Unmanned aerial vehicle multi-dimensional recognition system and method

Abstract

The invention discloses an unmanned aerial vehicle multi-dimensional recognition system and method, belongs to the technical field of anti-unmanned aerial vehicle recognition, and aims to solve the problems that the unmanned aerial vehicle cannot be quickly and accurately detected in a long-distance and variable-distance range and an accurate judgment result cannot be given in the prior art. The unmanned aerial vehicle multi-dimensional recognition system comprises an information acquisition unit, a spatial position positioning unit, a control unit and an early warning unit. The information acquisition unit comprises an image acquisition unit, a sound acquisition unit and a radio signal acquisition unit. Unmanned aerial vehicle image information, unmanned aerial vehicle sound information and radio signals in the target area are acquired through the information acquisition unit and transmitted to the control unit. The spatial position positioning unit acquires spatial position information of the unmanned aerial vehicle and transmits the spatial position information to the control unit; and the control unit judges whether the unmanned aerial vehicle is an unmanned aerial vehicle or not according to the information acquired by the information acquisition unit and the spatial position positioning unit and transmits a judgment result to the early warning unit.

Description

technical field [0001] The invention belongs to the technical field of anti-drone identification, and in particular relates to a multi-dimensional identification system and method for an unmanned aerial vehicle. Background technique [0002] In recent years, with the rapid development of the drone industry, the price of drones has become lower and lower. However, due to the lack of a sound management system, the safety issues caused by the "black flight" of drones have also attracted people's attention. In January 2017, Hangzhou Xiaoshan Airport took aerial photography drones to shoot passenger plane incidents; in April 2017, Sichuan Shuangliu Airport continued to have fixed-wing aircraft models interfere with passenger planes, causing hundreds of flights to divert or return, and more than 10,000 passengers were blocked and stranded The economic loss of the airport is tens of millions of yuan. The safety problems caused by drones are various, which have caused great securit...
