On the night of February 9, at the opening ceremony of the 2018 Olympic Winter Games in Pyeongchang, South Korea, 1218 UAVs built the first UAV light show in the history of the Olympic Games. UAV carrying LED lights in the air to form a three-dimensional image of a skier, then change the formation, pieced together as "Olympic rings". The Guinness Book of World Records, which flew the largest number of drones at the same time, was born here.
The 1218 unmanned aerial vehicles were Shooting Star drones made by Intel Corporation of the United States, each weighing only 330 grams, a little heavier than volleyball. Intel explained that "the unmanned aerial vehicles that were unveiled at the opening ceremony were equipped with LED lighting devices that could show more than 4 billion color combinations when flying to the sky." There are media reports the UAV formation this time is not on-site control, but pre-recorded because of fear of Pyeongchang overly cold weather and unpredictable winds.
In fact, Chinese companies have also used quadcopter drone for similar performances. In December 2017, 1180 UAVs produced by Chinese companies made a spectacular and varied show in Guangzhou, forming different Chinese characters and patterns, setting a world record then. The live performance and the changing patterns make it more difficult to imagine the difficulty of the programming.
An authoritative Chinese expert on the field of drone said on the "Global Times" on the 11th that the key to fancy business performance is to be accurate and coordinated. The movements are pre-arranged, and according to the location of each individual UAV in accordance with their time and path of flight, you can display complex graphics in the air. In simple terms, there is no particularly complicated algorithm, and the main task is to have each UAV fly according to the path and time of the animation simulation. The UAV GPS signals or more accurate differential GPS signal will accurately locate the spatial location.
