Abstract

The invention provides a temperature correction method for an infrared thermal imaging detection system, the method comprising the following steps: setting a target temperature for a reference background, and making the actual temperature of the reference background reach the target temperature; obtaining the temperature of the reference background heat map; divide the heat map of the reference background into a plurality of regions, and obtain the average temperature value of each region; for each region of the heat map of the reference background, determine in turn the average temperature value of each region relative to Whether the error of the actual temperature of the reference background is within the allowable range; if the average temperature value of a certain area of ​​the heat map of the reference background exceeds the allowable range, then the average temperature value of the area is compensated for the average temperature of the area The difference between the actual temperature of the reference background and the actual temperature of the reference background, so that the compensated temperature of the region is consistent with the actual temperature of the reference background. The invention can effectively correct the temperature error of the system.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a temperature correction method for an infrared thermal imaging detection system. Background technique [0002] At present, the infrared thermal imaging detection system has been fully applied in the medical field. It can not only carry out early warning analysis for various diseases and sub-health states of the human body, but also does not produce any rays, does not cause harm to the human body, does not pollute the environment, and is simple. economy. [0003] Since the temperature distribution of the normal human body has certain stability and characteristics, the temperature of each part of the body is different, forming different thermal fields. When a disease or function changes somewhere in the human body, the blood flow in that place will change accordingly, resulting in a change in the local temperature of the human body, manifested as a high or low te...
