Hyperspectral image unmixing method and device and electronic equipment

Abstract

The invention is suitable for the field of hyperspectral image unmixing, and provides a hyperspectral image unmixing method and device and electronic equipment. The method comprises the following steps: establishing an objective function in a decision space according to an unmixing target of a hyperspectral image and an abundance vector of each mixed pixel in the hyperspectral image; establishing an initialized population in the decision space, and generating an initial weight vector set according to the initialized population; generating a next-generation population and a next-generation weight vector set according to the target function and the initial weight vector set; performing weight expansion on bottleneck weight vectors in the next-generation weight vector set to obtain an expanded weight vector set; and taking the next-generation population as an initialized population, taking the extended weight vector set as an initial weight vector set, repeatedly executing the two steps until a preset ending condition is met, and determining an optimal abundance vector corresponding to each mixed pixel according to the obtained next-generation population. According to the method provided by the invention, the accuracy of hyperspectral image demixing can be improved.

Description

technical field [0001] The present application belongs to the technical field of hyperspectral image unmixing, and in particular relates to a hyperspectral image unmixing method, device and electronic equipment. Background technique [0002] Hyperspectral resolution remote sensing, referred to as hyperspectral remote sensing, is a technology that uses a narrow and continuous spectral channel to continuously image ground objects. The images produced by hyperspectral remote sensing are called hyperspectral images. Although the spectral resolution of the hyperspectral image is high, the spatial resolution of the object corresponding to the pixel is relatively low, which leads to the widespread existence of mixed pixels, that is, a pixel may be of several types mix. The problem of mixed pixels is not only an important obstacle to the further development of remote sensing technology to quantification, but also seriously affects the application of computer technology in the fiel...
