Abstract

The invention discloses a dual-light imaging system image registration method and device, and the method comprises the steps: obtaining an image of a target object through the dual-light imaging system, obtaining a first waveband image and a second waveband image of the target object, and obtaining the distance from the dual-light imaging system to the target object; according to the affine transformation parameters corresponding to the distance, cutting out corresponding image areas from the first waveband image and the second waveband image of the target object; and registering the first wave band image and the second wave band image of the target object according to the edge features contained in the image area cut from the first wave band image of the target object and the image area cut from the second wave band image of the target object. According to the image registration method and device for the dual-light imaging system, the registration precision can be improved, and the defects that in the prior art, the requirement for the stability of an imaging device framework is high, and the registration effect of a close-range target is poor are overcome. The invention further discloses a bifocal imaging system and a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image registration method and device for a dual-light imaging system. The present invention also relates to a dual-light imaging system, and also to a computer-readable storage medium. Background technique [0002] Dual-light image fusion technology can obtain imaging information from two different wavelength bands of light, and the imaging information of the two complement each other. Contains rich information content, improves spatial resolution, and enhances image details. Among them, image registration is the basic link of dual-light image fusion, and it is also an important part of image fusion. [0003] In the prior art, the image registration scheme used is to calculate a correction matrix based on the principle of geometric optics, and use the correction matrix to calibrate an image or an imaging device. This method has a simple algorithm, no special requir...
