Problems solved by technology

[0003] At present, research on multi-band image fusion at home and abroad is mainly concentrated in the fields of long-wave infrared-medium-wave infrared, infrared-visible light, ultraviolet-visible light, etc. The systems that use infrared and ultraviolet signals to detect partial discharge at home and abroad only realize ultraviolet Imaging and infrared detection are two independent aspects of detection, and how to fuse the energy distribution image in the sun-blind ultraviolet region and the long-wave infrared heat distribution image is a difficult point in current research

Abstract

The invention relates to a feature point location and edge detection-based image fusion test method. The method comprises the following steps of: (1) building a test device, wherein the test device comprises an infrared camera and an ultraviolet camera, and the infrared camera is parallel to the ultraviolet camera in the aspect of optic axis; (2) putting fluorescent light tubes at four corners of a field of view of the ultraviolet camera to carry out feature point location so as to obtain image fusion parameters; (3) shooting an infrared image and an ultraviolet image and respectively preprocessing the infrared image and the ultraviolet image; and (4) fusing the infrared image and the ultraviolet image by utilizing the fusion parameters obtained in the step (2). Compared with the prior art, the method provided by the invention is good in fusion effect.

Description

technical field [0001] The invention relates to an image fusion method, in particular to an image fusion experiment method based on feature point positioning and edge detection. Background technique [0002] Image processing refers to the technology of performing a series of operations on images in order to achieve the desired purpose, which can be divided into analog image processing and digital image processing. Image fusion is a main branch of image processing, and has great application prospects in target recognition, robot vision, aerospace, remote sensing, etc. There are many methods of image fusion, and the simplest method of image fusion is the pixel-based original image averaging method, which can obtain very fuzzy fusion images. In 1983, Burt P proposed a multi-scale decomposition method, and fusion methods based on Laplacian pyramids, such as Laplacian pyramids, morphological pyramids, and gradient pyramids, continued to emerge. In the 1990s, the wavelet transfo...
