Problems solved by technology
[0012] When comparing the feature points in the above-mentioned existing literature, the angle and length of the line segment formed by the link between the visible light feature point and the infrared feature point are used as the comparison condition, and finally the homography matrix applicable to the entire picture is calculated based on the compared points Homography matrix, using this matrix to convert infrared rays and fuse them with visible light images; however, when these documents deal with the automatic positioning and superposition of visible light and infrared images, they cannot automatically compare more than one human body to locate infrared rays on visible light images In the correct position, it is impossible to quickly realize human body recognition and at the same time realize human body temperature detection

Embodiment Construction
[0053] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0054] A real-time human body temperature rapid detection method of the present invention, first of all, after obtaining the simplified outline of the object in the visible light and infrared images, the cross-comparison of the outline is performed by dynamic programming, and then the infrared object is superimposed on the infrared object through the perspective projection conversion. On the visible light object with the highest similarity, and calculate the temperature of the human body, the specific implementation steps are as follows:
[0055] Step S1, capture the image with the infrared camera and the visible light camera, and obtain the infrared image and the visible light image; then use the Gaussian method to obtain the outline of the moving object on the visible light image; convert the color space of the infrared image from RGB to...

The invention relates to a real-time human body temperature rapid detection method. Firstly, performing cross-comparison on a contour with dynamic programming after obtaining a simplified contour of an object of visible light and infrared images; and then superimposing the infrared object on the visible light object with the highest similarity as the infrared object, and performing human body temperature calculation. The invention fuses the infrared and visible light images, therefore, the body temperature can be obtained, individual objects can be recognized, the identification efficiency canbe improved, and the human body temperature rapid detection can be realized.
Description
technical field [0001] The invention relates to a real-time human body temperature rapid detection method. Background technique [0002] In the existing infrared-based human body temperature detection method, since the image captured by the infrared camera is quite different from the visible light image, in the past, when the temperature was monitored through the infrared device, another camera had to be used to capture the visible light image, and then artificially Comparison and identification, in such occasions where there is a large flow of people, it is impossible to quickly realize human body recognition and simultaneously realize human body temperature detection. Together, save the troublesome way of manual comparison. [0003] The existing literature on the fusion of visible light images and thermal images includes: [0004] 1. Robust Face Recognition by Dynamically Adjusting the Fusion Ratio of Multiple Visible Light Images and Thermal Images, Shi Weizun Master Th...
