This application relates to the field of artificial intelligence technology, and provides a temperature detection method and device based on visible light images and thermal imaging images, including collecting visible light images of users based on visible light cameras, and collecting thermal imaging images of users based on thermal imaging cameras; detecting visible light The coordinates of the user's forehead in the visible light image in the image; based on the visible light image, the distance between the user and the visible light camera is detected; based on the coordinates of the user's forehead in the visible light image and the distance between the user and the visible light camera, the calculated distance between the user's forehead The coordinates in the imaging image; the thermal imaging temperature at the coordinate position of the user's forehead in the thermal imaging image is obtained as the temperature detection result of the user. This application converts the coordinates of the user's forehead in the visible light image to obtain the coordinates of the user's forehead in the thermal imaging image. At the same time, this application measures the temperature of the forehead position, making the temperature measurement result more accurate.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a temperature detection method and device based on visible light images and thermal imaging images. Background technique [0002] At present, on temperature measurement devices such as temperature measurement and face recognition all-in-one machines, the camera preview screen and face frame position prompts are indispensable user experience, especially on temperature measurement and face recognition all-in-one machines, because the temperature measurement module is a fixed position And the visible range, when the face frame is not in the middle of the preview screen, it will cause inaccurate temperature measurement. At the same time, the visible light camera and the thermal imaging camera on the temperature measurement equipment cannot overlap, and there must be a certain horizontal distance, that is, the images collected by the visible light camera and ...
