The singular forms "a", "an" and "the" may include the plural forms as well.
Referring first to fig. 1, the temperature monitoring method of the present invention mainly includes the following steps:
and S1, acquiring an infrared image and a visible light image of each object to be monitored. Images of passing target objects may be acquired simultaneously with a thermal imaging camera and a visible light camera.
And S2, identifying the visible light image through the target identification technology and determining the detection area. If the object to be monitored is a human body, the target recognition technology can be a face recognition technology, and the face recognition model is used for extracting and judging the features of the image. After the face region is identified, any region can be located and used as the detection region. For example, the forehead portion of a human face may be used as the detection region.
And S3, judging the temperature corresponding to the detection area according to the infrared image, and alarming if the temperature exceeds a first preset value. After the detection area is determined, a thermal imaging area map corresponding to the pixel position can be found in the infrared image, and the temperature corresponding to the thermal imaging area map is determined to be the temperature of the forehead. If the temperature of the forehead exceeds a first preset value, the temperature of the human body is considered to be excessive, and an alarm is given. The alarm mode can be a combination mode of images and sounds.
Through the mode of image processing, can avoid closely gathering the temperature, solve the problem that inefficiency and easy gathering are infected, simultaneously, can utilize the detection area in the target identification technique discernment visible light image, the pertinence detects, can reduce the probability of false detection, improves the temperature detection rate of accuracy, avoids leading to the inaccurate temperature of temperature because long-distance measuring.
In the above S3, when it is determined that the temperature corresponding to the detection area exceeds the first preset value, it is further determined whether the object to be monitored in the visible light image is the same as the object to be monitored corresponding to the last alarm, and whether the last alarm distance is within the preset time range of the time period of this determination; if the objects to be monitored in the two times are the same within the preset time range, no alarm is given.
If the temperature of one human body exceeds the standard after being monitored, the first alarm is carried out, and the same human body is always in the monitoring area within a preset time range such as 10s or passes through the monitoring area repeatedly, multiple alarms are not carried out, only one alarm is carried out, and repeated detection and repeated alarm within a short time can be effectively avoided (repeated detection cannot be carried out within ten seconds).
For the temperature monitoring method, the following operation may also be performed, and if the temperature of the detection area corresponding to one infrared image in the preset time range of the same object to be monitored is greater than the average value of the temperatures of the detection areas corresponding to other infrared images, or is greater than a second preset value, no alarm is performed, where the second preset value is greater than the first preset value.
If the target human body is in the detection area within 10s, the temperature detected in the first 5s is normal, but the temperature identified by one image far exceeds the preset value, or the average temperature value in the first 5s, the temperature far exceeding the first preset value is considered to be abnormal, and no alarm is given. Therefore, a time sequence filtering strategy is designed for the problem of sudden and violent temperature of the infrared camera. If the temperature of only one image is extremely violent, the repeated human faces detected by the human face recognition algorithm are filtered. If the temperature of the multiple images is abnormally increased, the high temperature of the human body is judged, and early warning is triggered.
For the temperature monitoring method, the following operations can be executed, the visible light image is identified through a target identification technology, whether the identification result contains a preset object or not is judged, and if the identification result does not contain the preset object, an alarm is given; and counting the average temperature of the site in each time period and/or the average temperature of the detected object to be monitored, and dynamically adjusting the first preset value according to the average temperature of the site and/or the average temperature of the object to be monitored. And aiming at the scene with large day and night temperature difference, a dynamic temperature adjustment strategy is designed. In addition, it will be understood by those skilled in the art that the temperature is measured as a reference temperature on the average of the day and night. And the temperature measured by all the personnel is integrally and automatically adjusted based on the reference temperature.
In this embodiment, whether the target meets the preset condition can be determined through the recognition algorithm, for example, a mask of a preset object is recognized, and if no mask of the preset object is found, an alarm is given.
In a possible implementation manner, a video fusion technology is adopted to superpose and display the target frames of one or more objects to be monitored and the temperature results corresponding to the detection areas in the same image, and the temperature results are displayed. In order to quickly locate the person with abnormal body temperature, all the face frames and the corresponding temperatures can be simultaneously displayed in an overlapping mode. And the multi-person same-frame detection is supported, and the measured temperature of each person is displayed in real time. Compared with the traditional infrared temperature measurement camera, the temperature measurement efficiency can be greatly improved. The method is suitable for the scene with dense people stream.
Referring to fig. 2, a flow chart of the detailed steps of a temperature monitoring method according to an embodiment of the invention is shown. As shown in fig. 2, the method employs two video streams. Step 201, a visible light video stream collected by a visible light camera and a temperature video stream collected by a thermal imaging camera. Step 202, decoding and frame extracting are respectively carried out on the two video streams. And 203, performing face recognition and mask recognition on the extracted video frames for the visible light videos, determining the temperature corresponding to the forehead area of the face for the temperature videos, and performing infrared temperature taking compensation. And step 204, displaying the forehead temperature and the face frame on a video picture in real time by adopting a video fusion technology. And step 206, after face duplicate removal is carried out on the temperature video stream, if the temperature is abnormal, an alarm is given. The mask is optimized aiming at the current common mask wearing scene, hot food, hot drinks, electric appliances and other hot spot false alarms are effectively filtered, and meanwhile, the interference generated by repeated detection and repeated alarm can be effectively filtered. Those skilled in the art will appreciate that two videos may be processed simultaneously and synchronously, or with a time difference.

And according to the body temperature threshold set by the regional deployment and control task, alarming the personnel exceeding the body temperature threshold. In addition, the face duplicate removal technology can also effectively avoid repeated detection and repeated alarm in a short time, help the staff on duty to get rid of unnecessary interference, and accurate quick location is suspected to the personnel that generate heat.
The alarm without wearing the mask takes a snapshot of the face image through a face recognition technology, and identifies whether the mask is worn or not through a face attribute model, so that the alarm is given.
In addition, the visible light real-time video, the infrared light real-time video and the name of the display equipment can be displayed simultaneously. The real-time video is based on a video fusion technology, and the face frame, the forehead body temperature and the temperature measurement sight are displayed on the video in real time. The temperature exceeding the alarm threshold value is displayed in red highlight, and the temperature not exceeding the alarm threshold value is displayed in green. In addition, the number of passing persons and the number of alarming times in one day can be counted, and the number of passing persons is not the number of passing persons according to the counting rule considering that the body temperatures of the same person passing the temperature measuring point at the two times in one day are possibly different.
