The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:
fig. 1 shows a flow chart of a body temperature measurement method according to an embodiment of the present application, which may be performed by a temperature measuring instrument, which may be a forehead thermometer, an infrared detector, or the like. Referring to fig. 1, the body temperature measuring method at least includes steps S110 to S140, which are described in detail as follows:

In step S120, a compensation coefficient is determined based on the pigment content and the body surface temperature.
In one embodiment of the present application, the compensation factor is used to adjust the body surface temperature to determine the current, accurate, actual body temperature of the subject.
In one embodiment of the present application, determining a compensation factor based on the pigment content and the body surface temperature comprises: determining the content ratio corresponding to each pigment based on the pigment content corresponding to each pigment; determining the total proportion corresponding to the pigments based on the content proportion corresponding to each pigment; a compensation factor is determined based on a product between the total ratio and the body surface temperature.
In an embodiment of the application, the content of the pigment influences the infrared radiation of the forehead or the cochlea part, the temperature compensation coefficient is determined based on the content of the pigment and the body surface temperature in the embodiment, the coefficient is correspondingly processed with the signals received by the infrared receiving tube, the temperature of the forehead or the cochlea of the human body obtained in the way is highly close to the actual temperature inside the human body, the accuracy of the infrared forehead thermometer (or the ear thermometer) for measuring the body temperature of the human body is greatly enhanced, and errors within 0.1 degree can be achieved through a large amount of clinical verification and comparison of the human body.

In this embodiment, the body surface temperature of the body surface of the object measured by the infrared sensor is X, the ambient temperature is Y, the coefficients of the corresponding pigments at the current ambient temperature Y are a, b, c, and d, respectively, and the compensation coefficients obtained based on the coefficients of the corresponding pigments at the body surface temperature X and the current ambient temperature Y are: z ═ X (a + b + c + d).
In step S130, the actual body temperature of the subject is determined based on the ambient temperature, the body surface temperature, and the compensation coefficient.
In an embodiment of the present application, the ambient temperature and the body surface temperature both have their corresponding coefficients, and in this embodiment, the coefficient of the ambient temperature is not changed, but the coefficient of the body surface temperature is changed according to the difference of the ambient temperature, which is specifically shown in table 2:
