They begin with the introduction of a stereoscopic detection system: based on the presence of 4 sensors in front and below the drone, it provides recognition of obstacles. The range of this system is 15 m at the front and 10 m below. Used in automatic mode, it allows the Phantom 4 to brake automatically in front of an obstacle until it stops to avoid the collision and, in the “Return to Home” mode, it allows to automatically return to its original position more efficient thanks to an optimization of its trajectory.
The intelligent functions of the Phantom 4 are operated in the “TapFly” autonomous flight mode. Simply specify the destination by clicking on the touch screen of the control box so that the drone goes there by adapting to its Environment and bypassing obstacles.
More interestingly, the DJI engineers worked on a tracking method called “Active Track”. The Phantom 4 will automatically follow a moving subject while leaving the user with control over camera movements as well as the ability to rotate around the subject that will always remain in the center of the frame. At any time, the user retains the possibility of pressing the “pause” button of the drone control to place it in the stationary position and resume control of the flight conditions.
Other features include “Sport” mode, which allows faster acceleration and deceleration of the Phantom 4 and a top speed of 20 m / s in flight. This speed can be reached thanks to the redesigned engines.
