Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] like figure 1 As shown, in this embodiment, a method for video super-resolution reconstruction oriented to satellite cameras is provided, including:

[0052]Step S1. The resolutions of the nth frame image, the n-1th frame image and the n-2th frame image in the video are respectively enlarged by preset multiples to obtain the first image, the second image and the third image, and n is greater than or equal to 3 ;

[0053] Step S2. The pixels of the first image and the pixels of the second image are respectively matched with the pixels of the third image in grayscale, and the third image is reconstructed according to the grayscale matching result;

[0054] Step S3....

Abstract

The invention discloses a video super-resolution reconstruction method and system for a satellite camera, and the method comprises the steps: S1, amplifying resolutions of an nth frame image, an (n-1) th frame image and an (n-2) th frame image in a video according to a preset multiple, and obtaining a first image, a second image and a third image, n being greater than or equal to 3; S2, subjecting pixel points of the first image and pixel points of the second image to gray scale matching with pixel points of a third image, and recreating the third image according to a gray scale matching result; and S3, sequentially processing each frame of image in the video according to the step S1 and the step S2. According to the invention, the resolution of the video image is improved through a low-complexity algorithm.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a satellite camera-oriented video super-resolution reconstruction method and system. Background technique [0002] With the development of technologies such as new materials, electronics, optics and artificial intelligence, micro-nano satellites of tens of kilograms have been able to perform tasks that satellites of hundreds of kilograms used to undertake. After the size and weight of the satellite are reduced, in addition to greatly reducing the development cost and operating cost, the development time can also be greatly shortened, and the rocket with a small launch capacity can be effectively used for launch, which is also conducive to plan management and adapting to the needs of various tasks. To realize the miniaturization of satellites, the key lies in the effective use of high-tech, and the successful development of ultra-small, lightweight and stable payloads. T...
