When it comes to aerial photography, most users will think of nature's mountain view or city view. In recent years, more and more ultra-small drones have been launched, and the popularity of FPV racing machines has made indoor flight gradually become a topic of recent days. As for indoor flight, what should I pay attention to? The Drones Player reporter summed up 7 strokes of drone indoor flight secrets to share with you.
1. Flight sensor system on demand
Remember that Parrot's drones were the first to introduce indoor flight sensing systems, and DJI also added indoor flight sensing systems to individual models of the Inspire 1 and Phantom 3 series. The design of the two brands is similar, with the ultrasonic sensor + barometer set to the height, and the vertical video sensor instead of the GPS for positioning. The question is whether an indoor flight sensing system is required?
Parrot Bebop's indoor flight sensing system is primarily achieved by ultrasonic sensors.
If the flying hand itself has great flying experience, and the flying skills of the superior flying, then the use of the indoor flight sensing system is actually very similar, at most, it is only a little convenient for idle. However, for beginners, the indoor flight system can be said to be necessary, not to mention that the induction system is absolutely accurate, but at least there is a more reliable fixed height function, the flying hand can do as long as the direction is good, the operation is naturally much simpler.
The DJI Phantom 3's abdomen is equipped with ultrasound and video sensors to assist in indoor flight control.
2. Avoid repeating patterns or clear ground
As mentioned above, the indoor flight system is not 100% accurate. There are actually many restrictions. For example, a vertical video sensor for indoor positioning is operated according to whether the photographs are the same or not. How to make flight compensation. Therefore, if the indoor flight scene, the ground is a clear color or a repeating pattern, it is possible to deceive the positioning system, thereby invalidating the indoor positioning.
The carpet in the office is actually very easy to make the error detection system of the drone.
