Embodiment Construction

[0060]In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0061] At present, image fusion is simply fusion of visible light images and infrared images based on partial information. In the case of weak light intensity, if the details of the visible light image and infrared image collected by the video surveillance equipment are not clear, the fused image still cannot clearly display the details, and the image quality is poor.

[0062] In view of this, the embodiment of the present invention provides a new image processing method. Before the images are fused, exposure processing is performed on visible light images to obtain more color information, and WDR processing is performed on infrared images to obtain more detailed information. Thus...

Abstract

The invention discloses an image processing method, a camera and a computer storage medium, for solving the technical problem that details cannot be clearly displayed in image fusion in the prior art. The image processing method comprises the steps that after the exposure duration of a camera is adjusted, obtaining an exposure image shot by the camera, wherein the exposure image is a visible light image; performing wide dynamic range WDR processing on the infrared image acquired by the camera to obtain an infrared light WDR image; and carrying out image fusion on the exposure image and the WDR image according to a preset fusion algorithm to obtain a fused image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing method, a camera and a computer storage medium. Background technique [0002] Multi-channel video surveillance equipment, such as cameras, are widely used in security monitoring and so on. Usually multi-channel video surveillance equipment collects visible light images and infrared images, because the collected visible light images may have blur problems, while infrared images may affect the reflection of infrared light due to the material and color of the shooting object, and may not be able to clearly reflect out the real scene. In this regard, the fusion of visible light images and infrared images through image fusion technology can not only solve the problem of blurred visible light images, but also solve the problem of unclear infrared images, so as to obtain clearer images. [0003] At present, image fusion is simply fusion of visible light im...
