Problems solved by technology

[0004] The technical problem to be solved by the present invention is an image processing method, which can collect images of two different wavelengths, visible light and near-infrared, and use near-infrared to have a stronger ability to penetrate obstacles, and fuse the two images to solve the problem of In the existing technology, it is impossible to deal with the problem of obtaining a clear image in the case of low visibility, so as to improve the clarity and details of the image in the scene of low visibility, improve the clarity and contrast of the image, and improve the detail performance of the photo

Embodiment 1

[0044] To achieve the above purpose, if figure 1 As shown, the present invention provides a method for image processing, including:

[0045] S11. One or more image processing devices collect visible light images and near-infrared images of the same scene.

[0046] Embodiments of the present invention provide one or more image processing devices for collecting and processing images of two different wavelengths, that is, visible light images and near-infrared images. The image processing device can be a mobile terminal with dual cameras, one camera is used to collect visible light images and the other is used to collect near-infrared images; it can also be a camera / camera with dual lenses, or a single CCD / CMOS camera, through The method first collects visible light images, and then collects near-infrared images. The CCD / CMOS sensor can perceive near-infrared bands with a wavelength higher than 780nm, so it can collect visible light and near-infrared images. When collecting visi...

Embodiment 2

[0066] Embodiment 2 of the present invention provides a method for image processing. Through the method provided in Embodiment 2 of the present invention, the clarity and details of the image can be improved in environments with low visibility such as fog and haze, and the saturation of the image can be improved to improve user experience. Such as figure 2 shown, including the following steps:

[0067] S21. One or more image processing devices collect visible light images and near-infrared images of the same scene;

[0068] The wavelength of light covers a large range, and the wavelength of visible light that can be observed by the human eye is 390-780nm, which is only a small part of it. The CCD / CMOS sensor of the camera can also perceive the near-infrared band with a wavelength higher than 780nm, but ordinary cameras filter out the near-infrared band and only present information of visible light.

[0069] According to the diffraction of light, light with a longer wavelen...

Embodiment 3

[0086] An embodiment of the present invention provides an image processing device, and the image processing device can also be applied to an image acquisition scene and / or a video acquisition scene, such as image 3 As shown, the device includes the following structure:

[0087] A collection unit 301, configured to collect visible light images and near-infrared images of the same scene;

[0088] The acquisition unit 301 is also used to control the target field of view of the camera of the multi-mode acquisition module. The acquisition unit 301 is fixed on a three-degree-of-freedom rotary table, and the direction is controlled by a vertical axis, a vertical axis, and a horizontal axis. The three axes are respectively controlled by a precision motor. The acquisition unit 301 is fixed on a three-degree-of-freedom rotary table , where the NIR camera and visible light camera should have the same parameters as possible. The only difference is the filter. In addition, the infrared...

Abstract

The invention discloses an image processing method and apparatus. By acquiring the visible light image and a near-infrared image of the same scene, the visible light image and the near-infrared image are mapped to the same viewing angle, and the visible light image and the near-infrared image are fused to obtain the multimode image fusion. Image definition and detail in low visibility scenes can be improved, the problem that in the prior art, a clear image cannot be obtained at low visibility is solved, so that the image definition and contrast can be improved, and the shooting detail is improved.

Description

technical field [0001] The invention belongs to the field of video and image processing, and in particular relates to an image processing method and device. Background technique [0002] The role of image and video processing technology in daily production and life is becoming more and more important. However, affected by factors such as heavy fog, dense fog, dust, and haze, the images collected by ordinary cameras are not satisfactory, and there are low visibility and contrast. Low, short observation distance, loss of details and other issues. Therefore, it is of great significance to solve the above problems and improve the clarity and depth of field of videos and images, which can be used in security, monitoring and daily photography. [0003] In the prior art, for scenes with low visibility such as fog and haze, a large number of image processing calculations are required to obtain clear photos. The usual practice is to continuously shoot two images in the same scene as...
