Embodiment Construction
[0026] In order to make up for the gaps in existing equipment, a set of unmanned aerial vehicle platforms that combine the characteristics of small and light, easy to fly / recover, and work heights suitable for urban environments are proposed to automatically track the location of military police / security personnel, and at the same time provide surrounding information. Situation detection system. The monitoring system provided by the invention can automatically follow the movement of security personnel, and can also meet different task requirements by adding different modules. For this reason, the technical solution adopted by the present invention is a tracking and positioning method and system based on optical coding, including hardware equipment parts, software parts, working status and tracking methods, wherein:
[0027] Hardware equipment part: The hardware equipment part includes tracking platform, navigation platform and information terminal.
[0028] The tracking platf...

Description
technical field [0001] The invention relates to an unmanned aerial vehicle and its application, and a solution for monitoring the surrounding situation when military police or security personnel are patrolling in urban areas. Specifically, it involves tracking, positioning and detection systems for drones. Background technique [0002] When military police\security personnel maintain daily law and order in urban areas or conduct armed patrols in high-risk areas, they need to accurately and timely grasp the surrounding situation. In particular, when patrolling in the block, the patrolling personnel are the center, and the surrounding horizontal distance is 30-50m and the vertical height is 30-50m. In the space of 3-20m, it is easy to become a monitoring blind spot. At the same time, in large-scale public places (such as pedestrian streets, squares, etc.) with a huge flow of people during holidays, patrol personnel also need to keep abreast of the surrounding conditions.
