Infrared body temperature detection system and method based on image registration

Abstract

The invention belongs to the field of computer vision application, and discloses an infrared body temperature detection system and method based on image registration, the system comprises an image acquisition module, a data processing module and an output module, the image acquisition module is a binocular camera composed of an infrared temperature measurement camera and a true color camera, the binocular camera is connected with the data processing module, and the data processing module is connected with the output module. The method comprises the steps of image data acquisition, image detection and prompt, image data processing, image registration and fusion, temperature measurement result output and the like. The detection system is low in operation cost, can be normally used in a network-free environment, can remind a person wearing the cap to take off the cap and measure the temperature, and corrects systematic errors, so that the detected temperature data is more accurate; and according to the detection method provided by the invention, the positioning of the target infrared temperature measurement area is more accurate, and the detected temperature is more accurate. The system is suitable for body temperature detection of people moving in public areas.

Description

technical field [0001] The invention belongs to the field of computer vision applications and relates to body temperature detection, in particular to an image registration-based infrared body temperature detection system and detection method. Background technique [0002] Infrared imaging technology is a technology that detects the invisible infrared rays radiated from the surface of various personnel in public areas, and the body temperature information of public area personnel can be effectively reflected by infrared image B. [0003] Manufacturers of infrared detectors usually add a colorimetric bar on the thermal infrared image B. The colorimetric bar is used as the label of the thermal infrared image B, corresponding to the highest point and the lowest point of the temperature in the image. In theory, each pixel can be compared with the colorimetric The bars correspond to and obtain the corresponding temperature values. Since the temperature of the edge of the temperatu...
