Rapid large-range crowd gathering condition monitoring method based on vehicle-mounted unmanned aerial vehicle

Abstract

The invention provides a rapid large-range crowd gathering condition monitoring method based on a vehicle-mounted unmanned aerial vehicle, and aims at monitoring crowd gathering in community open-airpublic places under epidemic prevention and control situations. The method comprises the steps that a sensor is used for collecting moving object motion data, a to-be-monitored area is divided into aplurality of task subareas where gathering possibly occurs, and the unmanned aerial vehicle is carried by a vehicle to reach the subareas; the infrared temperature measurement unmanned aerial vehicleis launched to scan the subareas, and suspected gathering places are preliminarily marked; a flight path of the unmanned aerial vehicle is planned and detected to perform image data acquisition on a suspected aggregation point; an efficient distribution scheme is calculated for the collected image data processing tasks, pattern recognition is carried out in combination with the calculation capabilities of the unmanned aerial vehicle, the vehicle and the dispatching center, and to-be-dispelled places are screened out; and finally, the unmanned aerial vehicle with camera shooting and broadcasting equipment is manually controlled to arrive at the to-be-dispelled place to observe and dispel the crowd. Compared with an existing monitoring method, the method has the advantages that the monitoring range is expanded, the workload of prevention and control personnel is reduced, and the possibility of monitoring blind spots is reduced.

Description

technical field [0001] The invention relates to the fields of epidemic prevention and control, UAV detection and scheduling, edge computing, etc., and specifically relates to a method for monitoring large-scale crowd gatherings based on vehicle-mounted UAVs. Background technique [0002] In the prevention and control of the new crown epidemic, community (and rural) detection and control of crowd gatherings in public places has become an important and extremely cumbersome task. In order to reduce the burden on prevention and control staff, many communities (and rural areas) have adopted drone technology to assist in this work. The existing UAV crowd gathering method is to use artificial remote control UAV patrol. The characteristic of the current method is that each UAV must be remotely controlled by at least one person, and the aggregation situation can be manually identified through the camera equipment carried by the UAV. The monitoring range of this method is affected b...

AI Technical Summary

Problems solved by technology

The monitoring range of this method is affected by the endurance of the drone, and the monitoring range is very limited

Moreover, the operation of drones is difficult, and the relevant staff need to spend energy and time receiving professional skills training, the workload is heavy, and manual monitoring is prone to omissions
