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, which can realize automatic calibration. At the same time, before the calibration, pedestrians are initially judged by the temperature information of the detection area obtained by the infrared thermal imaging body temperature monitor. If it is determined that there are no pedestrians in the monitoring area, perform automatic calibration; otherwise, determine that there may be pedestrians in the monitoring area, and further judge whether there are pedestrians in the monitoring area through the infrared image S, if not, perform automatic calibration, otherwise, repeat the execution for pedestrians Judgment until it is determined that there are no pedestrians in the monitoring area to complete the automatic calibration of the temperature. The self-calibration method of the infrared thermal imaging body temperature monitor can avoid the phenomenon of information omission caused by the jam during the calibration period, and can realize the continuous detection of the pedestrian body temperature within the field of view by the infrared thermal imaging body temperature monitor, ensuring the accuracy of the detection accuracy and stability.
