Problems solved by technology

However, a large number of existing infrared thermal diagnostic equipment avoids this in application, which results in the lack of a unified comparison basis for the temperature maps obtained on the surface of each test object, and it is difficult to say that a specific temperature value represents disease state of the human body
Therefore, it can be considered that an important task in the current diagnosis of disease fever is to correctly interpret the internal relationship between body surface temperature and various disease states, and discussing this without environmental factors will obviously greatly reduce the diagnostic conclusion

Embodiment 1

[0027] The invention mainly provides a solution to the infrared image distortion problem existing in the current infrared imaging equipment. Research and experiments on various factors that affect infrared measurement have found that there are many external factors that affect infrared imaging, such as temperature, humidity, wind speed, light, etc. Therefore, the present invention proposes a standardized infrared imaging method for artificially controlling the external environment during the infrared imaging test. The method comprises the steps of:

[0028] 1) Adjust the test environment of infrared imaging to a given value. The given value can be obtained through experiments, and the preferred given value is: temperature is 27°C±0.5°C; humidity is 30%±3%; wind speed is 0.001-0.01m / s.

[0029] 2) Evenly spread a layer of paste-like substance with an emissivity close to a black body on the surface of the target to be measured (such as the surface of human skin), and the emiss...

Embodiment 2

[0037] The standardized infrared imaging method of this embodiment is consistent with that of Embodiment 1.

[0038] The miniaturized device of the standardized infrared thermographic imaging system provided in this embodiment. Such as figure 2 As shown, the standardized infrared thermographic imaging device of this embodiment is composed of an infrared imager 1 and a micro-environment control box 12 . The micro-environment control box 12 includes: a heating power supply 13 ; a temperature and humidity sensor 9 ; a hygroscopic material 14 ; and a heating wire 15 . The micro-environment control box is a cylindrical device integrated with the infrared camera of the infrared imager, its cross-sectional size matches the infrared camera, and the outer diameter of the infrared camera is the same as the inner diameter of the micro-environment control box (or slightly smaller , to ensure that the infrared camera can be stuck in the micro-environment control box), the cross-sectiona...

Abstract

The invention relates to an infrared thermal map imaging method for a target surface and a system thereof; the infrared thermal map imaging method comprises that the testing environment of the infrared imaging is regulated so as to cause the temperature, moisture and wind speed of the environment of the target to be tested to be a preset standard state; the surface of the target to be tested is evenly coated with a layer of paste substance; the emissivity of the paste substance approaches to black body; an infrared imaging instrument is used for carrying out the infrared imaging of the surface of target to be tested so as to obtain a standardized infrared thermal map; the system of the invention comprises an infrared imaging instrument and a closed standard environment cavity; the standard environment cavity is provided with a temperature regulating component, a moisture regulating component, a temperature sensor and a moisture sensor. The method and the system of the invention control the external environment of the target to be tested in an all-around way and the infrared image obtained by the infrared imaging instrument is based on a uniform benchmark, thereby obtaining a body surface thermal map which has a uniform comparison basis and avoiding misdiagnosis and error diagnosis. The method and the system of the invention have significant value in improving the accuracy of the early diagnosis of tumor.

Description

technical field [0001] The invention belongs to the application field of medical equipment, in particular, the invention relates to a method and system for obtaining a standardized infrared heat map by imaging a target surface (such as the surface of a human body) with an infrared heat map. Background technique [0002] At present, in the field of disease diagnosis, thermal imaging medicine is developing rapidly. Among various detection methods, the use of infrared to quantitatively measure the temperature field of the body surface and judge the disease is a large category of methods that have attracted high attention. For example, infrared measurement during SARS Thermometer application. This diagnostic method is widely recognized for its non-invasive and painless advantages, but one of the main problems at present is that the diagnostic accuracy is still unsatisfactory. When the existing infrared equipment is used, the difference of time and place is not considered. When ...
