Method for stabilizing screening result of infrared human body surface temperature rapid screening instrument

Abstract

The invention relates to the field of video processing, and particularly relates to a processing method of a video file with temperature information. According to the invention, when a temperature detection early warning system records an infrared thermal imaging picture, the image picture, all full-screen temperature data and temperature measurement rule information in the recording time period are synchronously stored. When the infrared video file is opened by off-line temperature analysis software, whether full-screen temperature data and a temperature measurement area exist or not is determined, and the infrared video file is opened; when the infrared video file is played, the full-screen temperature data and the current data of the temperature measurement rule are positioned through the current playing time point, and the recorded full-screen temperature data is analyzed in real time to calculate the current temperature result of the temperature measurement rule and display the current temperature result on a played-back video picture. The invention further relates to a remote transmission process of the data, i.e., the total data is transmitted to a central server to be processed by a supervisor, the component data is transmitted to a user server to be checked by a specified user, and the accuracy of the data is determined through the interaction of the central server andthe user server; and by setting a storage area and storage data in the user server, the data security is ensured, and the data tampering is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of image and data processing, and relates to a method for stabilizing the screening results of an infrared human body surface temperature rapid screening instrument. Background technique [0002] The infrared human body surface temperature rapid screening instrument is mainly used in fast passages with a large flow of people, and is used to screen places that carry viruses and cause fever in the human body. Screening the body temperature of the human body through infrared temperature measurement is an important technical prevention measure for epidemic prevention. [0003] The research on the practical application of the infrared human body screening instrument shows that when using the infrared human body surface temperature rapid screening instrument to measure the body surface temperature of the exposed skin on the head and face of the human body for screening, the temperature of the exposed skin on the h...

[0003] The research on the practical application of the infrared human body screening instrument shows that when using the infrared human body surface temperature rapid screening instrument to measure the body surface temperature of the exposed skin on the head and face of the human body for screening, the temperature of the exposed skin on the head and face of the human body is affected by many factors. As a result, the measurement results will fluctuate significantly. In the high frame rate image video, it is shown that the marked human body temperature fluctuates continuously, which affects the correct reading of the human body temperature value by the screening staff.

In addition, the infrared human body screening instruments currently on the market can mark the face recognition frame and body temperature value of the human body in the screening area, and when one or several human body targets in the screening area exceed the preset body temperature alarm threshold ( Such as 37.3 ℃), the alarm sound will be issued, but this alarm method judged only according to the alarm threshold will cause the alarm sound to be generated continuously, and the alarm will not be released until all the fever targets leave the screening range

This not only affects the screening results, but also the continuous alarm sound becomes noise pollution, which also has a very bad impact on the health of the screening staff

[0004] Moreover, when the current technology finds an abnormality, it is necessary to manually notify the abnormal personnel; when the number of people is large, it is easy to cause the loss of personnel, resulting in the inability to accurately track and locate

When processing data, it is usually processed locally and then reported directly to the server cluster in the data center in a periodic or real-time manner. At this time, the load of each server in the server cluster and the status of the access point are not considered. The stability and reliability of data transmission cannot be guaranteed, which may easily lead to data loss
