Fog penetration shooting method based on binocular camera

Abstract

The invention discloses a fog penetration shooting method based on a binocular camera, and relates to the field of camera monitoring. The method comprises the following steps: (1) imaging a scene by two cameras of the binocular camera; (2) finding out identical scene points in the two cameras in an outline comparison manner, and calculating the coordinates of the points; (3) slicing the scene according to distance, and slicing the scene with the same za into one piece; (4) executing different fog penetration algorithms on slices with different distances or adopting the same fog penetration algorithm to execute different fog penetration parameters; and (5) outputting an image. According to the invention, different fog penetration algorithms are adjusted or the same fog penetration algorithm is adopted to execute different fog penetration parameters according to the distances between an object in the scene with the cameras; a close-distance scene image is relatively clear, so the fog penetration effect is small, and more original image information is maintained; the fog penetration effect in a long-distance scene is strong, so more image noise is removed to make the image be clear; and thus the entire image is relatively clear and is small in distortion during the final imaging.

Description

technical field [0001] The invention relates to the field of camera monitoring, in particular to a fog-penetrating camera method based on a binocular camera. Background technique [0002] With more and more hazy weather, the cameras used in actual security projects are also increasingly emphasizing the fog penetration function. At present, there are two main methods of fog penetration for cameras: optical fog penetration and electronic fog penetration. Optical defogging mainly uses infrared rays to better pass through tiny particles to form images to achieve the effect of fog penetration; electronic fog penetration mainly uses algorithms to process images to achieve the effect of fog penetration. [0003] Although the effect of optical fog penetration is relatively good, it needs to use high-cost fog penetration lens, and the volume of fog penetration lens is generally relatively large, so the practical application is limited. [0004] In actual engineering, the electronic...

Problems solved by technology

[0003] Although the effect of optical fog penetration is relatively good, it needs to use high-cost fog penetration lens, and the volume of fog penetration lens is generally relatively large, which limits the practical application

[0004] In actual engineering, the electronic fog penetration method is widely used, but the fog penetration effect is not ideal

Most of the current electronic fog penetration algorithms use the same strength fog penetration algorithm for the entire image to process the fog, so there is a problem: due to the effect of fog, the near-distance scene image is relatively clear, and the far-distance scene image is relatively blurred

If the fog penetration algorithm is designed according to the most blurred or relatively blurred places in the image, the relatively clear close-range scene information will be lost more; if the fog penetration algorithm is designed according to the clearest or relatively clear places in the image, the distance scene The effect of fog penetration is not good
