Description
Technical field
The invention belongs to the opto-electronic conversion imaging field, be specifically related to a kind of high-definition laser Penetrating Fog night vision evidence-obtaining system.
Background technology
Along with expanding economy, the vehicle on the road is more and more, and in order to strengthen the monitoring of road, the urban road monitor system plays an important role in the public security prevention and control.Urban road is the basic framework in city, says in a sense, and the urban road monitor network is exactly the skeleton of urban public security supervisory control system.Main force as control of traffic and road, the traffic police has born system's construction such as urban highway traffic TV monitoring and controlling, the illegal monitoring candid photograph of automobile traffic, intelligent bayonet socket, the monitoring range of these three systems all is car lane, monitored object all is motor vehicles, be the important component part of urban road monitor network system, to making up urban public security prevention and control network system very important effect arranged.
Yet, three deficiencies below the existing road camera ubiquity: though 1, prior camera all has laser illumination system, the adjustable range of these laser aids is too small; 2, do not have the multispectral selection switching device shifter of many colour filters (4 colour filter), can not be simultaneously effectively at taking under different weather such as daytime, night, dense fog laser photo and the lighting condition; 3, the optimizational function that does not have picture particularly at the weather of dense fog, can not be carried out effective image rectification optimization process for the picture that photographs.
If can solve the above problems, further every function of optimizing supervisory control system, expanding it, not only can reduce its construction and maintenance cost, and technical support can be provided for the detection of all kinds of cases such as traffic, public security, improve level and the efficient of public security organ's law enforcement greatly.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, a kind of high-definition laser Penetrating Fog night vision evidence-obtaining system is provided, solved the little problem of existing system laser angle of regulation range, realized under different weather and lighting condition, by switching 4 colour filters, realize multispectral imaging down, obtain the more function of picture rich in detail.
In order to address the above problem, the present invention is by the following technical solutions: high-definition laser Penetrating Fog night vision evidence-obtaining system, it is characterized in that, comprise camera head and laser aid, described camera head comprises microprocessor, focusing module, colour filter handover module, ROM, display module, DSP module, picture quality judgement correction module, and described focusing module, colour filter handover module, ROM, display module, DSP module and picture quality judge that correcting module is connected respectively on the microprocessor; Described laser aid comprises laser controlling chip and angle adjustment module, and described angle adjustment module is connected with the laser controlling chip; Described laser controlling chip is connected by synchronizer with microprocessor.
Further, be provided with single-chip microcomputer and intelligent Penetrating Fog program storage in the described DSP module, and described intelligent Penetrating Fog program storage is connected with single-chip microcomputer.
Further, comprise following four kinds of colour filters in the described colour filter handover module at least: blue glass colour filter, all-pass colour filter, 800nmlp colour filter and 850nmlp colour filter.
The invention has the beneficial effects as follows: the present invention is directed to the little problem of laser angle of regulation range, be provided with special angular adjustment module, increased the angle of regulation range of laser greatly, simultaneously, for at different weather conditions, be provided with the special colour filter handover module of a cover, make and under different weather conditions and illumination condition, can both obtain distinct image, in addition, in order to tackle the capture problem under the foggy weather, the Penetrating Fog program storage that in single-chip microcomputer, arranges specially also, cooperate colour filter handover module and focusing module, further optimize the quality of capture under the foggy weather, be road monitoring and traffic, the detection of all kinds of cases such as public security provides strong technical support.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples:
Fig. 1 is system configuration theory diagram of the present invention.
Embodiment
As shown in Figure 1, high-definition laser Penetrating Fog night vision evidence-obtaining system of the present invention, it comprises camera head and laser aid, described camera head comprises microprocessor, focusing module, colour filter handover module, ROM, display module, DSP module, picture quality judgement correction module, and described focusing module, colour filter handover module, ROM, display module, DSP module and picture quality judge that correcting module is connected respectively on the microprocessor; Described laser aid comprises laser controlling chip and angle adjustment module, and described angle adjustment module is connected with the laser controlling chip; Described laser controlling chip is connected by synchronizer with microprocessor, and described synchronizer is used for guaranteeing the consistency of laser facula and optics fog filter focal length.
Further, be provided with single-chip microcomputer and intelligent Penetrating Fog program storage in the described DSP module, and described intelligent Penetrating Fog program storage is connected with single-chip microcomputer.
Further, at least comprise following four kinds of colour filters in the described colour filter handover module: blue glass colour filter, all-pass colour filter, 800nmlp colour filter and 850nmlp colour filter, can under different weather and time situation, according to the difference of wavelength, select suitable colour filter.
During use, make laser aid and camera head synchronous by synchronizer, video shooting and picture that the camera meeting is real-time, at this moment, picture quality judges that correcting module can carry out the quality judgement to picture shot, do not meet standard if judge photographic quality, the colour filter handover module colour filter that can automatically switch, till being transformed into satisfactory colour filter, moreover, focusing module can be adjusted the focal length of camera lens, meanwhile, the angle adjustment module also can be selected suitable angle, finally makes camera head obtain picture clearly.
When running into foggy weather, except above-mentioned method of adjustment, the functional Penetrating Fog program in the DSP module also can start, and realizes the further optimization to photographic images, has strengthened the definition of photographic images under the foggy weather greatly.
The above is preferred implementation of the present invention, for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, and these improvements and modifications also are regarded as protection scope of the present invention.
