Abstract

The invention provides a correction device of infrared and visible image registration parameters. The positions of an infrared detector and a visible detector are arranged in different angles, on the premise of guaranteeing that optical axes are parallel to each other, an image of a chessboard-shaped correcting target is shot, translation and zooming correction parameters of a visible image are calculated according to the distance between the chessboard-shaped correcting target and the correction device and image ghosting, the obtained parameters can realize adaptive registration of an infrared image and the visible image in an infrared and visible image fusion system, the registration correction of the detectors with different fixed forms can be realized, the registration of targets with different depths of field can be performed, the image data volume is reduced, and the operation speed is accelerated.

Description

technical field [0001] The invention belongs to the field of image registration, in particular to an infrared and visible light image registration parameter correction device and correction method. Background technique [0002] Image registration is one of the bottlenecks of infrared and visible light image fusion technology. It can effectively match and superimpose visible light images and infrared images, and provide highly correlated image data in space and time for subsequent fusion processing, which can solve fusion problems. The problems of blurred images, poor quality, and not conforming to the visual habits of the human eye have attracted the attention of scientific researchers from all over the world. [0003] Infrared and visible light image registration belongs to multimodal image registration, and there are two main types of registration methods: methods based on image regions and methods based on image features. Image region-based registration methods usually u...
