Abstract

The invention relates to a power transmission line satellite remote sensing image fusion method and device. The method comprises the following steps: obtaining a fusion image of a satellite remote sensing high-resolution panchromatic band image and a fusion image of a satellite remote sensing multispectral low-resolution image of a power transmission line; substituting the fused image of the satellite remote sensing high-resolution panchromatic band image and the fused image of the satellite remote sensing multispectral low-resolution image of the power transmission line into a pre-establishedpower transmission line satellite remote sensing image sparse fusion model, and obtaining different band images of the feature map corresponding to each high-resolution filter or each low-resolutionfilter; determining different waveband images of the high-resolution multispectral image based on the different waveband images of the feature map corresponding to each high-resolution filter or eachlow-resolution filter. According to the scheme, a proper regularizer capable of capturing structure correlation is provided by considering correlation in a multispectral image frequency band, the fusion speed is increased, and reliable data guarantee is provided for subsequent inspection of environmental hidden dangers of a satellite remote sensing channel of a power transmission line.

Description

technical field [0001] The invention relates to the field of remote sensing data fusion, in particular to a satellite remote sensing image fusion method and device for power transmission lines. Background technique [0002] In recent years, the spatial resolution and update frequency of satellite remote sensing have become higher and higher, and they have been gradually and widely used in transmission line body inspection and channel inspection. In practical applications, transmission lines are weak targets in satellite remote sensing images, and their information needs to be enhanced to achieve high-precision inspections. [0003] Usually, high spatial resolution (HR) panchromatic satellite remote sensing imagery (PAN) with a single broadband channel contains accurate spatial details, while low spatial resolution (LR) multispectral satellite remote sensing imagery (MS) due to the difference in spatial and spectral resolution Physical compromises can provide more spectral p...
