Problems solved by technology

First, the alarm temperature point in the infrared image is calculated through the image registration algorithm to calculate the corresponding position of the point in the visible light, and the visible light face detection algorithm is used to judge whether the alarm temperature point is in the alarm face area, thereby generating an alarm signal. The introduction of face detection has sol

Abstract

The invention relates to a human body temperature measuring method based on an infrared human face detection technology. The method comprises following steps: when over-temperature points appear on aninfrared image obtained by an infrared temperature measurer, judging whether the over-temperature points stay in a human face area of a moving infrared image in the infrared image; if the over-temperature points stay in the human face area of the moving infrared image, utilizing a matching algorithm to find an area, which is corresponding to the human face area in the infrared image, in a visiblelight image; using a visible light human face detection technology to judge whether a human face area exists in the area, which is corresponding to the human face area in the infrared image, in the visible light image; if the result is positive, taking the over-temperature points as alarming temperature points, and giving off an alarm. The false alarm caused by image matching and synchronizationbetween infrared light and visible light is avoided, and missed alarm caused by light and skin sensitivity of a visible light human face detection technology is prevented.

Description

technical field [0001] The invention relates to an intelligent detection technology in the field of infrared thermal imaging temperature measurement, in particular to a human body temperature measurement method based on infrared face detection technology. Background technique [0002] In temperature quarantine places such as border ports and airports, an infrared human body screening device with both infrared and visible light systems is usually used, and the host computer software of the human body screening device running on a computer is used to screen out people who are in the set The temperature point in the high temperature area of ​​the human body generates an alarm signal, marks the alarm temperature point with a cursor with temperature information in the infrared image and visible light image, performs operations such as over-temperature alarm sound and light prompts, over-temperature alarm snapshots, etc., and saves into the alarm database for future inquiries. Ac...
