Abstract
The invention provides a medium and long wave infrared image fusion method and device applied to the ship detection field under a sea-sky background and relates to the field of ship detection technology. The method comprises the steps that a first image and a second image are acquired, wherein the first image and the second image are a medium wave infrared image and a long wave infrared image of ato-be-detected scene respectively; wavelet-Contourlet transformation is performed on the first image and the second image to obtain two image sets, wherein each image set comprises multi-scale multi-direction four-layer decomposition images of the first image or the second image; the decomposition images on the same layer of the two image sets are fused by use of the PCNN global coupling propertyand the synchronous pulse emission characteristic in combination with a structural similarity operator, and four fusion image layers are obtained; and the four fusion image layers are reconstructed to obtain a photographed image of the to-be-detected scene. Through fusion of the medium wave infrared image and the long wave infrared image, the instantaneity and motility of capturing the to-be-detected scene are enhanced, and the technical problem that an existing ship detection technology is poor in instantaneity and motility is relieved.
Description
technical field [0001] The invention relates to the technical field of ship detection, in particular to a medium and long wave infrared image fusion method and device applied to the field of ship detection under the background of sea and sky. Background technique [0002] The identification and monitoring of surface ship targets is an important part of the national ocean monitoring mission, and it is of great significance to the country's economic development, environmental protection, protection of maritime rights and interests, and the development of military power. [0003] Nowadays, the application of marine ship detection and dynamic monitoring puts forward higher requirements for the "real-time performance" and "mobility" of related monitoring and monitoring systems. The existing ship detection technology, in terms of hardware technology, low-orbit satellites have been difficult to meet the needs of related applications in terms of observation range, real-time performa...
