Unmanned aerial vehicle invasion detection and identification system based on visual sense and method thereof

Abstract

The invention discloses an unmanned aerial vehicle invasion detection and identification system based on a visual sense and a method thereof. The system comprises a plurality of cameras, a target detection module and a target identification module. The target identification module comprises a movement track determination device, an optical flow characteristic determination device, a zooming controller and a characteristic matcher. The cameras are deployed around a monitoring area. After the target detection module detects moving targets, through track determination and optical flow characteristic determination, preliminary screening is performed on the targets and parts of non-unmanned-aerial vehicle targets are eliminated. The cameras are controlled to zoom so as to acquire a sharp image. Through a scale-invariant characteristic transform matching algorithm, matching identification is performed on the targets. In the invention, an optical detection device is adopted, a visual sense detection and identification algorithm is used, unmanned aerial vehicle invasion in a monitoring range can be rapidly and accurately detected and identified, the system and the method are suitable for places which have an anti-unmanned-aerial-vehicle demand, such as an airport, a prison and the like, and detection and identification capabilities of unmanned aerial vehicle invasion are increased.

Description

technical field [0001] The invention belongs to the field of anti-drone technology and the field of visual detection and recognition technology, and in particular relates to a vision-based UAV intrusion detection and recognition system and method. Background technique [0002] In recent years, through the continuous efforts of DJI, Parrot, 3DRobotics and other companies, the price of consumer drones with powerful functions has been continuously reduced, and the ease of operation has been continuously improved. Drones are rapidly transferring from cutting-edge military equipment to the mass market. , and become a toy in the hands of ordinary people. However, with the rapid growth of the consumer drone market, new drones with more and more advanced functions continue to emerge. Drones are widely used in various industries, bringing a lot of convenience, but also Security and privacy concerns. Accidents related to drones are on the rise, and crimes using drones are no longer ...
