Problems solved by technology
However, using temporal denoising may introduce information that does not belong to the frame image, resulting in ghosting
However, the use of spatial and frequency domain denoising may cause some details of the image to be distorted.
The denoising method of deep learning is difficult to grasp due to its working principle and low robustness, and it is difficult to process infrared images acquired in different scenes

The invention provides an infrared image cross grain removal method, an infrared image cross grain removal device and fixed infrared imaging equipment. The method comprises the following steps: acquiring a current frame of infrared image and a frame number corresponding to the current frame of infrared image; when the frame number is not greater than a preset time sequence reference frame number, determining a time sequence coding sequence, and updating a row mean value information reference queue; and when the frame number is greater than a preset time sequence reference frame number, updating a row mean value information reference queue, and processing the current frame of infrared image by using the updated row mean value information reference queue and the time sequence coding sequence to obtain an infrared image after cross grain removal. According to the method, the cross grain noise characteristics of multiple frames of infrared images continuously obtained under the same visual angle are considered, time sequence information such as row mean value information of other multiple frames of infrared images before the current frame of infrared image is utilized, space information such as information of different row pixel points in the same frame of infrared image is utilized, and the cross grain noise characteristics of the multiple frames of infrared images continuously obtained under the same visual angle are obtained. And flashing horizontal stripe noise in the infrared image is removed.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for removing horizontal stripes in an infrared image, and a fixed infrared imaging device. Background technique [0002] In recent years, production medium leakage accidents have occurred frequently in the chemical production field, resulting in explosions, fires and other consequences, seriously endangering the safety of people's lives and property. Therefore, it is increasingly urgent to promote and implement industrial safety monitoring technology in the field of chemical production. [0003] Monitoring medium gas leaks using infrared imaging equipment is one of the most advanced methods. Compared with the air in the environment, most of the medium gases have obvious characteristics in the infrared band. When monitoring production pipelines with wide-spectrum infrared imaging equipment, once a gas mass leak occurs, the processed infrared image ca...
