DJI Phantom 4 Pro autonomous and obstacle avoidance features:
Improved 5 direction FlightAutonomy obstacle sensing system
FlightAutonomy in the Phantom 4 Professional has been greatly improved and now features 5 directions of obstacle avoidance. This obstacle avoidance system is made up from a complex network of ten component groups including seven cameras; forward, rearward; side infrared sensing systems; downward dual vision sensors; the primary camera; 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 new infrared sensing systems sensors have a horizontal field of view of 70°, a vertical field of view of 20°, and a maximum range of 7m, providing a wide view of the scene to the sides of the Phantom 4 Pro. These infrared systems replaced the traditional ultrasonic sensors because they only have a detection range of 3-5m and may be confused when affected by propeller vibration or when sensing uneven surfaces.
Together all these components renders an accurate 3D environment (up to 30m) around the DJI P4 Pro and monitors critical data and rule out possible errors so it can react to its surroundings. This obstacle avoidance system works both in outdoor and indoor environments and is activated in every Intelligent Flight Mode including all ActiveTrack modes, TapFly and Terrain Follow. It is also available during automatic Return to Home, and the drone will follow its flown path back while dogging obstacles to return safely in case of a lost connection or low battery.
ActiveTrack subject follow and framing with 3 modes
The DJI Phantom 4 Professionals ActiveTrack successfully makes autonomous/automatic follow recording a reality. Whether you or your subject are running, cycling, skating, skiing, driving, the Phantom 4 Professional uses an advanced combination of computer vision, object recognition, gesture support and machine learning to track as your subject moves. Circling a moving object and keeping it in frame used to only be achievable by the most confident of pilots, now thanks to completely autonomous following and flight speeds of up to 72kmph everyone can do it. A new algorithm also recognizes more subjects, from people to vehicles to animals, and will adjust its flight dynamics to match, ensuring smoother shots.
New ActiveTrack flight modes opens new creative tracking including Trace, a follow mode behind or in front of a subject; Profile, for tracking alongside a subject at a variety of angles to get profile shots of the subject; and Spotlight, a mode that keeps the camera trained on a subject while the aircraft flies almost anywhere. The entire time ActiveTrack is running obstacle avoidance is too, so it will decide whether it should continue following, avoid an obstacle or simply stop.
You don't have to manually fly the DJI Phantom 4 with the control sticks, TapFly takes over all of these controls for you leaving you to focus on your shot. Using TapFly mode, all you have to do to is tap on the screen of your smartphone or tablet and the Phantom 4 Pro will fly there. To change the direction of flight, you can simply tap the screen to fly anywhere. Using its Flight Autonomy Obstacle Sensing System, the DJI Phantom 4 can fly places you might not have gone before, to create dynamic and inspiring footage.
Auto-return home with FlightAutonomy
The DJI Phantom 4 Professional features a failsafe auto-return home feature and will automatically return to the exact spot it took-of if it detects that the battery is running low, connection to the controller is lost or if the return home button is pressed. The drone will follow the exact flown path back with the FlightAutonomy obstacle sensing system to safely guide the drone past moving/moved obstacles.
