Electronic fog transmission technology: electronic fog transmission is to achieve the purpose of clarity by enhancing the contrast of the image and meeting the requirements of subjective vision through a nonmodel image enhancement method. It has a special image processing chip, which can automatically detect the density of the image, maintain the details of the image signal to the limit, realize color enhancement, contrast enhancement, edge enhancement, contrast enhancement, and brightness enhancement, and carry out density segmentation, deblurring, and other operations so that the camera image quality under different scenes can be significantly improved to achieve the purpose of fog penetration.
Optical fog transmission technology: optical fog transmission technology is a model-based image restoration method. It examines the causes of image degradation, models the degradation process, and adopts reverse processing to finally solve the problem of image restoration. Different wavelengths of light have different characteristics because of different wavelengths. Fog and soot affect visible light imaging, while infrared has a longer wavelength and is less affected by aerosols when propagating. It can penetrate a certain concentration of fog and soot to achieve accurate focusing, which is the basis of optical fog penetration.
At the same time, the infrared thermal imaging system has the ability to penetrate smoke, fog, dust, and snow and identify camouflage. It is not disturbed by day and night, strong light and glare, and can conduct long-distance, all-weather observation, which to a large extent makes up for the shortcomings of the traditional visible light security monitoring system. In foggy weather, the infrared thermal imaging monitoring system can penetrate the dense fog and image clarity. This advantage is far more prominent than ordinary CCD monitoring, which is suitable for monitoring areas with more water mist in coastal ports.
Thermal imaging can work day and night in complete darkness or bright sunlight, through smoke, dust, and even mist, to protect ship cargo from dangers and threats, such as floating debris, rocks, ice, land, abutments, and other ships.
