Specifically, the correspondence between the radiation parameter of the radiation reference source and the temperature at the current radiation wavelength can be determined according to the reference radiation parameter and the reference temperature of the radiation reference source, and because the radiation specification of the radiation reference source is the same as that of the temperature measurement object, the temperature of the temperature measurement object, that is, the body temperature of the temperature measurement object, can be determined according to the radiation parameter of the temperature measurement object based on the correspondence between the radiation parameter of the radiation reference source and the temperature.
In the existing human body temperature measurement method, a blackbody radiation source is often used as a reference source, but the radiation characteristic of the blackbody radiation source is different from that of a measured object, for example, compared with the measured object, the emissivity of the blackbody radiation source is usually too high, the reflectance is usually too low, and the radiation characteristic is different from that of the measured object, so that the corresponding relation between the radiation characteristic and the temperature of the measured object cannot be obtained, and the blackbody radiation source is used as the reference source, so that the measured temperature is inaccurate. And the radiation reference source with the same radiation characteristic as the temperature measuring object is used as the reference source, so that the accuracy of the body temperature measuring result of the measured object can be improved.

Referring to the schematic illustration of the thermometry principle shown in fig. 3, in a thermometry field of view of the radiation thermometry device at the thermometry object and the radiation reference source, in a preferred embodiment, the radiation measurement device further includes a blackbody radiation source having the same temperature as the radiation reference source when performing body temperature measurement on the thermometry object, the radiation reference source includes a constant temperature heater and a simulated skin, the constant temperature heater is used for heating the simulated skin in the radiation reference source, and in step 200, before acquiring the reference temperature and the reference radiation parameter of the radiation reference source, the radiation measurement device may further include:
and step 01, controlling the constant temperature heater to heat the temperature of the radiation reference source to the reference temperature according to a preset reference temperature.
Before the reference temperature of the radiation reference source is acquired, the constant temperature heater is controlled to operate according to the preset reference temperature, so that the temperature of the radiation reference source is heated to the reference temperature. The control mode of the constant temperature heater comprises PID (proportion, integral and differential) control. Specifically, the simulated skin is closely attached to a constant temperature heating surface of the constant temperature heater, a temperature sensor is arranged on the constant temperature heating surface, and the temperature is controlled to be at a set constant temperature through PID control. The constant temperature is generally set within a normal temperature range of the object to be measured, such as about 36.5 ℃. If used for temperature screening, the temperature may be set to a critical value to increase screening accuracy, and the temperature of the blackbody radiation source may be set to be the same as the simulated skin, i.e., the reference temperature of the radiation reference source.
Further, in step 300, the determining the body temperature of the subject according to the target radiation parameter, the reference temperature and the reference radiation parameter specifically further includes:
step 301, acquiring a radiation formula of the blackbody radiation source;
step 302, determining the body temperature of the temperature measurement object according to a preset algorithm according to the target radiation parameter, the reference temperature, the reference radiation parameter and the radiation formula; the preset algorithm comprises the following formula:
L e,ref -L e,x ＝ε ref L bb (λ,T t,ref )-ε x L bb (λ,T t,x )
wherein L is e,ref Epsilon for the reference radiation intensity of the radiation reference source ref For the reference emissivity of the radiation reference source, T t,ref A reference temperature for the radiant reference source; l (L) e,x Epsilon for the target radiation intensity of the object to be measured x For the target emissivity of the temperature measuring object, T t,x A body temperature of the temperature measurement object; lambda is the radiation wavelength of the blackbody radiation source, L bb (λ,T t,ref ) And L bb (λ,T t,x ) For the blackbody radiatorRadiation formula of the source.
It will be appreciated that the radiation thermometry device measures the intensity L of infrared radiation of the measured object e Referring to the following equation 2, the intensity of infrared radiation L e Related to a number of factors:
L e ＝εL bb (λ,T t )+ρL am (2)
in formula 2, L e For radiation intensity, ε is emissivity of the measured object, L bb (λ,T t ) Is the radiation formula of an ideal blackbody radiation source, lambda is the radiation wavelength of the combined radiation source, T t For the temperature of the measured object to be solved, ρ is the reflectance of the measured object, L am Is an environmental factor.
In the existing radiation temperature measurement mode, generally, assuming that the object to be measured is an ideal diffuse reflector or lambertian body, epsilon=1- ρ exists, so that the formula 2 can be further simplified. However, this is not actually the case, and although there is a total emissivity=total absorptivity=1-reflectance of the object, the integral value of energy only at all wavelengths is applied to the formula, but at a specific certain wavelength, the formula is not true. For equation 2, it is the temperature T of the measured object that needs to be solved t In the existing mode, a blackbody radiation source is used as a reference source, and two variables of the reflectance and emissivity of a measured object cannot be obtained, so that the measured temperature error is high. In the schematic diagram shown in fig. 2, when using simulated skin, a relative measurement method can be used, i.e., formulas 3 and 4 can be derived based on formula 2:
L e,ref ＝ε ref L bb (λ,T t,ref )+ρ ref L am (3)
L e,x ＝ε x L bb (λ,T t,x )+ρ x L am (4)
in equations 3 and 4, L e,ref Representing the radiation intensity, L, of a radiation reference source e,x Representing a target radiation intensity of the thermometry object; epsilon ref For reference emissivity of the radiation reference source epsilon x The target emissivity of the temperature measuring object; l (L) bb (λ,T t,ref ) AndL bb (λ,T t,x ) A radiation formula representing a blackbody radiation source, λ being a radiation wavelength of the blackbody radiation source; t (T) t,ref For radiating the reference temperature of the reference source, T t,x The temperature of the temperature measuring object, namely the body temperature of the temperature measuring object; ρ ref For reference reflectance of the radiation reference source ρ x The target reflectance is the temperature measurement object; l (L) am Is an environmental factor.
Since the radiation characteristic of the radiation reference source is the same as that of the object to be measured, epsilon when the blackbody radiation source is fixed ref And epsilon x Identical ρ ref And ρ x The same; subtracting equations 3 and 4 by a relative measurement method to obtain equation 1, namely:
L e,ref -L e,x ＝ε ref L bb (λ,T t,ref )-ε x L bb (λ,T t,x )
equation 1 is a preset algorithm for calculating the body temperature of the temperature measurement object in the method for measuring the body temperature of the human body. Radiation intensity L of the radiation reference source based on the relative measurement algorithm shown in formula 1 e,ref Target radiation intensity L of temperature measurement object e,x Reference emissivity epsilon of a radiation reference source ref And the target emissivity epsilon of the object to be measured x The reference temperature T of the radiation reference source can be obtained through measurement t,ref It is known that the body temperature of a subject to be measured can be determined after the radiation formula of the blackbody radiation source is obtained. In the algorithm, based on the simulation effect of the radiation reference source, the influence of the emission ratio of the environmental factor and the temperature measurement object on the temperature measurement result can be counteracted, and the accuracy of body temperature measurement is further improved.
In this embodiment, based on the simulation effect of the radiation reference source, when the body temperature of the temperature measurement object is measured, the relative measurement method is adopted, so that the influence of environmental factors and the emission characteristic of the temperature measurement object on the measurement result can be ignored, and the accuracy of the body temperature measurement result of the temperature measurement object is improved.
