It should be noted that the current time is a time when M human body forehead temperature values have been detected, or any time after M human body forehead temperature values have been detected.
Step S102, acquiring standard forehead temperature values according to M forehead temperature values detected before the current forehead temperature value is detected; wherein M is more than or equal to 2.
Specifically, the standard forehead temperature value is calculated according to forehead temperature values of M human bodies detected before the current moment. The standard forehead temperature value can be understood as a reference value of the detected forehead temperature value of the human body, and the standard forehead temperature value and the current forehead temperature value detected in real time can be fitted through a mathematical relationship, so that the body temperature value of the human body is obtained. The detected forehead temperature value is the forehead temperature value detected in real time under the current environment, the standard forehead temperature value is calculated according to the detected forehead temperature value, the factor of environment detection is considered, the standard forehead temperature value is stored in advance, and the method for obtaining the body temperature value of the human body is higher in accuracy than the method for obtaining the body temperature value of the human body by fitting the standard forehead temperature value and the current forehead temperature value detected in real time through a mathematical relationship.
In one embodiment, the detecting the current forehead temperature value of the human body comprises: calculating the forehead temperature average value of the M forehead temperature values as the standard forehead temperature value; or, calculating the forehead temperature median of the M forehead temperature values as the standard forehead temperature value. The experimental analysis shows that the forehead temperature value of the human body approximately follows normal distribution, the normal curve of the normal distribution is symmetrical left and right by taking the mean as the center, so that the mean value of M forehead temperature values can be calculated firstly and taken as the standard forehead temperature value, and the forehead temperature mean value represents the mean value of the M forehead temperature values. Or, the temperature median value of M temperature values may be used as the standard temperature value, and the temperature median value is a value that is intermediate among the M number, and it should be noted that the M temperature values are arranged in descending order according to magnitude, that is, half of the M temperature values are larger than the temperature median value, and half of the M temperature values are smaller than the temperature median value. If M is an even number, the median is the average of the two numbers in the middle.
Step S103, obtaining the current body temperature value of the human body according to the current forehead temperature value, the standard forehead temperature value and a pre-stored standard underarm lower body temperature value.
Specifically, because the factor that the axillary body temperature value of the human body changes with the environment is relatively small, a standard axillary body temperature value can be calculated in advance according to a plurality of collected axillary body temperature values of the human body, then the standard axillary body temperature value is stored in advance, and the current body temperature value of the human body is calculated according to the current forehead temperature value of the human body collected at the current moment, the calculated standard forehead temperature value and the pre-stored standard axillary body temperature value, wherein the current forehead temperature value is a body temperature measurement result corresponding to the human body. The method for calculating the standard armpit lower body temperature value can be used for calculating the mean value or the median value of the armpit lower body temperature values of a plurality of human bodies to serve as the standard armpit lower body temperature value.

In one embodiment, referring to fig. 2, before obtaining the standard forehead temperature value according to M forehead temperature values detected before detecting the current forehead temperature value, the method includes:
in step S201, an underarm body temperature value and a forehead temperature value of an initial user are obtained.
Specifically, the initial user is the first user or the first user stored in advance, which is acquired when the terminal device is put into use formally, for example, when the terminal device starts to measure the temperature by the human body temperature measurement method of the present application, the temperature value of the user's nail input by the staff is acquired, the user's nail stands right in front of the thermal imaging camera to acquire the forehead temperature value of the user's nail, and the armpit temperature value and the forehead temperature value of the user's nail are used as the armpit lower body temperature value or the forehead temperature value of the initial user's quota, or the armpit lower body temperature value and the forehead temperature value of the initial user stored in advance are acquired.
Step S202, calculating an initial standard forehead temperature value according to the armpit lower body temperature value, the forehead temperature value and the standard armpit lower body temperature value.
Specifically, after the terminal device is put into use formally, the forehead temperature value of the human body is detected by the thermal imaging sensor, and when M forehead temperature values are detected and after M forehead temperature values are detected, the standard forehead temperature value can be calculated according to the methods in the steps S101 to S103, and then the forehead temperature value detected in real time according to the standard forehead temperature value and the pre-stored standard axillary lower body temperature value is calculated to obtain the forehead temperature value corresponding to the human body as the body temperature measurement result. However, when the M individual temperature values have not been detected, the initial standard forehead temperature value can be calculated according to the armpit body temperature value and forehead temperature value of the initial user and the pre-stored standard armpit body temperature value.
In one embodiment, the calculation formula for calculating the initial standard forehead temperature value according to the armpit lower body temperature value, the forehead temperature value and the standard armpit lower body temperature value is as follows:
wherein, T isms0Represents the initial standard forehead temperature value, Ts0A value representing the forehead temperature, T, of the initial userr0Representing the initial user's underarm temperature value, TmrRepresents the standard axillary body temperature value, the

Step S203, calculating to obtain a body temperature value corresponding to the I-th volume temperature value according to the standard axillary body temperature value, the initial standard volume temperature value and the I-th volume temperature value; wherein the ith temperature value is any one of the M temperature values.
Specifically, after the terminal device is put into use formally, and when any one of the forehead temperature values of the human body is detected by the thermal imaging camera or the thermal imaging sensor at any time before the M forehead temperature values are detected, the forehead temperature value of the human body is regarded as the I-th forehead temperature value of the M forehead temperature values, and the body temperature value corresponding to the I-th forehead temperature value is obtained by calculation according to the standard axillary body temperature value, the initial standard forehead temperature value and the I-th forehead temperature value and is used as the body temperature measurement result of the human body.
In one embodiment, please refer to fig. 3, after determining the standard forehead temperature value, the method further includes:
step S301, after the current forehead temperature value is detected, when a new forehead temperature value is detected again, updating the M forehead temperature values through the new forehead temperature value.
Specifically, a new forehead temperature value is detected at a certain time after the current forehead temperature value is detected, and the M forehead temperature values are updated according to the new forehead temperature value.
In one embodiment, referring to fig. 4, when a new forehead temperature value is detected again in step S301, updating the M forehead temperature values by the new forehead temperature value includes steps S3011 to S3013:
and step S3011, selecting K forehead temperature values from the M forehead temperature values through a random selection algorithm to mark.
Specifically, the random algorithm may be a probability algorithm (e.g., a sherwood algorithm), K temperature values are selected from the M temperature values according to the random algorithm, and the selected K temperature values are marked, where K is less than or equal to M, and the size of K may be set in advance according to actual application.
Step S3012, selecting one forehead temperature value from the M forehead temperature values as a target forehead temperature value through a random selection algorithm, and detecting whether the target forehead temperature value is a marked forehead temperature value.
Specifically, in the marked K forehead temperature values and M forehead temperature values which are not selected as the forehead temperature values in the K forehead temperature values, through a random selection algorithm, one forehead temperature value is selected as a target forehead temperature value, and whether the selected target forehead temperature value is the marked forehead temperature value or not is judged.
Step S3013, if the forehead temperature value of the target human body is the marked forehead temperature value, replacing the target forehead temperature value with the new forehead temperature value when a new forehead temperature value is detected again, so as to update the M forehead temperature values.
Specifically, if the target forehead temperature value is the marked forehead temperature value, the newly detected forehead temperature value is used to replace the target forehead temperature value, so as to update the M forehead temperature values. Therefore, the M rated temperature values are updated by a probabilistic algorithm, and are not updated every time a new rated temperature value is detected, the stability of the algorithm is poor when the new rated temperature value is detected to update, the M rated temperature values are updated by the probabilistic algorithm, and the stability of the algorithm is high.
Step S302, updating the standard forehead temperature value according to the updated M forehead temperature values.
Specifically, the standard forehead temperature value is recalculated according to the updated M forehead temperature values, and the recalculated standard forehead temperature value is updated to the standard forehead temperature value.
In one embodiment, after the standard value is updated, obtaining the current body temperature value of the human body according to the current forehead temperature value, the standard forehead temperature value and a pre-stored standard axillary lower body temperature value comprises: and obtaining the current body temperature value of the human body according to the current forehead temperature value, the updated standard forehead temperature value and a pre-stored standard underarm lower body temperature value.
For example, the body temperature of a pedestrian needs to be measured in a certain place, specifically, the forehead temperature of the pedestrian can be detected by a thermal imaging sensor in a terminal device or a thermal imaging camera in communication connection with the terminal device, when the detection is started, the underarm body temperature value and the forehead temperature value of an initial user can be obtained first, for example, a user of the device inputs the underarm body temperature value of a user nail, then the user nail is allowed to stand right in front of the thermal imaging sensor or the thermal imaging camera to obtain the forehead temperature value of the user nail, the underarm body temperature value input by the user is used as the underarm body temperature value of the initial user, the detected forehead temperature value of the user nail is used as the forehead temperature value of the initial user, or if the underarm body temperature value and the forehead temperature value of the initial user are prestored, the underarm body temperature value and the forehead temperature value of the initial user can be obtained directly; calculating an initial standard underarm body temperature value according to the underarm body temperature value of the initial user, the forehead temperature value of the initial user and a pre-stored standard underarm body temperature value; after calculating the initial standard forehead temperature value, when detecting the forehead temperature value of the human body, calculating the corresponding body temperature value according to the pre-stored standard armpit lower body temperature value, the initial standard forehead temperature value and the detected forehead temperature value of the human body, and taking the corresponding body temperature value as the body temperature measurement result of the corresponding human body; when the detected forehead temperature value is equal to the M forehead temperature values, the M forehead temperatures can be understood as forehead temperature values of M detected individuals, a standard forehead temperature value is calculated according to the M forehead temperature values, and then the M individuals and the body temperatures after the M individuals obtain the current body temperature value of the corresponding human body as the body temperature measurement result of the human body according to the current forehead temperature value of the corresponding human body, the standard forehead temperature value and a pre-stored standard axillary lower body temperature value. It should be noted that, when the forehead temperature value of the human body is detected after the mth person is detected, the M forehead temperature values are updated according to the detected forehead temperature value of the human body, and the standard forehead temperature value is recalculated according to the updated M forehead temperature values, that is, the body temperature value of the human body detected after the mth person is also calculated according to the current forehead temperature value of the human body, the standard forehead temperature value, and the pre-stored standard axillary body temperature value, but the standard forehead temperature value is a dynamic value, that is, the standard forehead temperature value is updated along with the detected new forehead temperature value of the human body.
The embodiment of the application detects the forehead temperature value of a human body through a thermal imaging sensor; when M human body forehead temperature values are detected, determining standard forehead temperature values corresponding to the M human body forehead temperature values; wherein M is more than or equal to 2; after the standard forehead temperature value is determined, when the forehead temperature value of the human body is detected, the current body temperature value of the human body is calculated and obtained according to a pre-stored axillary body temperature standard value, the standard forehead temperature value and the currently detected forehead temperature value of the human body and serves as a current body temperature measurement result of the human body. Because the armpit body temperature value is not easily influenced by the environment, and the forehead temperature value is easily influenced by the environment, the standard forehead temperature value is determined through the M detected forehead temperature values, and the current body temperature value of the human body is obtained according to the standard forehead temperature value, the pre-stored standard armpit body temperature value and the current forehead temperature value, so that the accuracy of the body temperature measurement result can be improved.
