A collaborative safety flight control system for multiple drones: dealing with weak wind by changing drones formation

Abstract

In recent years, it has become possible for anyone to purchase high-performance Drones at low price. The Drones are equipped with a unit of high-vision camera, multiple compact cameras for flight control, gyroscope, infrared sensor, GPS, and a processor for processing video images and sensor information for controlling the flight. Relatively stable flight is available for Drones by operating within human’s sight. In this paper, we introduced our collaborative security flight control system for multiple drones. We considered the case of weak wind. To deal with weak wind, we propose that the drones change the formation. We added the Caution level for the safety level. In the case of weak wind, the Caution level is activated and the drones change the position (formation) in order to keep the distance between them.
