Embodiment 1

[0056] figure 1 It is a flow chart of an image fusion method provided in Embodiment 1 of the present application.

[0057] Such as figure 1 As shown, the method includes:

[0058] S101. Obtain RGB images and IR images collected in the same scene;

[0059] In the embodiment of the present application, preferably, when the RGB image and the IR image need to be fused, the RGB image and the IR image collected in the same scene need to be acquired first.

[0060] S102. Acquire an image enhancement weight set of an RGB image;

[0061] In the embodiment of the present application, preferably, the image enhancement weight set of the RGB image includes several elements, and the number of elements is the same as the number of pixels in the RGB image, and the pixels in the RGB image are the same as the image enhancement weight set The elements of are in one-to-one correspondence, that is, for each pixel in the RGB image, there is only one element corresponding to it in the image enhanc...

Embodiment 2

[0105] Figure 5 It is a schematic structural diagram of an image fusion device provided in Embodiment 2 of the present application.

[0106] Such as Figure 5 As shown, the device includes:

[0107] An image acquisition unit 51, configured to acquire RGB images and IR images collected under the same scene;

[0108] An image enhancement weight set acquisition unit 52, configured to acquire an image enhancement weight set of an RGB image;

[0109] The image fusion unit 53 is configured to fuse the RGB image and the IR image by using the image enhancement weight set to generate a target image.

Abstract

The invention provides an image fusion method and device, and the method comprises the steps: obtaining an RGB image and an IR image, which are collected in the same scene; obtaining an image enhancement weight set of the RGB image; and carrying out the fusion of the RGB image and the IR image through the image enhancement weight set. The mode of generating a target image achieves a purpose that the defects (low imaging brightness and unclear details) of an RGB image at a single format are ironed out through the features (bright imaging and clear image details) of an IR image at a single format in a process of generating the target image through the RGB image and the IR image, thereby guaranteeing that the target image generated through the fusion of the RGB image and the IR image can effectively iron out the defects of the RGB image / IR image at the single format in the prior art.

Description

technical field [0001] The present application relates to the technical field of image fusion, in particular to an image fusion method and device. Background technique [0002] In the prior art, both color image (RGB) and infrared image (IR) technologies can only be imaged separately, and both the RGB image generated by the color image technology and the IR image generated by the infrared image technology have certain defects. [0003] For example, RGB images usually have the problem of darker imaging and unclear image details; although IR images do not have the problem of darker imaging and unclear image details, they usually have imaging that does not match the vision of the human eye, displaying unnatural question. Contents of the invention [0004] In view of this, the present application provides an image fusion method and device, through the fusion of RGB images and IR images, to solve the problem of defects in existing single-format RGB images / IR images. [0005] ...
