20 megapixels to catch the perfect moment.
5-DIRECTION 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 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.
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.
