Embodiment 1

[0049] figure 1 The implementation process of the edge computing-based safety helmet wearing detection and identification method and the alarm system provided by the first embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0050] In step S1001, a video image is acquired;

[0051] In the embodiment of the present invention, a video image may be acquired through a camera, a camera recorder, or a video recording storage server, and further preferably, a real-time video image may be acquired.

[0052] In step S1002, it is judged whether the person in the video image is wearing a hat, if yes, go to step S1003, and if so, go to step S1004;

[0053] In the embodiment of the present invention, preferably, it is determined whether the person in the video image is wearing a hat, and if so, it is determined whether the hat is a safety helmet, and ...

Embodiment 2

[0061] figure 2 The implementation process of the edge computing-based safety helmet wearing detection and identification method and the alarm system provided by the second embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0062] In step S2001, a video image is obtained;

[0063] In the embodiment of the present invention, a video image can be acquired through a camera, a camera recorder, or a video recording storage server, and further preferably, a real-time video image can be acquired.

[0064] In step S2002, humanoid features are obtained from the video image;

[0065] In the embodiment of the present invention, a humanoid feature model is preset, and a humanoid feature matching the humanoid feature model is acquired from the video image according to the preset humanoid feature model.

[0066] In step S2003, the head of the perso...

Embodiment 3

[0075] image 3 The implementation process of the edge computing-based safety helmet wearing detection and identification method and the alarm system provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0076] In step S3001, the camera acquires the video image of the captured image area in real time;

[0077] In step S3002, the video image is sent to the nearest edge computing node;

[0078] In the embodiment of the present invention, using the server of the edge computing node to perform data processing operations nearby can reduce the calculation pressure of the central server, and only send the safety protection information, danger protection information, and danger alarm information after the judgment and processing to the central server, It greatly saves broadband resources, and at the same time, it can improve ...

Abstract

The invention is applicable to the technical field of safety helmet wearing detection and identification, and provides a safety helmet wearing detection and identification method based on edge calculation and an alarm system, and the method comprises the steps: enabling a camera to obtain a video image of a collected image region in real time, transmitting the video image to a nearest edge calculation node, and enabling the edge calculation node to judge whether a person in the video image wears a helmet or not; performing consistent comparison according to the preset characteristics of the safety helmet and the characteristics of the hat, triggering safety protection information of wearing the safety helmet if the consistent comparison succeeds, and triggering danger protection information of not wearing the safety helmet if the consistent comparison fails; the edge computing nodes also send the danger alarm information, the safety protection information and the danger protection information to the central server; the central server sends out a corresponding alarm prompt according to the received danger alarm information, safety protection information and danger protection information; therefore, the safety helmet wearing detection precision is improved, the detection time is shortened, and the user experience is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of safety helmet wearing detection and identification, and in particular relates to a safety helmet wearing detection and identification method and an alarm system based on edge computing. Background technique [0002] Being hit by falling objects is a potential hazard in all engineering sectors, resulting in many work-related injuries and fatalities; wearing hard hats can effectively reduce injuries caused by falling objects; therefore, in the construction, manufacturing, oilfield and chemical industries It is mandatory for the construction sites of factories and other enterprises that operators must wear safety helmets, but some engineering personnel do not abide by the regulations of wearing safety helmets; [0003] The use of image recognition technology to detect whether workers on the construction site wear safety helmets and timely detection of workers who do not wear safety helmets in accordance with...
