Embodiment 1

[0046] The device for multi-color temperature measurement according to the present invention includes: at least two pixels 102, each pixel 102 contains N temperature measurement units, where N is a positive integer greater than or equal to 2; the first temperature measurement unit 103 Receive the first radiation energy to obtain the first thermal radiation information; the Nth temperature measuring unit receives the Nth radiation energy to obtain the Nth thermal radiation information; the first thermal radiation information is different from the Nth thermal radiation information; processing unit, the processing unit obtains the relative ratio or normalized distribution data of the specific radiation energy density according to the first thermal radiation information to the Nth thermal radiation information; the relative ratio or distribution data of the specific radiation energy density corresponds to the target object temperature information of corresponding points; said proce...

Embodiment 2

[0071] like Figure 4 As shown, in this embodiment, each pixel 102 may be a corresponding thermal imaging unit of at least two different thermal imaging cameras. In this way, the two temperature measurement units in each pixel 102 are physically separated. The temperature measurement units of the pixel 102 are distributed on at least two different thermal imagers; each thermal imager includes several temperature measurement units.

[0072] like Figure 4 As shown, a temperature measurement unit of the first thermal imager 108 receives the first radiant energy to obtain the first thermal radiation information; a corresponding temperature measurement unit of the second thermal imager 109 receives the second radiant energy to obtain Second thermal radiation information. The corresponding two temperature measuring units of the first and second thermal imagers 109 correspond to the same point on the object; the processing unit forms a The temperature information of the correspond...

Embodiment 3

[0075] In this embodiment, each temperature measurement unit can be a temperature measurement unit of different designs or different processes or methods or principles, as long as it is ensured that in the same pixel 102, the thermal radiation information of at least two temperature measurement units is different. Part of the information of the radiation curve, each temperature measurement unit of the multi-color temperature measurement device, and even different pixels 102 may be different. Mixed together, the temperature is measured by the processing unit according to the obtained radiation information.

Abstract

The present invention provides a device, method and storage medium based on multi-color temperature measurement, comprising: at least two pixels, each containing N temperature measurement units; the first temperature measurement unit receives the first radiant energy, Obtain the first thermal radiation information; the Nth temperature measuring unit receives the Nth radiation energy to obtain the Nth thermal radiation information; the first thermal radiation information is different from the Nth thermal radiation information; the processing unit, the processing unit according to The first thermal radiation information to the Nth thermal radiation information obtain the relative ratio or normalized distribution data of the specific radiation energy density; the relative ratio or distribution data of the specific radiation energy density corresponds to the temperature information of the corresponding point of the target object; The pixels and the processing unit form information about the temperature of the target object. The device based on multi-color temperature measurement in the present invention makes the temperature measurement result independent of the emissivity of the measured object, thereby improving the accuracy of temperature measurement.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a device, method and storage medium based on multi-color temperature measurement. Background technique [0002] At present, the working principle of the thermal imager is to receive the thermal radiation of an object within a certain wavelength range, and obtain the temperature of the object according to its energy. In order to obtain the correct temperature, the thermal imager generally needs to be calibrated in advance with an adjustable temperature black body (the ideal black body emissivity is 1). [0003] However, general objects are not ideal black bodies, and their emissivity is less than 1. The object also reflects the energy of the surrounding environment. Therefore, the traditional thermal imager actually measures the total energy received by the instrument within a certain wavelength range (within a certain solid angle), that is [0004] W=εW0+τW1 [0005] Whe...
