Problems solved by technology
It can be seen that the theoretical basis is too simplistic compared to the complex human tissue, without considering the influence of some physical parameters of the tissue itself, and the use process is complicated, resulting in large errors, which needs further development and improvement

Embodiment Construction
[0019] Such as figure 1 As shown, the method for acquiring the depth of heat sources in biological tissues based on infrared thermal imaging in the present invention, the steps are as follows:
[0020] The first step is to set a normal-temperature object with a color similar to that of the biological detection object at the shooting site, and use a black body with a specified temperature as the background of the normal-temperature object, and use an infrared camera to capture the detection object and the normal-temperature object in the same grayscale image, and obtain Grayscale image. Simultaneously record the natural temperature and black body temperature of the shooting site.
[0021] The second step, according to the gray value of each pixel in the gray image obtained in step 1, obtain the coordinates of the pixel with the highest gray value in the gray image, and then obtain the gray value according to the coordinates of the pixel with the highest gray value The coordin...

The invention provides a method for obtaining the depth of an internal heat source of biological tissue on the basis of infrared thermal imaging. According to the method, a relational expression among the surface temperature difference, the depth of the internal heat source and the strength of the internal heat source is obtained on the basis of a classic biological heat transfer theory, a grayscale image is extracted through an infrared video camera, the grayscale of each pixel is extracted, grayscale segmentation is carried out, distribution of temperature points is detected, data are substituted into the relational expression among the surface temperature difference, the depth of the internal heat source and the strength of the internal heat source, and the depth of an abnormal temperature point is obtained. According to the method for obtaining the depth of the internal heat source of the biological tissue on the basis of infrared thermal imaging, the depth of the internal heat source of the biological tissue can be easily obtained only according to the environment object temperature, the black body temperature, grayscale distribution and the like.
Description
technical field [0001] The invention belongs to the technical field of infrared thermal imaging, and in particular relates to a method for acquiring the depth of heat sources in biological tissues based on infrared thermal imaging. Background technique [0002] The existing medical infrared thermal imaging technology can qualitatively diagnose internal lesions through infrared thermal images of the temperature distribution of the human body surface, but cannot obtain information about changes in the internal temperature of the tissue and lesions, and cannot locate the lesions. [0003] In 1997, developed the world's first thermal tomography imaging system (ThermalTextureMapsSystem), also known as TTM system. The principle of the system is to use the infrared thermal radiation receiving scanner to receive the infrared radiation of the human body, based on specific rules and algorithms to reconstruct the distribution map of the relative metabolic intensity of the cells corresp...
