Introduction – Are You Following Me?
Picture the scene: you’re just about to reach the top of the mountain. The golden hour lighting is totally sublime. As you attain the height, you’ve got the framing good to seize the dramatic sunset. But all of a sudden you realize you can’t really get the epic shot of your self that you just envisaged as a end result of you’re too busy controlling the drone.
To overcome this, drone producers have developed automation options that take out lots of the guesswork and are making aerial images increasingly intuitive. Drones that follow you allow you to benefit from your adventure without the worry of crashing the one that you love drone because you’re too targeted on where you’re going. Let’s transfer on to take a look at how comply with me drones really work, what the distinction is between fashions, and which is comes out on top.
1. How Do Follow Me Drones Work?
Drones that comply with you are in a position to autonomously track a goal, without having to be piloted. Currently there are two major applied sciences which may be used in the observe me feature, most commonly found in quadcopter drones, and so they work in several methods to permit drones to trace objects autonomously and accurately.
The earliest comply with me drones had been programmed to observe a GPS transmitter or Ground Station Controller (GSC) that customers had to wear. This created a virtual tether between the person and the drone. This GPS transmitter is often constructed into the distant controller, which then becomes required for the drone to follow you.
DJI first launched comply with me drones in 2015 with the Phantom 3 collection. Its huge array of Intelligent Flight Modes embody Follow Me, Course Lock, Waypoints, Home Lock, and Points of Interest. As with different GPS-based drones, the Phantom 3 requires a remote controller and the DJI GO app to enable Follow Me mode.
So why use GPS tech? The monitoring accuracy of GPS tech is unrivaled, offering a lot better precision than other techs. However, a tracker/transmitter is all the time required for the system to work and impediment avoidance is not a function.
2) Vision Recognition Tech
Detecting objects, folks, and obstacles by way of data captured by a digicam has been used in robotics for the explanation that early 2000s. Due to its excessive requirements on computing, battery life, and security, the tech has solely been utilized in drones for the earlier few years.
In basic, the imaginative and prescient recognition technology works as follows:
* The drone cameras and sensors collect image and sound information, which is then transmitted to the processor.
* With enough knowledge, the processor identifies the background elements of the scene and locates any shifting objects.
* As programmed, the plane starts to automatically observe the transferring object.
Thanks to current technological advances, this whole three-step course of can now be completed within a matter of seconds on the most recent models.
Besides speedy response time, vision recognition additionally has the advantages that it is able to monitor all kinds of moving objects, including automobiles, bikes, individuals, and animals, and does not require an exterior GPS tracker, as a substitute utilizing suitable software/app on the controlling device. Recognition accuracy, nevertheless, can be affected by lighting circumstances and the contrast between areas in direct mild and those in shadow.
To overcome the constraints of GPS and imaginative and prescient recognition methods, DJI mixed the two applied sciences into the ActiveTrack system, realizing the best of both approaches.
2. On Track With DJI’s ActiveTrack
The ActiveTrack function was first introduced with the Phantom four collection and represents the evolution of the Follow Me mode discovered on previous drones, vastly improving accuracy and person experience. It permits the consumer to mark and observe a quantity of moving objects on the controlling device’s screen without the necessity of an exterior monitoring device.
Both GPS and vision recognition are utilized in the ActiveTrack feature to locate the drone itself, stabilize its flight, and navigate between obstacles. It has been such a success that it’s out there on virtually all new drones released by DJI. The DJI GO four app has been specifically launched for use with ActiveTrack, as shown right here:

Although impediment avoidance options are an excellent tool in flight safety, it is always advisable to maintain the following flight safety tips in mind when flying a observe me drone:
* Flight altitude: In comply with me modes, a sure minimal flight peak may be required in specific drone models. We advocate setting the drone’s flight altitude to be higher than surrounding obstacles.
* Fly in an open house: Although the drones can avoid obstacles in front of and beneath the aircraft utilizing Intelligent Flight modes, they are unable to avoid obstacles above, beside and behind the drone. Therefore, fly the drone in an open space and be sure that there are no obstacles to the side or behind the drone.
* Be sure to fly in P-mode: DJI’s ActiveTrack feature requires each the GPS signal power and the imaginative and prescient recognition system, which is only out there when flying in P-mode. When you turn the flight to S-mode, the aircraft only uses GPS to locate itself. The ahead and backward vision techniques (when equipped) are disabled, the aircraft is not in a place to sense or avoid obstacles, and Intelligent Flight modes are unavailable. The aircraft mechanically changes to Attitude mode (ATTI mode) when the vision techniques are unavailable or disabled and when the GPS sign is weak or the compass is experiencing interference. In this case, the aircraft isn’t able to keep away from obstacles and is a potential flight hazard.
* Battery status: Remember to regulate battery levels and warnings. Do not try to use the observe me modes on low battery. We counsel flying in ActiveTrack mode with no much less than 30% battery energy remaining.
