Abstract

The invention discloses a double-spectrum image alignment method. The method comprises the following steps: respectively acquiring a visible light image and an infrared image shot by image acquisitionequipment for a calibration plate, the calibration plate being provided with a calibration hole; extracting position information of calibration holes in the visible light image and the infrared image; calculating a scaling parameter and an offset parameter between the visible light image and the infrared image by utilizing the position information; and adjusting the visible light image and/or theinfrared image by using the scaling parameter and the offset parameter to enable the calibration plate in the visible light image to coincide with the calibration plate in the infrared image. According to the method, the mode of shooting the same calibration plate is adopted to guarantee that calibration plate information in the visible light image and the infrared image is consistent, alignmentparameters of the visible light image and the infrared image used for dual-spectrum image alignment are calculated through the information, and the complexity of dual-spectrum image alignment is reduced; the invention also discloses a dual-spectrum image alignment device, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the field of bispectral image alignment, in particular to a bispectral image alignment method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of sensor technology, the application scenarios of multi-band image fusion technology are gradually expanding, and the application value is gradually increasing. For example, visible light images can provide texture information of different objects in complex scenes, which is more suitable for the extraction of regions of interest, while infrared images can obtain temperature information in pictures. In the application scenario of human body temperature measurement, visible light images can be used to extract face information, and infrared images can be used for temperature calculation, which can effectively solve the problem of low temperature measurement efficiency of traditional mercury thermometers, ear thermometers or fo...
