Unmanned aerial vehicle ground crowd monitoring system and monitoring method

Abstract

The invention discloses an unmanned aerial vehicle ground crowd monitoring system. The system comprises a ground information platform and at least one monitoring unmanned aerial vehicle; the monitoring unmanned aerial vehicle comprises a ground shooting camera, a processor, a wireless transmission mechanism and an illuminance sensor; the processor is bidirectionally connected with the camera and the wireless transmission mechanism; the wireless transmission mechanism wirelessly communicates with the ground information platform; and the illuminance sensor is bidirectionally connected with the camera or the processor. A monitoring method comprises the steps of identifying crowd density through image transparency; coloring crowd images with different densities; and finally calculating out crowd distribution change data. The system has the beneficial effects that the requirements on hardware of the unmanned aerial vehicle are low, and information of crowd number, density, movement and thelike is visually obtained; and the crowd density is colored, so that a manager can visually see a crowd distribution condition, personnel deployment of safety protection is accurately scheduled, the image analysis time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crowd monitoring, in particular to an unmanned aerial vehicle-to-ground crowd monitoring system and a monitoring method. Background technique [0002] Crowd gathering is a legal right of citizens, but often due to the large number of people gathering and the lack of personnel management, frequent accidents, stampede incidents, robbery and other criminal incidents emerge in endlessly, causing heavy losses to both the gathering personnel and management personnel. [0003] Nowadays, the monitoring of gathering crowds is usually to deploy more guards and security personnel to carry out decentralized supervision, so that the distribution of the crowd can be grasped in real time to a certain extent, but in some particularly densely populated areas, security personnel cannot even squeeze in, and these Blind spots in monitoring are the most dangerous areas where accidents are most likely to occur; the emergence o...

Problems solved by technology

[0002] Crowd gathering is a legal right of citizens, but often due to too many people in the gathering and lack of personnel management, frequent accidents, stampede incidents, robbery and other criminal incidents emerge in endlessly, causing heavy losses to both the gathering personnel and management personnel

[0003] Nowadays, the monitoring of gathering crowds is usually to deploy more guards and security personnel to carry out decentralized supervision, so that the distribution of the crowd can be grasped in real time to a certain extent, but in some particularly densely populated areas, security personnel cannot even squeeze in, and these Blind spots in monitoring are the most dangerous areas where accidents are most likely to occur; the emergence of drones provides convenience for dense crowd monitoring, but the use of drones in existing technologies is limited to video shooting and transmission to the ground for monitoring and making by managers. Response, which requires managers to focus on the surveillance video at any time. Occasionally, a distraction may lead to untimely security scheduling, which may cause major accidents

[0004] Disadvantages of the existing technology: lack of a system that automatically monitors the crowd, recognizes and sends an alarm in time according to the crowd situation, and reminds the management to dispatch security forces and increase or decrease security personnel
