With their unique aerial perspective and high maneuverability, they play a huge role in traffic monitoring, accident investigation, and capturing illegal behavior.

[0003] In security deployment, drones can be equipped with warning devices such as cones to achieve fast and accurate placement of cones. Compared with traditional manual placement methods, drones have the following advantages: Efficiency: Drones can quickly fly to designated locations and achieve rapid placement of cones, greatly improving work efficiency.
