Problems solved by technology

[0002] Using an infrared camera for temperature measurement is an effective method for rapid temperature measurement in a large range. However, temperature measurement based on an infrared camera has the disadvantage of being affected by the environment. Light has good absorption characteristics, resulting in low absolute temperature measurement accuracy of infrared cameras in long-distance temperature measurement application scenarios, which seriously affects the popularization and application of infrared cameras in the field of outdoor large-scale human body temperature detection

Abstract

A self-calibration infrared body temperature rapid detection method and detection device, the detection device includes a visible light camera, an infrared light camera, an image processing and protocol conversion module and a host computer, wherein the visible light image information of the target is captured by the visible light camera, and the infrared The infrared light image information of the target is captured by the light camera; the visible light image information is processed by the image processing and protocol conversion module or the host computer to identify and locate the designated area of ​​the target, and the infrared light image information is processed to obtain the corresponding The measured temperature in the specified area of ​​the target; the measured temperature corresponding to the specified area of ​​the target is corrected by the self-calibration algorithm to obtain the actual temperature. The invention has the advantages of large measurement range, high precision and flexible and convenient networking.

Description

technical field [0001] The invention relates to the field of infrared light imaging and temperature measurement, in particular to a self-calibration infrared body temperature rapid detection method and detection device. Background technique [0002] Using an infrared camera for temperature measurement is an effective method for rapid temperature measurement in a large range. However, temperature measurement based on an infrared camera has the disadvantage of being affected by the environment. Light has good absorption characteristics, which leads to low absolute temperature measurement accuracy of infrared cameras in long-distance temperature measurement application scenarios, which seriously affects the popularization and application of infrared cameras in the field of outdoor large-scale human body temperature detection. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a self-calibration infrared body temperature...
