Self-calibration method of infrared thermal imaging body temperature monitor

Abstract

The invention discloses a self-calibration method of an infrared thermal imaging body temperature monitor. Automated calibration can be realized, meanwhile, before calibration, pedestrians are preliminarily judged according to the temperature information of a detection area acquired by the infrared thermal imaging body temperature monitor, that no pedestrian exists in the monitoring area is judged, if yes, automatic calibration is carried out, otherwise, that pedestrians possibly exist in the monitoring area is judged, whether pedestrians exist in the monitoring area or not is further judged through the infrared image S, if not, automatic calibration is carried out, and otherwise, pedestrian judgment is repeatedly executed till that no pedestrian exists in the monitoring area is judged, and then automatic calibration of the temperature is completed. The self-calibration method of the infrared thermal image body temperature monitor is advantaged in that the phenomenon of information missing report caused by stagnation in the calibration period can be avoided, the infrared thermal image body temperature monitor can continuously detect the body temperature of pedestrians in the view field range, and detection accuracy and stability are guaranteed.

Description

technical field [0001] The invention relates to the field of automatic calibration of infrared thermal imaging body temperature monitors, and in particular provides a self-calibration method for infrared thermal imaging body temperature monitors, in particular to a self-calibration method for infrared thermal imaging body temperature monitors in the process of monitoring abnormal body temperatures of pedestrians. Background technique [0002] With the increasing application of infrared thermal imaging technology in human body temperature measurement, abnormal body temperature detection is especially related to people's lives and social stability. Therefore, the requirements for the measurement accuracy and stability of infrared thermal imaging body temperature monitors are also getting higher and higher. , At present, the existing infrared thermal imaging body temperature monitor needs to be manually calibrated after running for a certain period of time. During the calibratio...
