Guangzhou Baiyun: Innovative "drone +AI" low-altitude inspection, so that urban governance "fly" on the cloud

Drones automatically cruise to supervise illegal construction, equipped with infrared cameras to capture the theft of construction waste, AI to identify ground sanitation waste and road occupation operations... In recent years, the Urban Management and comprehensive law Enforcement Bureau of Baiyun District of Guangzhou has continued to expand the application scenario of low-altitude UAV inspection, built four UAV automatic airports, built a UAV flight control platform, developed Baiyun smart urban management, and built a low-altitude intelligent remote sensing network, which has initially formed a "drone +AI" low-altitude inspection supervision mode, allowing urban governance to "fly" on the cloud.

One-click inspection, intelligent flight, AI algorithm accuracy rate reached the forefront of the country

In the Baiyun District urban management and monitoring command center, after the staff click the mouse and issue the cruise task instruction, a drone takes off from the drone airport located on the roof of the Baiyun Traffic Building, automatically adjusts the flight attitude and the Angle of the head according to the preset route, and automatically sends back the pictures and videos captured by the cruise. Through AI intelligent identification, comparison analysis and review, the background will push the suspected illegal construction clues to form work orders to the territorial town street for verification. The whole process of monitoring illegal construction of drones is very smooth.

"Now we only need to pre-set the cruise route on the UAV flight control platform to achieve 'one-click inspection' and closed-loop management of work order disposal." It can also design routes according to different regions and work needs, select parameters such as take-off location, altitude and speed, and view the flight status, position and live video of the UAV in real time." The relevant person in charge of the Baiyun City management violation supervision Department said that a drone airport can monitor about 15 square kilometers a day, and the inspection efficiency is more than 2 times that of the traditional manual inspection mode, and the UAV aerial photography makes the illegal construction of the roof with strong hiding nowhere to hide, and can be found early, intervene early, and deal with quickly, so as to curb the new illegal construction from the source.

In the recent night of special law enforcement operations, law enforcement officers used drones with infrared imaging technology to patrol and found that there was a suspected illegal act of hiring a "pheasant truck" to transport construction waste at a construction site in Shii Street. Law enforcement officers immediately took photos and took evidence and rushed to the scene for verification, and quickly handed over the street law enforcement office to investigate and punish according to law. Pilot Xiao Yang said, "In the past, it took several hours to drive to inspect the site at night, but now it can achieve full coverage in about half an hour by operating the drone." It is reported that since July 2023, Baiyun District has used drones to patrol the construction site, and eight illegal acts have been filed and punished.

It is worth mentioning that Baiyun urban management has developed a number of thematic AI algorithms such as illegal construction and sanitation waste, and its accuracy rate has reached the forefront of the country, according to the calculation of Guangzhou Urban Planning Survey and Design Institute. In China, we took the lead in using "drone airport +AI" to realize the identification of sanitation waste, and used multi-rotor drones to intelligently capture city and environmental health problems at a height of more than 100 meters. Relying on the integration and enhanced positioning technology of the Big Diouxing, we accurately located the problem location and pushed the work order to the territorial section for rectification. Realize the closed-loop management of "intelligent aviation - AI automatic discovery - clue push - disposal supervision", make the UAV become the "air urban management", greatly extend the height and breadth of urban management, and improve the quality and efficiency of urban management. At present, Baiyun urban management is piloting the function of drone inspection of construction waste, marking more than 600 samples in just over a week, and the identification accuracy rate is 81%.

Scene application is an important embodiment of low-altitude economy to create social value. Baiyun urban management continues to expand low-altitude application scenarios, and low-altitude UAV inspection has now expanded to many law enforcement and supervision matters such as illegal construction, disorderly stacking of construction waste, occupation of roads, sanitation waste, night construction of construction sites, and theft of mud, effectively improving the level of urban management intelligence and refinement.

Build a low-altitude intelligent remote sensing network to ensure that drones "can fly, manage and fly well"
The safe and orderly low-altitude flight of UAVs depends on the support of low-altitude economic important infrastructure such as low-altitude intelligent remote sensing network, including UAV airport, thematic AI algorithm, and UAV flight control platform.

At present, Baiyun Urban management has built four UAV automatic airports in Taihe Town and Zhongluotan Town, with automatic release, automatic storage, automatic charging and other functions, 24 hours at any time. Synchronous development of "UAV flight control general center", has launched command and dispatch, flight control, route planning, data management, flight record, route management and other functions, to achieve remote real-time control of UAV, UAV take-off and landing, flight trajectory setting, line task planning, timing task execution, etc., can be "one-click operation" on the PC end. As long as the navigation information such as track, waypoint, Angle and inspection target is set on the system, the UAV can automatically take aerial images according to the established route. After the inspection is completed, it will automatically return, land accurately, and download data automatically. At the same time, the layout and construction of "4 fixed-wing +25 multi-rotor" UAV groups achieve full coverage of the non-no-fly zone of Baiyun, meet the needs of daily high-frequency multi-scene dynamic inspection, gradually improve the all-round, three-dimensional and intelligent low-altitude intelligent remote sensing network, and build important low-altitude economic infrastructure.

According to reports, Baiyun urban management is introducing China Mobile 5G-A synaesthesia integration technology to explore low-altitude flight detection and control methods, so that drones can "fly, manage and fly well." Taking Sanyuanli and other streets as the pilot, Baiyun Urban Management develops the three-dimensional "one map" of Baiyun smart urban management, which gathers data such as images, electronic maps, building white models, urban components, and personnel tracks, and realizes functions such as the above picture of urban components, real-time monitoring of personnel tracks, video camera viewing, and thematic analysis of building businesses. The person in charge of the Baiyun District urban management monitoring command center said, "The development and application of three-dimensional map has created a three-dimensional low-altitude flight data platform for the real scene, laying a solid foundation for the accurate and efficient setting of UAV routes."

In addition, in order to facilitate drone law enforcement, Baiyun urban management selected personnel to participate in drone operation training, and a total of 18 people obtained the "Civil Unmanned Aircraft Operator License".

"The layout and construction of UAV groups can not only serve the urban management of Baiyun District, but also can be reused in the whole district, enabling emergency rescue, forest fire prevention and other fields, and synsensory integration technology and real three-dimensional low-altitude flight data platform also provide reliable infrastructure support for the development of low-altitude economy." The main person in charge of Baiyun urban management said that the next step will be the new development positioning of Baiyun District's "international hub gateway and landscape smart urban area", seize the strategic opportunities of low-altitude economic development, constantly expand the scene of UAV law enforcement and supervision, empower smart city management with low-altitude economy, form a reusable low-altitude remote sensing intelligent monitoring network in the region, and provide efficient and intelligent services to the public. Build a pattern of "open space in one", achieve all-round, full-time, no-dead corner supervision, insert "wings of wisdom" for urban governance, and contribute to the urban management force to promote the practice of Chinese-style modern Baiyun.
