Drone system for performance capable of realizing large-scale stereoscopic images

The present invention relates to a performance drone system capable of realizing large-scale stereoscopic images, and more particularly, by configuring a unit that flies in pairs with at least one main drone and a plurality of sub-drones to implement large-scale stereoscopic images by LED This enables stable implementation of colorful large-scale stereoscopic images in a performance system using multiple drones and eliminates spatial limitations. It relates to a drone system for performances capable of realizing large stereoscopic images that can lower the probability of failure of each drone and improve performance stability.

In general, drones have been used for military purposes such as manual flight by remote control of the ground control system or autonomous flight using a global positioning system (GPS), such as aerial photography or aerial strike. Due to the expansion of distribution and the development of control technology using mobile communication terminals such as smartphones, not only in the fields of high-altitude video or photo shooting and delivery, weather information collection, etc. It is used in various fields such as agricultural use for spraying pesticides for pest control, fire suppression use in high-rise buildings or deep mountains, and performance use to produce various performances in the sky.

Among them, in the case of a performance drone, a plurality of drones are being introduced to implement various performances necessary for a performance. By generating special effect substances, light is diffusely reflected by them to produce various performances.

However, in the case of the above drones for performances, various laser performances are performed by generating laser beams and haze or bubbles while flying in the sky. Since the image is displayed, the lighting effect or the three-dimensional effect using lasers and LEDs cannot be expressed in various ways. Therefore, in order to express images with more various types of lighting effects or three-dimensional effects, various types of peripheral devices are required, so the overall volume and area of the performance drone are enlarged by these peripheral devices. There was a risk that the drone would fall due to influence, etc. Also, as the power consumption increased due to the increase in the load burden, the battery usage time was shortened, which caused the flight time of the performance drone to be shortened.

In addition, recently, drone performances using tens or hundreds of drones are being conducted to perform large-scale performances. Because LEDs are driven, problems such as collisions or falls between drones due to communication or control errors have occurred. In addition, since small-sized drones are mainly used, the battery capacity is small, so the performance time or residence time is shortened. there was.
