Description
Technical field
The present invention relates to a kind of imaging monitor, be specially a kind of networked fog-penetrating imaging monitor.
Background technology
Along with the development of digital imaging technology, utilize the CCD imaging technique to realize the real time monitoring of observed object has been widely used in the every field of social life and sector application.But the CCD image quality is subjected to the impact of atmospheric environment larger, and especially in the poor visibility environment such as cigarette, mist, steam, haze, the CCD image quality declines to a great extent, and greatly reduces coverage and the definition of detecting and identifying target.
The image quality of CCD is subjected to the impact of environment visibility very large, when visibility poor, on the direct impact of CCD be exactly that picture contrast descends, noise increases and causes picture quality sharply to descend, even at all can't normal imaging.
At present, the realization of CCD imaging technique has following two kinds of modes.
It is 0.4 μ m～0.78 μ m that coloured silk turns black ccd video camera service band, and its mode of operation is divided into colour imaging and black and white imaging pattern, in the situation that the stronger video camera of light works in color mode, by filter, switches and is converted into white-black pattern when light is dimmed.But in the poor visibility situation, no matter be that color mode or white-black pattern all can't solve the purpose of blur-free imaging.
CCD fog-penetration imaging system service band is 0.4 μ m～1.0 μ m, and its mode of operation is divided into former figure imaging and fog-penetrating imaging pattern.The service band of former figure imaging is 0.4 μ m～0.78 μ m, and the fog-penetrating imaging service band is 0.8 μ m～1.0 μ m.
The CCD fog-penetration imaging system mainly comprises: fog-penetrating camera, Penetrating Fog processing module, Central Control Module.
The CCD fog-penetration imaging system is whole to be formed: it is Central Control Module, Penetrating Fog processing module and fog-penetrating camera that overall structure is divided into three parts.Fog-penetrating camera is arranged on ad-hoc location corresponding to required observed object, and the Penetrating Fog processing module is arranged in the independent outdoor link box of settling of fog-penetrating camera lower end, and Central Control Module is arranged in the Surveillance center control room; Central Control Module is realized being connected by radio frequency cable or optical cable with fog-penetrating camera; Central Control Module is realized being connected by control cables or optical cable with the Penetrating Fog processing module; Fog-penetrating camera is realized being connected by netting twine or twisted-pair feeder with the Penetrating Fog processing module, due to the transmission range of netting twine or twisted-pair feeder limited (generally can not over 100 meters), the outdoor link box that therefore is provided with the Penetrating Fog processing module can only be placed in the side of fog-penetrating camera setting position.
The CCD fog-penetration imaging system, its working method is divided into three kinds, CCD works in the colour original mode in the visibility good situation, the Penetrating Fog processing module is the nucleus module of CCD fog-penetration imaging system, its effect is, by embedded microprocessor, picture signal is carried out to algorithm process, now the Penetrating Fog processing module is in off position, image is not processed, and is output as the former chart-pattern of simulation color; CCD works in the Penetrating Fog pattern when poor visibility, and the Penetrating Fog processing module works in common Penetrating Fog treatment state, and now the Penetrating Fog processing module is carried out common Penetrating Fog algorithm process to image, is output as simulation Penetrating Fog image; CCD works in and strengthens the Penetrating Fog pattern when visibility is extremely weak, and the Penetrating Fog processing module works in and strengthens the Penetrating Fog treatment state, and now the Penetrating Fog processing module strengthens the Penetrating Fog algorithm process to image, is output as simulation and strengthens the Penetrating Fog image.
The CCD fog-penetration imaging system, it controls implementation is in the visibility good situation, at central control room, send control command by the former figure button of pressing Central Control Module and by 485 control cables, be sent to the serial port circuit of Penetrating Fog processing module, by the serial port circuit of Penetrating Fog processing module, send control command and by netting twine or twisted-pair feeder, send to the filter disc control switching circuit of fog-penetrating camera, control the switching of filter disc support, now the Penetrating Fog processing module is not worked and is output as the colour original analog signal, the colour original analog signal is sent to Central Control Module by vision cable.In the poor visibility situation, the Penetrating Fog button of pressing Central Control Module sends control command and by 485 control cables, is sent to the serial port circuit of Penetrating Fog processing module, by the serial port circuit of Penetrating Fog processing module, send control command and by netting twine or twisted-pair feeder, send to the filter disc control switching circuit of fog-penetrating camera, control the switching of filter disc support, now Penetrating Fog processing module work is output as the Penetrating Fog image analoging signal, and the Penetrating Fog image analoging signal is sent to Central Control Module by vision cable.In the extremely weak situation of visibility, the enhancing Penetrating Fog button of pressing Central Control Module sends control command and by 485 control cables, is sent to the serial port circuit of Penetrating Fog processing module, by the serial port circuit of Penetrating Fog processing module, send control command and by netting twine or twisted-pair feeder, send to the filter disc control switching circuit of filtering video camera, control the switching of filter disc support, now Penetrating Fog processing module work is output as simulation and strengthens the Penetrating Fog picture signal, strengthens the Penetrating Fog image analoging signal and is sent to Central Control Module by vision cable.
In sum, no matter the CCD fog-penetration imaging system is that the output of former chart-pattern or its image of Penetrating Fog pattern is analog signal, therefore the condition of using has been subject to certain restriction, reason is that the image of output is analog signal, can not directly access in computer network, therefore this system can only be used in the connection that some specific operational environment such as scene must provide vision cable, if the connection of vision cable is not provided at some daily environment for use scenes, the CCD fog-penetration imaging system just can't normally be realized the connection of signal.
