Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
A method for monitoring suspicious persons or suspicious behaviors, as shown in fig. 1, the method comprises the following steps:
step S11: the camera monitors and records the image content and the sound content in real time, the camera transmits the image content and the sound content to a monitoring system, and the monitoring system is divided into an image monitoring system and a sound monitoring system;
step S12: the image monitoring system monitors image content and judges whether suspicious persons or suspicious behaviors exist or not, and the sound monitoring system monitors sound content and judges whether suspicious behaviors exist or not;
step S13: when suspicious people or suspicious behaviors are monitored, the camera automatically focuses on the occurrence area of the suspicious people or the suspicious behaviors;
step S14: for suspicious people, the camera tracks the faces of the suspicious people and takes high-definition pictures;
step S15: recording the latest other characteristics of the suspicious personnel;
step S16: the security personnel confirm the suspicious person or suspicious act on site.
As shown in fig. 2, the hardware system for monitoring suspicious persons or suspicious acts is schematically composed of a monitoring module, the monitoring module is composed of a plurality of cameras, the plurality of cameras are automatic focusing cameras, the monitoring system comprises a plurality of servers, a computer, a video recorder, an alarm and a software monitoring control system, the monitoring system is communicated with a public security end database through a private line, the servers comprise a database server, an application program server and a Web server, the video recorder is used for recording and storing the image content and the sound content of the camera, the computer is used for controlling the software monitoring control system, and the software monitoring control system is used for realizing the judgment, analysis, recording, storage or statistical work of suspicious personnel or suspicious behaviors. The monitoring system transmits images recorded by the camera to the display screens in real time through the decoder for real-time monitoring and early warning, when the camera monitors that suspicious people or suspicious behaviors occur, the display screen monitoring the area can automatically amplify and display, and triggers the alarm to give an alarm to prompt whether the suspicious people exist or not or the suspicious behaviors occur. As shown in fig. 6, when the area corresponding to the camera with the number of 24 has the occurrence of the suspicious behavior, the display area corresponding to the camera with the number of 24 is automatically enlarged and displayed, and an alarm is triggered to give an alarm.
As shown in fig. 3, which is a schematic view of the monitoring system for determining suspicious people and suspicious behaviors, the monitoring system monitors and records image content and sound content in real time through a camera, determines whether the monitoring system is a suspicious person or a suspicious behavior, and after the monitoring system determines that the monitoring system is a suspicious person or a suspicious behavior, the camera automatically focuses on an occurrence area of the suspicious person or the suspicious behavior, and simultaneously automatically amplifies a monitoring video of the area on a display screen, and triggers an alarm of the monitoring system to send a prompt sound. And then tracking the face of the suspicious person by the camera, carrying out high-definition photographing, and recording the latest other characteristics of the suspicious person, including the latest face head portrait, the latest clothes and the height of the suspicious person. The monitoring system extracts face photos of suspicious persons, compares the face photos manually again, judges whether the suspicious persons are involved persons or not, contacts police officers at the first time if the suspicious persons are involved persons, confirms the suspicious persons or suspicious behaviors on site by security personnel if the suspicious persons or the suspicious behaviors are not involved persons, confirms that the criminal behaviors occur, hands over the criminal persons to a police station if the suspicious persons or the suspicious behaviors are confirmed, generates misunderstanding if the suspicious persons or the suspicious behaviors do not exist, updates a local population database, and eliminates amplification warning of a display screen.
As shown in fig. 4, a working diagram of the image monitoring system for determining suspicious persons or suspicious behaviors is shown:
a: monitoring face data, comparing the face data with a local population database, and judging as suspicious people when the local database has no person or blacklist people;
b: monitoring face data, comparing the face data with a public security population database, and judging as suspicious people when related to case-related people;
c: after the time that the person stays at the door is monitored to exceed the set time (30 seconds for the moment), and the person does not enter the door, the person is judged to be a suspicious person or a suspicious behavior;
d: after the person wanders back and forth at the doorway and does not enter the doorway, the person is judged as a suspicious person or behavior;
e: when a distress signal graph is monitored, if the SOS is detected, the SOS is judged to be suspicious;
f: and when the camera is damaged or covered without any influence, the suspicious behavior is judged.
As shown in fig. 5, a working diagram of the sound monitoring system for determining suspicious behavior is shown:
a: when strong sound fluctuation is monitored, and decibels exceed a set value (or noisy sound or impact sound and the like), the behavior is judged to be suspicious;
b: when the distress sound is monitored, the sound monitoring system identifies and judges the sound to be suspicious behavior.
The cameras are reasonably arranged, suspicious people or suspicious behaviors can be effectively and timely monitored through real-time monitoring, analysis and early warning of the cameras, and then the occurrence of illegal behaviors can be effectively prevented through manual investigation of security personnel.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
