Infrared thermal imaging detection system

Abstract

The invention provides an infrared thermographic testing system comprising an image acquisition device which is used for acquiring infrared radiation of a detected object and converting the acquired infrared radiation into electric signals; a computer device which is used for receiving electric signals related to the infrared radiation from the image acquisition device and processing the electric signals to generate thermograph signals; a display device which is used for receiving the thermograph signals from the computer device and generating thermographs according to the thermograph singles and displaying the thermographs to the external; and a background device which is used for providing uniform and stable background temperature environment; the thermograph of the background device is divided into multiple regions by the computer device; the average temperature value of each region is calculated and obtained; it is successively judged whether the error of the average temperature value of each region with respect to the actual temperature of the background device is within an allowable range for each region; temperature compensation is performed for regions where the average temperature is outside the allowable range. By means of the system of the invention, system temperature error can be effectively corrected.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically, to 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 temperature. According to thi...
