Sony introduced a number of surveillance camera cores with fogging and SDI support. This is technical innovation, but it is also a technological innovation based on changes in the environment. Sony's latest high-definition FCB-EV&EH series has a fog-transmitting function, and it can also obtain high-definition pictures in a foggy environment.
The haze that had not existed before was not so severe and it was also a real fog. Looking at today, especially in the north, all day is a grey day. In fact, fog and haze will have a certain impact on people's living environment. Heavy fog has a great impact on traffic. In heavy fog weather, aircraft cannot take off and land. Vehicles, ships, etc. are also prone to traffic accidents due to low visibility. The haze is often accompanied by birth. Once a large range of haze weather is formed, it can last for several days under favorable weather conditions. The weather conditions conducive to the maintenance of haze include: First, small winds are not conducive to the spread of pollutants in the horizontal direction; Second, low-altitude atmosphere stratification is stable, and near-surface prone to inversion, which is not conducive to vertical upward diffusion of pollutants, making pollutants in the Atmospheric boundary layers accumulate and visibility is low. The above conditions are necessary for the camera with the fog-transmitting function, and the SDI camera with the fog-transmitting function further enhances the sharpness of the captured video image. Uncompressed mode transmission technology, video fidelity, smooth transmission is the main advantage of SDI camera technology.
Currently known fogging algorithms can be broadly classified into two categories: one is a non-model image enhancement method, which enhances the contrast of an image and satisfies the requirements of subjective vision to achieve clarity; the other is a model-based image. The restoration method, which examines the causes of image degradation, models the degradation process, and uses reverse processing to ultimately solve the problem of image restoration.
It is also possible to develop a real-time video fogging technique based on the special requirements of video fogging. This technology is based on the principle of atmospheric optics, and distinguishes the depth of field and fog concentration in different areas of the image for filtering to obtain accurate and natural fog-through images. Real-time video fogging technology can be automatically adjusted according to changes in fog conditions to adapt to a variety of scene applications, to avoid near-view fog and excessive darkness and blurred vision; at the same time taking into account the realization of the efficiency and complexity, ensuring the entire fog Real-time and projectable. SDI cameras are fully capable of working in a hazy environment.
How to work under a variety of circumstances, especially under adverse conditions such as cloud and rain fog, SDI cameras have become the breakthrough point for many manufacturers in the bottleneck of today's high-definition technology; SDI cameras with fog-transmission function will definitely give you a clear world.
