Embodiment 1

[0026] figure 2 A process schematic diagram of an image fusion method is provided for an embodiment of the present invention, and the process includes the following steps:

[0027] S201: Receive infrared images and color images of the same scene collected at the same time.

[0028] The image fusion method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device may be an image acquisition device, a smart device such as a PC or a server.

[0029] In the embodiment of the present invention, fusion is performed on the received infrared image and color image. In order to perform image fusion accurately, the infrared image and the color image are images of the same scene collected at the same time. And in the embodiment of the present invention, in order to effectively acquire infrared images and color images, image acquisition is performed by a binocular camera. One of the binocular cameras is equipped with a filter, thr...

Embodiment 2

[0036] In order to obtain a fused image with good effect, on the basis of the above embodiments, in the embodiment of the present invention, according to the first G value, the first B value, the R value, the second G value and the second B value, determining the adjusted R value of the pixel in the infrared image includes:

[0037] determining a first sum of said R value, said second G value, and said second B value;

[0038] determining a second sum of the first G value and the first B value;

[0039] An adjusted R value of the pixel point of the infrared image is determined according to the R value, the first sum value, and the second sum value.

[0040] In order to accurately determine the adjusted R value of each pixel in the infrared image, in the embodiment of the present invention, for each pixel in the infrared image, according to the first G value, the first B value and the color of the pixel The R value, the second G value and the second B value of the pixel in th...

Embodiment 3

[0054] In order to obtain a fused image with good effect, on the basis of the above embodiments, in the embodiment of the present invention, after performing YUV domain processing on the color image and the infrared image with the R value adjusted, the fused Before the color image and the adjusted infrared image, the method also includes:

[0055] For each pixel, obtain the first Y value and the first U value of the pixel in the infrared image with the adjusted R value, and the second Y value, the second U value and V of the pixel in the color image value; according to the first Y value, the first U value, the second Y value, the second U value, and the V value, determine the adjusted Y value of the pixel in the infrared image.

[0056] In the embodiment of the present invention, after adjusting the R value of the infrared image, in order to obtain a fused image with good effect, it is necessary to adjust the brightness value of the infrared image. Therefore, after adjusting ...

Abstract

The invention discloses an image fusion method and device, equipment and a medium, which are used for solving the problems of color distortion and color cast during image fusion in the prior art. In the embodiment of the invention, the adjustment R value of the infrared image is determined according to the RGB value of the acquired infrared image and the RGB value of the color image, therefore, the influence of the color domain on image fusion is effectively considered, and the phenomena of color distortion and color cast occurring during image fusion are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image fusion method, device, equipment and medium. Background technique [0002] With the development of society, people's living standards are gradually improving, and the current requirements for image acquisition equipment are also getting higher and higher. However, the quality of color images collected by image acquisition equipment is often poor, mainly manifested in low brightness and high noise. The brightness and details of infrared images at night are much better than color images, but infrared images have disadvantages such as low pixel resolution and blurred image edges. Therefore, infrared images and color images can be fused to obtain high-quality images. [0003] In the prior art, when fusing infrared images and color images, RGB domain processing and YUV domain processing are performed on the infrared images and color images respectively, and ...
