Problems solved by technology

The problem with this direct processing method is that it is easy to lose part of the image information and cause image distortion.
However, there are relatively few studies on removing the influence of sand and dust. The existing studies have problems such as long processing time and the need to pre-measure the distance information of some objects in the image relative to the camera instrument.
These methods are all single-purpose processing methods for dust or fog

Embodiment Construction

[0034] A method for removing the influence of dust and fog on optical pictures proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, a method for removing the influence of dust and fog on optical pictures disclosed by the present invention includes the following steps: establishing a mathematical model for pictures affected by dust or fog; calculating the overall brightness of the atmosphere; calculating the transmission coefficient; restoring a clear picture .

[0036] Such as figure 2 As shown, a mathematical model is first established for the pictures affected by dust or fog. The pictures affected by dust or fog refer to the pictures collected by the optical imaging instrument in the dust environment or foggy day. part, that is, the direct attenuation term and the atmospheric light component. The direct attenuation item means that the reflected light of the actual scene is a...

Abstract

The invention discloses a method for eliminating influence on an optical picture by dust and mist. The method comprises the following steps: establishing a picture model which is influenced by the dust and the mist; calculating integral atmospheric brightness; calculating a transmission coefficient; and recovering a clear picture. The method can eliminate the influence on optical imaging by the dust and the mist, also has two functions of eliminating dust influence and eliminating mist influence, can recover the picture influenced by the dust and the mist to the clear picture, improves the visual effect of the picture, improves the definition of the picture, causes the picture to contain rich scene information, and brings convenience for the later processing and utilization of the picture. Under a situation that the collected picture is not influenced by the dust or the dust, the definition of the image is not influenced when the method processes the image.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a method for removing the influence of dust and fog on optical pictures. Background technique [0002] With the development of computer vision technology, its application is becoming more and more extensive, and it has a wide range of applications in security monitoring, transportation and military fields. However, the image quality is relatively low in dusty or foggy weather, the color of the image is off-white, the contrast is relatively low, and the visual effect is poor, which will affect the systems that rely on optical imaging, such as outdoor monitoring systems, aerial photography systems, target Identification systems and remote sensing systems, etc. Therefore, there is an urgent need to solve the problem of dust or fog interfering with optical imaging pictures and improve image quality. [0003] At present, there are many researches on the methods of defogging...
