Problems solved by technology

Because the image will inevitably be mixed with a certain amount of noise, the gray scale and contrast are used to directly obtain the side suppression coefficient, so as to determine the side suppression network model, without considering the influence of noise on the side suppression network

Embodiment Construction

[0044] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] like figure 1 As shown, the invention provides a method for suppressing the image background of an artillery remote control weapon station, comprising the following steps:

[0046] Step 1, input image;

[0047] Step 2. Determine the long-axis scale of the anisotropic Gaussian filter according to the measurement factor describing the feature of the edge point of the image, determine the short-axis scale of the anisotropic Gaussian filter according to the local variance of the image, and use the gradient information of the image to determine the anisotropic Gaussian filter. The angle of the heterogeneous Gaussian filter;

[0048] Step 3, using the major axis scale, minor axis scale and angle of the anisotropic G...

Abstract

The invention relates to a background suppression method used for a gun-projectile remote control weapon station, and relates to the technical field of image processing. A visual bionics technology isapplied; a lateral inhibition mechanism of a visual system is introduced; according to image information, a measurement factor and a local range variance for describing edge characteristics of an image are introduced for determining long and short axis scales of an anisotropic Gaussian filter; and according to gradient information of the image, direction information of the filter is determined, so that the anisotropic Gaussian filter is constructed. The image information is associated with the determination of a lateral inhibition coefficient, so that an image information-based adaptive lateral inhibition network coefficient is determined, a conventional mode of adopting a fixed lateral inhibition coefficient template is improved, and high self-adaptability is achieved. Meanwhile, duringimage characteristic selection, the influence of a noise signal on a lateral inhibition network is considered, so that the anti-noise performance of the lateral inhibition network is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a background suppression method for remote-controlled weapon stations of artillery. Background technique [0002] In the integrated design scheme of the artillery remote control weapon station, the complex battlefield environment background, background clutter and background glare in the video images collected by the sighting and sighting system will seriously affect the detection effect of missile bullets and tank targets. Background suppression (Background suppression) technology can achieve the effect of suppressing the background and highlighting the target through the preprocessing of the image. It is an important prerequisite for target detection, especially for missile target detection. Therefore, in the integrated design scheme of the artillery remote control weapon station, the background suppression technology must be used to realize the anti-jamming function....
