Embodiment 1

[0046] Such as figure 1 As shown, a campus security monitoring system based on the Internet of Things includes multiple cameras installed in the campus (the camera adopts Dahua 8 million DH-SDT-5A1804WA-C8P network high-definition infrared waterproof wide dynamic monitoring camera), and is installed in the security guard The monitoring terminal in the room (using Lenovo all-in-one desktop computer) and the mobile phone terminal of the school personnel (using Huawei P40 mobile phone); also includes the server (the model uses Dell EMC PowerEdgeT30 micro-tower server), the server includes database, input module, processing module and output module; where:

[0047] The database is used to store the pre-stored face images of personnel in the school and the installation location information of each camera on the campus; the pre-stored face images are bound with corresponding mobile phone numbers; in this embodiment, for ease of illustration, three cameras (one No. camera, No. 2 cam...

Embodiment 2

[0063] Compared with Embodiment 1, the only difference is that it also includes an image acquisition module arranged on a slippery road section for real-time acquisition of video images; an input module is also used for acquiring video images; a processing module is also used for using frame The inter-difference method processes the video image into an image sequence. If a moving target appears in each frame of the image sequence, the moving target is positioned and the human body outline frame is extracted; an analysis module is also included to establish a two-dimensional model, and each frame The human body outline frame extracted from the image sequence is input into the two-dimensional model, and the angle parameters between each human body outline frame and the horizontal axis are calculated. If the angle parameter is less than the preset angle threshold, it is judged that a fall behavior has occurred, and a fall prompt message is generated. ; The output module is also us...

Embodiment 3

[0070] Compared with Embodiment 2, the only difference is that the database is also used to store several falling images in advance; it also includes a judging module, which is used to judge whether there is a falling target in each frame image sequence according to the prestored falling images, If the image sequence has a falling target, record the time stamp of the image sequence to generate the first time information; and extract the image sequence in which the human body outline frame of the falling target is standing in the previous frame image, generate a reference image, and record the same The time stamp of the image sequence generates second time information; the processing module is also used to calculate the absolute value of the difference between the first time information and the second time information, if the absolute value is greater than the second preset threshold, it is judged as normal sitting On the contrary, it is determined as a falling state; in other e...

Abstract

The invention relates to the technical field of campus monitoring systems, and particularly relates to a campus safety monitoring system and method based on the Internet of Things. The system comprises a plurality of cameras disposed in a campus, a monitoring terminal disposed in a security room, and a campus personnel cellphone terminal, and further comprises a server, wherein the server comprises a database, an input module, a processing module and an output module; the database is used for storing pre-stored face images of people in the campus and installation position information of each camera in the campus; the pre-stored face image is bound with a corresponding mobile phone number; the input module is used for acquiring current images acquired by the plurality of cameras in the campus; and the processing module is used for extracting all to-be-detected face images in the current image according to an image processing algorithm, processing the to-be-detected face images accordingto a face recognition algorithm and comparing the to-be-detected face images with the pre-stored face images in the database. By adopting the scheme, the problem of weak safety can be solved.

Description

technical field [0001] The invention relates to the technical field of campus monitoring systems, in particular to a campus security monitoring system and method based on the Internet of Things. Background technique [0002] In recent years, the rapid development of computer information management has driven the progress of various social services, and its combination with information technology has made the campus security remote real-time monitoring system a research hotspot in the information age. In the traditional campus security management mode, it is necessary to manually realize the inspection, recording and processing of the campus, and there are problems such as low work efficiency and poor security; however, the emergence of the campus security remote real-time monitoring system solves this problem. All-round, full HD video three-dimensional management and monitoring of the venue. In addition, it can also remotely control the camera and PTZ, set various alarms an...
