Abstract

The invention discloses a diffusion information-based image defogging method and system under a foggy condition. The method comprises the following steps: acquiring a foggy image of a to-be-detected area; carrying out image information enhancement on the acquired foggy image by utilizing image diffusion; and outputting the processed image. The system comprises an image acquisition module, a defogging processing module and an image output module. According to the invention, image defogging is realized based on an image diffusion forming mechanism, a better defogging effect can be obtained, the cost is low, the operation is simple, and the calculation complexity is low.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to an image defogging method and system based on diffusion information under foggy conditions. Background technique [0002] Visual perception has always been one of the main perception methods for various types of unmanned systems at sea when performing tasks. Using visual images, we can obtain rich external information in a relatively concealed situation, and play an irreplaceable role in the normal operation of the system. . However, when visual technology is used, the phenomenon of sea fog will pose a serious challenge to the perception effect. In recent years, image processing tasks under foggy conditions have always been an important technical direction in the image field, and have a wide range of application prospects. [0003] The technical exploration of image dehazing can be traced back to the 1950s. At first, it was mainly to solve the problem of unclear images ...
