Incidents of "black flying" drones injuring people and objects have occurred from time to time. In the second half of 2016 alone, there were hundreds of accidents, such as forced suspension of flights, crashes from large-scale events, etc. Recently, there have been flight accidents in Canada and Ningbo Hefei high-speed injuries. It can be seen that Hefei drones hide a large number of potential safety hazards. Faced with the gap in the supervision of black flying drones, only strong countermeasures can be taken to ensure air safety.
