Description

A method and system for controlling video shooting of a plurality of drones {SYSTEM and METHOD FOR controling multiple drone camera and video proccessing}

The present invention relates to a method and system for controlling image capturing of a plurality of drones, and more particularly, by controlling the image capturing operation of a plurality of drones in formation with one monitoring terminal, it is possible to easily control a plurality of drones at once and , It relates to a method and system for controlling image capturing of a plurality of drones, which can effectively acquire and manage image information captured at various viewpoints by a plurality of drones as the captured images are displayed on one monitoring terminal.

Initially, the drone industry market was developed to be used for military purposes between countries, but recently, it has been expanded to various industrial fields such as industrial video shooting, disaster monitoring, agriculture, logistics, and broadcasting rather than military use, which is the initial development purpose. The industrial drone market has rapidly expanded worldwide, and in particular, in Korea, when an emergency disaster occurs centered on the Fire and Disaster Headquarters, the drone system is used as a disaster safety response solution that can quickly identify emergency disaster sites. . In particular, it is used as an important means to obtain the necessary image by approaching the location of the disaster site that is difficult to access by putting a drone into the scene in case of a disaster, but it is not easy to manipulate the image taken with the drone put into the disaster site. .

Above all, in a disaster situation, several drones are deployed at once to shoot images. When shooting images while flying in a formation or stationary in the air, one drone needs to be monitored and controlled by a single terminal, so multiple drones are required. In the case of input, several terminals are required. Therefore, in the case of controlling the image capturing of the drone using multiple terminals, it is often not possible to obtain a necessary image or accurately obtain necessary information. Accordingly, a separate monitoring terminal was required for each drone, and the inconvenience of monitoring several terminals occurred. In addition, as the drone re-flyed to film again, disaster situations such as fires were further aggravated by failure to grasp the disaster situation within the golden time.

Therefore, in order to solve the above problems, there is a need for a technology capable of manipulating image capturing of a plurality of drones with one terminal and efficiently managing the plurality of images.
