| With the increase in the number of monitoring equipment,video surveillance has gradually become an important tool for maintaining public order and the rule of law,and it has also become an important support for coordinating traffic resources in smart cities.Through the existing video surveillance and positioning,more and more important location and behavior information of pedestrians and driving can be grasped,but the amount of information currently obtained still cannot keep up with the huge information demand in the future era of Internet of Everything.For example,on long viaducts,remote villages,and vast seas,it is impossible to densely populate camera devices;for example,in cities in high-rise forests,fixed cameras will be blocked,leaving many dead spots for monitoring.Existing domestic UAV manufacturers have gradually mastered core technologies such as remote communication,GPS positioning and flight control,and have gradually reduced their costs to a level that can be widely used by civilians.UAVs have high-altitude wide viewing angles and high spatial freedom,and can be used as an important part of tracking and surveillance systems.This paper combines UAV technology to design and implement a UAV Target Tracking Information Display System(UTTIDS).The display function of the system uses the B/S architecture and is displayed on the Web side.The server and It is composed of drones,using the method of multi-drone scheduling and tracking to monitor the target,using a centralized server for flight control and scheduling of each drone,collecting the information of the surveillance drone,and using the two-dimensional electronics on the Web side The map displays the monitoring information,the location information of the drone,and the working status to the user.This article first introduces the background and research significance of UAV tracking and monitoring,and introduces UAV-related technologies such as flight control,communication,electronic maps and application platforms.Then analyzed the functions that UTTIDS needs to implement in the display,scheduling,flight control,etc.,and designed the scheduling algorithm according to the demand analysis,designed the structure of UTTIDS,the architecture of the server and the UAV client,and used Python,Html and Android has done system development and realized the functions of UTTIDS system.After the system was implemented,the effectiveness of the flight control function was tested on the spot,the efficiency of the scheduling algorithm was tested using the simulated multi-UAV client communication,and the real-time viewing and historical query functions of UTTIDS were tested,showing that UTTIDS is on the Android platform and The methods and effects implemented on DJI equipment,and the test results show that the use of trajectory prediction algorithms can reduce the loss rate of target tracking.Finally,the work of this article is summarized,and the prospects of UAV surveillance are prospected. |
