Abstract

The invention discloses a diffusion information-based water surface target detection method and system under a foggy condition. The method comprises the steps of collecting a foggy image of a to-be-detected area; carrying out image information enhancement on the acquired foggy image by utilizing image diffusion; outputting the processed image; and performing target detection according to the output image. The system comprises an image acquisition module, a defogging processing module, an image output module and a target detection module. According to the invention, image defogging is realized based on the formation mechanism of image diffusion, a better defogging effect can be obtained, and a better target detection result can be obtained.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for detecting water surface targets under foggy conditions based on diffusion information. Background technique [0002] Visual object detection technology has always been one of the most common challenges in the field of computer vision, and has a wide range of application prospects. China has abundant marine resources. Using visual image information to monitor the sea surface is one of the important means to maintain my country's maritime security. However, the natural conditions on the sea are complex and changeable, and complex environments such as fog will seriously affect the vision of unmanned ships. Target detection effect. Therefore, it is urgent to develop a fast and effective image visual target detection system for surface unmanned ships under foggy conditions. [0003] In recent years, scholars at home and abroad have done a lot of work o...
