Embodiment

[0028] In this embodiment, a three-dimensional infrared thermal imaging detection method of human skin epidermis and subcutaneous muscle layer, such as figure 1 shown, including the following steps:

[0029] S1. Use the 3D scanning device 21 to scan the part of the object to be measured 20 to obtain three-dimensional point cloud data, and process the three-dimensional point cloud data to generate a three-dimensional model of the part to be measured of the object to be measured 20;

[0030] S2. Perform surface cooling treatment on the part to be measured of the measured object 20;

[0031] S3. After completing the surface cooling treatment of the part to be measured of the measured object 20, use the infrared thermal imager 22 to shoot the infrared thermal imaging video of the part to be measured of the measured object 20 until the surface temperature of the part to be measured of the measured object 20 does not change significantly Stop shooting, and the infrared thermal imag...

Abstract

The invention relates to a three-dimensional infrared thermal imaging detection method for the human skin epidermis and subcutaneous muscle layers. The method comprises the following steps of adopting3D scanning equipment for scanning a to-be-tested part of a tested object to obtain three-dimensional point cloud data, and processing the three-dimensional point cloud data to generate a three-dimensional model of the to-be-tested part of the tested object; conducting surface cooling on the to-be-tested part of the tested object; adopting an infrared thermal imager to shoot infrared thermal imaging videos of the to-be-tested part of the tested object after cooling treatment is completed; according to the infrared thermal imaging videos, conducting inversion calculation through a biological tissue thermal conduction Pennes equation to calculate temperature distribution inside biological tissue of the to-be-tested part of the tested object, and reconstructing a three-dimensional temperature field in the to-be-tested part of the tested object; conducting registering and merging on the three-dimensional model of the to-be-tested part of the tested object and the internal three-dimensional temperature field to obtain a three-dimensional infrared thermal imaging model for the epidermis layer and subcutaneous muscle layer of the tested object to provide a basis for further diagnosis ofa doctor.

Description

technical field [0001] The invention relates to the technical field of infrared thermal imaging of human body, and more specifically, to a three-dimensional infrared thermal imaging detection method of human skin epidermis and subcutaneous muscle layer. Background technique [0002] Infrared thermal imaging technology has been widely used in the medical field to detect the temperature of the human epidermis. Doctors make corresponding diagnoses based on the detected temperature data of different regions of the human epidermis. However, the existing human body infrared thermal imaging technology can only detect the thermal imaging data of the epidermis of the measured object, but cannot detect the thermal imaging data below or inside the epidermis of the measured object, making it impossible for doctors to make further diagnoses. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a three-dimen...
