12000 drones soared into the sky, using the sky as a curtain and light as a pen, painting imagery patterns such as "Ruzi Niu" and "Shenzhen Heart"... To celebrate the 45th anniversary of the establishment of the Shenzhen Special Economic Zone, a grand drone light show performance was held simultaneously at 8:26 pm on August 26th at the two main venues of Shenzhen People's Square and Shenzhen Talent Park in Guangdong Province. At the Talent Park, the "Window of the Future" technology exhibition showcases the international expression of "Amazing Shenzhen" through drones, the transformation of landmark buildings into "spatial rings", the names of Shenzhen enterprises, and the passionate beating of the "Heart of Shenzhen", showcasing the vibrant vitality and innovative charm of Shenzhen; At the Civic Square, the theme performance of "The Road to Reform" pays tribute to the struggle history of the special economic zone, such as "The Wind Rises in the South China Sea" and "Crossing the Mountains and Seas Again", through chapters such as "The Wind Rises in the South China Sea" and "Crossing the Mountains and Seas Again". The on-site audience responded enthusiastically. Ms. Kuang, who came all the way from Hunan, sighed, "The experience of filming videos and watching live broadcasts is far less shocking than the one in ten thousand on-site!" She made an appointment in advance and waited for a long time before successfully "grabbing" the opportunity to enter. Mr. Lin, a local from Shenzhen, spoke proudly: "Such a large-scale performance makes people both happy and proud!" Behind the visual shock is the blessing of drone performance technology. It is not only the world's first to achieve synchronized flight of dual matrix and 10000 level drones, but also relies on the "1+2+N" mode to link 16 light shows, achieving the grand effect of a "city stage". Behind the magnificent presentation of drone formation performances is a precise industrial process from artistic creativity to technical execution. It all started in the design phase, where designers used some commonly used software to transform their ideas into a dot matrix composed of countless dots - each drone flying into the sky itself is a glowing pixel, ensuring precise effects. ”Qin Haiqun, Deputy General Manager and Director of Technical Support Department of Shenzhen Desert Intelligent Control Technology Co., Ltd., told reporters. Of course, in order to achieve more creative 3D dynamic modeling, the team also needs to conduct 3D modeling and use professional animation software to achieve smooth transformations in the model. Subsequently, these independent patterns, models, and animations were linked together to form a complete 'performance script'. The most technically challenging aspect is' route planning ', which involves using complex algorithms to automatically calculate the optimal path for thousands of drones to safely and efficiently fly from the previous pattern location to the next pattern location. The core task of the algorithm is to ensure that no two drones collide in the ever-changing formation, while also meeting strict engineering parameters such as speed and acceleration. ”Tan Haiqun said. Qin Haiqun introduced that there are three core technologies behind this: firstly, communication technology, which ensures that all drones can maintain stable and uninterrupted connections with ground stations and synchronously receive commands; Secondly, the evolution of intelligent algorithms requires powerful algorithms to achieve global collaboration and obstacle avoidance; Finally, there is the innovation of high-precision positioning technology. In the early days of relying on GPS, the positioning accuracy was only about 2 meters, and planes had to maintain a safe distance of more than 5 meters between each other, which made large patterns extremely loose. Nowadays, by using centimeter level positioning technologies such as RTK (Real Time Kinematic), the spacing between drones has been successfully reduced to 1.4 to 1.5 meters, presenting unprecedented precision and stunning visual effects. In this performance in Shenzhen, we extended the originally planned 15 minute drone show to 30 minutes in order to allow citizens to watch it all at once. ”Qin Haiqun revealed that under the reality of the inability to achieve breakthroughs in single battery life, the team proposed a multi tiered relay solution of "exchanging quantity for time". For example, 6000 aircraft are divided into several tiers, with the first tier taking off to perform, followed by the second tier taking over, and the first tier returning to land before the third tier takes off, like an "aerial relay race". The wonderful performance has ignited the local cultural and tourism industry. According to preliminary statistics, on the day of the event, the cultural and tourism consumption scale in Shenzhen exceeded 1.2 billion yuan, the passenger flow in the commercial district increased by 30% year-on-year, and the number of overseas tourists increased by 15%, both higher than the data during last year's National Day 10000 drone performance. We will innovate by jointly planning and promoting 'watching shows+consumption', and through cross industry and cross departmental collaboration, we will use a combination of promoting consumption and unlocking new economic vitality. ”Zhang Qi, Director of the Tourism Promotion Department of Shenzhen Municipal Bureau of Culture, Radio, Television, Tourism and Sports, introduced. Around this drone light show performance, Shenzhen has formed a chain of food, accommodation, transportation, travel, shopping, and entertainment. The Municipal Bureau of Culture, Radio, Television, Tourism and Sports, in conjunction with the "Shenzhen Summer Surprise" brand, has partnered with over 80 hotels to launch consumer promotion activities; Futian District integrates ten major commercial districts to launch a "Slightly Drunken Futian" themed promotion, achieving "one code smooth enjoyment and discount interconnection"; Nanshan District has issued a 10 million yuan cultural and tourism consumption subsidy, and collaborated with Nanshan Museum to launch the "Exhibition Enjoy Accommodation Discounts" activity, effectively converting the flow of spectators into consumers.
