Crowd gathering early warning unmanned aerial vehicle

Abstract

The invention relates to early warning equipment for vehicles, in particular to a crowd gathering early warning unmanned aerial vehicle. A camera collects samples, and pre-judgment of the crowd intensity and warning are completed through cooperation of a target calibration module, a target track pre-judgment module, a crowd gathering degree prediction module and an early warning judgment module. According to the unmanned aerial vehicle, the camera can be utilized to collect video information; firstly, the video information is compared with a standard characteristic database to determine an accurate target group; then the video information with multiple-frame numbers is processed; the tracks of targets are pre-judged; the track line set of the multiple targets serves as an object; a target area is delimited; pre-judgment of the crowd gathering degree can be achieved as long as the condition of tracks in the target area is obtained; and a pre-judgment value is compared with the crowd intensity standard, and if the pre-judgment value exceeds the standard, early warning is conducted. Thereof, the unmanned aerial vehicle can monitor the situation of the crowd density, make early warning judgment and process the information in time, so that information process delaying is avoided, and prevention is well conducted.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a crowd gathering early warning unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote control with a parachute or a...

Problems solved by technology

[0003] UAVs only provide the function of eyes in the process of military or civilian use, or use the built-in equipment to do some actions, the degree of intelligence is not high, and the information cannot be automatically processed and screened, so the final information must be transmitted to the terminal for further processing. processing, so the speed of information processing is not fast, and the drones currently used for monitoring only have their own cameras, and cannot do further information processing, resulting in delays in information processing
