Abstract

The invention provides an image fusion method. By decomposing the visible image and infrared image through finite discrete shear wave transform, the high frequency sub-band coefficients and the low frequency sub-band coefficients of the corresponding images are obtained, the low-frequency sub-band coefficients of infrared image and visible image are fused, the high-frequency subband coefficients of infrared image and visible image are fused, The fused image is obtained by finite discrete inverse transform of the low frequency subband coefficient of the fused image and the high frequency subband coefficient of the fused image, the fusion image can display the environment information and contour details of each part of the equipment, which can improve the discrimination and facilitate observation. The finite discrete shear wave transform is realized by two-dimensional Fast Fourier Transform, and the calculation process is relatively simple.

Description

technical field [0001] The present invention relates to image processing, in particular to an image fusion method, device, computer equipment and storage medium. Background technique [0002] With the development of electronic system informatization and intelligence, power equipment status monitoring and fault diagnosis are important ways to avoid power supply paralysis, reduce power outage time and prolong the service life of power equipment, and are an important part of smart grid and smart substation construction. Many faults of power equipment are related to high-resistance heating. Therefore, temperature characteristics can be used as an important tool and indicator for power equipment status management. Among them, infrared imaging technology uses the thermal radiation of equipment, which can effectively identify thermal targets and detect the local temperature difference characteristics of power equipment, but the image contrast is low, and the edge contour details ar...
