Problems solved by technology

[0003] In order to reduce repeated alarms, the traditional method adopts an alarm time interval, such as an alarm once per second to reduce repeated alarms, but when the face of the alarm personnel appears in the video scene for too long, the alarm will still be repeated; especially the head When the face is twisted and the shooting angle of the face changes greatly, it is easier to be regarded as two different people and call the police repeatedly, which increases unnecessary workload

Embodiment 1

[0036] see figure 1 , the present embodiment provides a method for avoiding repeated alarms in a human inspection and quarantine system, including the following steps:

[0037] 1) Obtain the infrared video image data and visible light video image data of the human body, and use the infrared thermal imaging temperature measurement method to monitor the feverish personnel in the infrared video image data. When a feverish person is detected, perform step 2), otherwise, continue to execute step 1);

[0038] 2) Use the matching relationship between the infrared image and the visible light image to detect the face image area of ​​the person with fever in the visible light video image, and determine whether the face image area is being tracked;

[0039]21) If the face image area is not tracked, take a screenshot of the face image area, save it, and report to the police, and simultaneously extract the features of the face image area, and use the tracking algorithm to track the alarm ...

Embodiment 2

[0052] This embodiment provides a device for avoiding repeated alarms in a human inspection and quarantine system, including an infrared video image data acquisition module, a visible light video image data acquisition module, an infrared thermal imaging temperature measurement module, a tracking module, a matching module, and a human face image acquisition module. Area screenshot module, alarm module,

[0053] The infrared video image data acquisition module is used to acquire infrared video image data of the human body;

[0054] The visible light video image data acquisition module is used to acquire visible light video image data of the human body;

[0055] The infrared thermal imaging temperature measurement module is used to monitor the fever personnel in the infrared video image data;

[0056] The tracking module is used to extract the features of the face image area of ​​the fever personnel, and track the face image area of ​​the fever personnel;

[0057] The matching...

Embodiment 3

[0062] This embodiment provides a device for avoiding repeated alarms in a human inspection and quarantine system, including a memory for storing programs;

[0063] And a processor, the processor is configured to implement the steps of the above-mentioned method for avoiding repeated alarms in a human inspection and quarantine system when executing the program.

[0064] In order to avoid repeated alarms during temperature measurement in the infrared human body inspection and quarantine system, the present invention adopts the method of tracking the faces of the alarm personnel to judge whether there are repeated alarms, and judges the image clarity of the alarm personnel, and saves the clearest screenshots.

Abstract

The invention discloses a method, device and equipment for avoiding repeated alarms in a human body inspection and quarantine system. The method for avoiding repeated alarms in the human body inspection and quarantine system comprises the following steps that infrared video image data and visible light video image data of a human body are acquired, and heating personnel in the infrared video imagedata are measured by using an infrared thermal imaging temperature measurement method; when the heating personnel are monitored, a face image area of the heating personnel in a visible light video image is detected by using the matching relationship between an infrared image and the visible light image, and whether the face image area is tracked or not is judged; if the face image area is not tracked, screenshots of the face image area are saved, an alarm is given, and the face image area is tracked at the same time; and if the face image area is tracked, no alarm is given. The human body inspection and quarantine system is prevented from repeatedly alarming the same alarm personnel.

Description

technical field [0001] The invention relates to the technical field of intelligent detection applied in the field of infrared thermal imaging temperature measurement, in particular to a method, device and equipment for avoiding repeated alarms in a human body inspection and quarantine system. Background technique [0002] The infrared human body inspection and quarantine system is applied to entry-exit ports. People are walking, but their facial postures change in various ways, and the angles of bowing their heads, raising their heads, and turning their heads are different. If there are multiple occurrences in the field of view of the dual-light imaging module of the quarantine system from far to near, multiple alarms will be generated. The existing technology is to reduce repeated alarms through time control methods, such as one alarm every 1 second; if a feverish person stays in the scene for too long, the alarm will still be repeated; and if there is a feverish person dur...
