Problems solved by technology

At present, image fusion technology is still unsatisfactory in terms of theory and method. Among them, multi-source image fusion mainly has the problems of insufficient detail information and ringing effects, and defects in image fusion and sub-pixel positioning. For example, image fusion will appear Spectral distortion, sub-pixel positioning only obtains a classification map, which cannot be used for further processing; while the fusion result of the single wavelet fusion method has shortcomings such as spectral distortion

Embodiment Construction

[0029] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0030] A method for multispectral image fusion to realize three-dimensional reconstruction, comprising the steps of:

[0031] (1) Realize biorthogonal wavelet decomposition: perform N-layer biorthogonal wavelet decomposition on each two-dimensional image to form 3N+1 different frequency bands, including 3N high frequency bands and a low frequency band; two images are fused as For example, the specific fusion method is as figure 1 As shown, let A and B be the two original images, and F be the fused image, respectively perform biorthogonal wavelet deformation on each original image, and establish the biorthogonal wavelet tower decomposition of the image; the fusion of multiple images method and so on;

[0032] (2) Determining the fusion operator: Different ...

Abstract

The present invention discloses a method for realizing three-dimensional reconstruction by multi-spectral image fusion, comprising the following steps of: realizing biorthogonal wavelet decomposition; determining fusion operators; implementing HIS transform, and separation of space and spectral characteristics; combining bands; fusing a resulted image. After processing with the method for realizing three-dimensional reconstruction by multi-spectral image fusion, an internal structure of a three-dimensional structure is quite clear, and therefore digital effect of the multi-spectral image is optimal, and complementation of advantages of single spectrum information is realized.

Description

technical field [0001] The invention relates to an image fusion method, in particular to a method for realizing three-dimensional reconstruction through multispectral image fusion. Background technique [0002] With the expansion of image fusion and related technology application fields, image processing technology has become the object of study and research among engineering, computer science, information science, biology, medicine and other disciplines, and a lot of fruitful work has been done. Due to the low spatial resolution of mixed pixels and the problem of different objects with the same spectrum, the application of hyperspectral images is severely limited, so image fusion, sub-pixel localization and super-resolution reconstruction become particularly important, because they can enhance the resolution of hyperspectral images Rate. At present, image fusion technology is still unsatisfactory in terms of theory and method. Among them, multi-source image fusion mainly h...
