CCD fog-penetration imaging system and control method

Abstract

A CCD fog-penetration imaging system and control method thereof belongs to the technical field of image monitoring apparatus. The CCD fog-penetration imaging system includes a control module and a group of image processing modules which are communicatively connected through a 485 serial port. The image processing module is provided with an image collecting module that collects the image signals. One path of the image signals collected by the image collecting module directly outputs the original pattern and the other path is input to a processor for treatment. The processor is connected with asetting image display module to output the processed image signal. Aiming at the core component performing image optimization process, the invention establishes a new physical model on the basis of high-speed processing and stable hardware and absorbs the advantages of image contrast enhancement algorithm and algorithm of atmosphere physical model so as to innovatively disclose two fog-penetrationimaging physical models of ordinary fog-penetration and enhanced fog-penetration. The invention performs further optimization to the primary filter fog-penetration image so as to reach 1.6 to 2 timesof fog-penetrate capacity, thus, it is able to satisfy the requirement of fog-penetration image definition in actual application.

Description

technical field [0001] The invention belongs to the technical field of image monitoring equipment, and in particular relates to a CCD fog-penetrating imaging system for detecting and identifying images under special meteorological conditions and a control method thereof. Background technique [0002] CCD is an important device in a video surveillance system, but due to its characteristic of sensing visible light (spectral range 0.4-0.75μm), the distance to detect and identify targets under some special weather conditions (such as fog, haze, etc.) is greatly reduced. my country has a vast territory, and foggy days often appear in autumn, winter and winter and spring, which brings great challenges to video observation of many industries, such as inland river, ocean shipping, road and railway transportation, port operations, forest fire prevention, and airport and dock operations. Difficulties. [0003] Solving the imaging problem of CCD in foggy weather is not only an urgent r...
