Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0039]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention provides an infrared and visible image fusion method based on a mixed curvature filter. The infrared and visible image fusion method comprises the following steps: performing image decomposition on an infrared image to obtain a detail layer, a rough layer and a base layer of the infrared image; performing image decomposition on the visible image to obtain a detail layer, a rough layer and a base layer of the visible image; respectively fusing the detail layers, the rough layers and the base layers of the infrared image and the visible image to obtain a small-size layer, a large-size layer and a fused base layer; and superposing the small-size layer, the large-size layer and the fused base layer to obtain an infrared and visible light fused image. According to the method, the problem that the detail texture information is likely to lose when the infrared image and the visible image are fused by the existing fusion image processing method is solved, the detail texture information, the edge information and the structure information of a source image are reserved, and a better visual perception effect can be presented.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an infrared and visible light image fusion method based on a hybrid curvature filter. Background technique [0002] In the process of shooting the scene and the target, the infrared sensor can identify and capture the surrounding environment and the infrared band radiation information emitted by the target without being affected by the lighting conditions. The infrared image obtained by it has outstanding characteristic imaging effects, but lacks specific background Detailed information and spatial distribution information; [0003] Visible light sensors can record scene information that is consistent with human perception according to the reflection characteristics of object spectral information, have higher image resolution, and clearly present the texture and details of the target area, but cannot understand the radiation information of the target. [0004] I...
