Problems solved by technology

In the process of obtaining fused images with this method, the high-frequency components of the image are suppressed, and new high-frequency components will not be added to the fused image, resulting in the image due to the influence of the polarization device on the scene radiation signal. This method may Increase the details such as the edge outline of the image are unclear, and the resolution of the image is low
[0005] Therefore, need a kind of solution that can solve the problem of low image resolution in the prior art

Embodiment Construction

[0038] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0039] In order to improve the detection and recognition ability of the fused image to the target, the fused image should not only preserve the low-frequency characteristics of the intensity image, but also highlight the high-frequency features of the target image, such as the details of the scene edge and contour in the polarization image. The conventional image fusion method is: use the polarization images of the four linear polarization directions, and directly synthesize the fusion image according to the arithmetic weighting method. In the process of obtaining the fused image by this method, the high-frequency components of the image are suppressed, and no new high-frequency components will b...

Abstract

The invention relates to a polarization image fusion method based on super-resolution image reconstruction. The polarization image fusion method based on the super-resolution image reconstruction comprises following steps: crossing a Q image, a U image, a polarization degree image and a polarization angle image in order with a cross value being less than a spacing value of a pixel unit so as to obtain an oversampling image, and performing super-resolution reconstruction on the oversampling image so as to obtain a fusion image. By employing the polarization image fusion method, radiation intensity information and detail information such as edge contours can be effectively fused, and the resolution of the fusion image can be improved.

Description

technical field [0001] The invention relates to the field of photoelectric measurement, in particular to a polarization image fusion method based on super-resolution image reconstruction. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Image fusion is to process images of the same target or scene from multiple channels, fuse redundant information and complementary information in multiple source images, highlight and strengthen useful information in the image, so that the integrated information Richer, more comprehensive and detailed description of the same scene or target, which is conducive to further analysis and understanding of images and target detection and recognition. The fused image should not only preserve the low-frequency characteristics of the intensity image, but also highlight the high-frequency...
