[0045]

[0046] In the above steps, when the ambient temperature is not recorded as the target ambient temperature and the actual temperature of the object to be measured is the first temperature in the correspondence table, the first parameter of the target correction method required to determine the target temperature is obtained through a predetermined correspondence table and a threshold value, thereby enhancing the adaptability of the temperature measurement method to different ambient temperatures and actual temperature changes of the object to be measured, improving the flexibility and universality of temperature correction, simplifying the correction process, reducing human intervention, and effectively improving the efficiency of temperature correction.

[0047] In an optional embodiment, before determining the first parameter value corresponding to the first temperature and the target ambient temperature based on a preconfigured temperature-parameter correspondence table, the method further includes: determining the emissivity range of the first object corresponding to each of a plurality of first relationship tables, wherein the emissivity of the first object corresponding to each of the first relationship tables is not completely the same, and each of the first relationship tables records the parameter values ​​determined by the target device under a plurality of second conditions, and the ambient temperatures under different second conditions are not completely the same as the measured temperatures of the object to be measured, and the parameter value under each of the second conditions is obtained by fitting the temperatures and emissivities of each of the first objects measured by the target device at the same ambient temperature for a plurality of first objects with actually the same surface temperature and different emissivities; and determining the correspondence table according to the first relationship table including the target emissivity in the emissivity range.

[0053]

[0054] Among them, A, B, and C are the first parameters, and ε is the target emissivity.

[0055] The following is an exemplary description of the solution in this application in conjunction with specific embodiments:

[0056] Figure 3 is a flowchart of a method for determining a first relationship table according to an embodiment of the present invention. Figure 3 As shown, the method includes:

[0057] Step S302, determining a plurality of target radiation materials with different emissivities, a plurality of different target temperatures to which the surface of the target radiation material is heated, and a plurality of different ambient temperatures of the target radiation materials during temperature measurement;

[0058] Step S304, placing the multiple target radiation materials under multiple conditions, and determining temperature values ​​obtained by measuring the surface temperature of the multiple target radiation materials under each condition with the infrared thermal imager, wherein the surface temperature of the target radiation material and the ambient temperature under each condition are different;

[0059] Step S306, substituting the temperature values ​​of the various target radiation materials and the emissivity of the various target radiation materials measured by the infrared thermal imager under each condition into formula (1): , to obtain the parameters A, B, and C corresponding to each condition in the first relationship table, wherein T is the surface temperature to which the various target radiation materials are heated as measured by the temperature measuring device.

[0060] In the above step S302, the target radiation material includes but is not limited to: a plurality of materials with different emissivities of the same length, width and thickness, wherein the emissivity of the target radiation material and the distribution interval of the emissivity can be determined according to the emissivity distribution of the object measured by the infrared thermal imager, for example, selecting materials with emissivities of 0 to 1 with an interval of ∆ε, selecting materials with emissivities of 0.1, 0.2, 0.3 ..., 0.9, 1 with an interval of ∆ε=0.1, or selecting materials with emissivities of 0.01, 0.02, 0.03 ..., 0.99, 1 with an interval of ∆ε=0.01. Exemplarily, the emissivity value interval of the target radiation material can be adjusted in combination with the application scenario, for example, selecting materials with an interval of ∆ε=0.1 in the emissivity interval of 0 to 0.5, and selecting materials with an interval of ∆ε=0.02 in the emissivity interval of 0.5 to 1. The distribution of the multiple target temperatures (e.g., the temperature range and the temperature distribution method within the range) and the distribution of the multiple ambient temperatures (e.g., the temperature range and the temperature distribution method within the range) can be set in combination with the application scenario. Exemplarily, the value range of the target temperature includes the commonly used temperature measurement temperature of the infrared thermal imager, and / or includes multiple temperature points distributed within the upper and lower limits of the temperature measurement of the infrared thermal imager. For example, the value range of the target temperature can be an arithmetic progression uniformly distributed within the upper and lower limits of the temperature measurement, and a commonly used temperature measurement interval of the infrared thermal imager. For example, multiple temperature points can be set within the commonly used temperature measurement interval of the infrared thermal imager, and the setting of temperature points can be reduced in the uncommon temperature measurement interval. Exemplarily, the ambient temperature can be selected at intervals of 10°C, or at intervals of 5°C, or only a few specific ambient temperatures can be selected, for example, normal temperature 25°C, upper limit working temperature, and lower limit working temperature.

[0061] In the above step S304, for example, when the ambient temperature is 25°C, materials with different emissivity are placed at the infrared thermal imager calibration distance facing the infrared thermal imager. The surface of the target radiation material is heated or cooled to the target temperature and kept in a stable state by using a heating device or a cooling device, and the temperature of the target radiation material is measured by an infrared thermal imager, so as to obtain the temperature of materials with different temperatures and different emissivity collected by the infrared thermal imager under different ambient temperatures.

[0062] In the above step S306, T is the surface temperature of the various target radiation materials measured by a temperature measuring device that uses the infrared temperature measurement principle to measure temperature.
