Description
Technical field
The present invention relates to a kind of video acquisition and processing system, and in particular to a kind of multichannel image acquisition processing system.
Background technology
Wireless video monitoring system, is supported the use with web camera in one, can be using wired or wireless way connection
Network, it is easy to installation and deployment, it is not necessary to which user additionally configures the equipment such as special purpose computer and collection video recording, user can using mobile phone or
Computer can receive warning message and checking monitoring video whenever and wherever possible as monitoring terminal equipment.There should be reliable and stable, economy
Practical the features such as, escorted available for fire-proof and theft-proof, safety, personnel's monitoring, remote management etc., be particularly suitable for individual, family, shop
Etc. using.Image procossing acquisition system is in industrial circle using quite varied, such as recognition of face, intelligent digital monitoring, paper
Stain analysis, multiway images splicing etc..These current widely used image collection processing systems often use special
Image procossing DSP, this kind of DSP advantage be with Video Port, PAL directly can be connected by video decoding chip
The simulation CCD camera of standard, but this kind of DSP operational capability is limited, tends not to support parallel multi-channel realtime graphic
Processing Algorithm, and the accessible CCD camera negligible amounts of single-chip.Multichannel and do not need ultra high-definition image should
With occasion, such as in multichannel face identification system, either special image procossing DSP or general multi-core DSP be often all
It is faced with awkward.The former is because performance is not enough, it is necessary to which a large amount of chips, board size, complexity, cost all accordingly increase；Afterwards
Person is then because without special video interface, when connecting multichannel pal mode simulation CCD camera, being faced with identical and asking
Topic.
The content of the invention
In order to overcome the deficiencies in the prior art, analog pal formula ccd video camera is connected for general multi-core DSP
Complexity, the invention provides a kind of multichannel image acquisition processing system, multiple simulation CCD shooting can be connected simultaneously
Head, the multiple scene images of parallel acquisition realize that many scenes in parallel are shown in real time.
To achieve the above object, the present invention provides a kind of multichannel image acquisition processing system, and it includes simulation CCD shootings
Head, filter network, video decoding chip, fpga chip, multi-core DSP unit, computer, the simulation CCD camera collection are regarded
Frequency evidence, and the filtered network of data is filtered processing, modulus is carried out by video decoding chip after the filtered processing of data
Conversion, the data transfer after multigroup video decoding chip conversion is to fpga chip, and fpga chip passes multi-channel video data signal
Computer is sent to after delivering to multi-core DSP unit, multi-core DSP cell processing data.
Further, the simulation CCD camera can set 2-12 according to the actual requirements.
Further, the simulation CCD camera is distributed in different acquisition scene.
The video data acquiring of the achievable multichannel mould CCD camera of the present invention, filtering, decoding, realize that parallel acquisition is multiple
Scene image, using DSP many nuclear properties, realizes the processing in real time of many scenes in parallel and shows.
Embodiment
The present invention provides a kind of multichannel image acquisition processing system, and it includes simulation CCD camera, filter network, regarded
Frequency decoding chip, fpga chip, multi-core DSP unit, computer, the simulation CCD camera gather video data, and by data
Filtered network is filtered processing, and analog-to-digital conversion, multigroup video solution are carried out by video decoding chip after the filtered processing of data
Data transfer after code chip conversion is to fpga chip, and multi-channel video data signal is sent to multi-core DSP unit by fpga chip,
Computer is sent to after multi-core DSP cell processing data.Wherein simulation CCD camera can set 2-12 according to the actual requirements,
Simulate CCD camera and video acquisition is carried out to many scenes, single simulation CCD camera is filtered by corresponding filter network
Reason, single filter network has corresponding video decoding chip to be changed again, and multiple video decoding chips can be by one
Fpga chip carries out reception processing vision signal, and because multi-core DSP unit has multiple cores, each DSP core can handle one
Road video data, so as to realize that multi-channel video data are shown in real time on one computer.Therefore, the achievable multichannel of the present invention
The video data acquiring of mould CCD camera, filtering, decoding, realize the multiple scene images of parallel acquisition, special using DSP multinuclear
Property, realize the processing in real time of many scenes in parallel and show.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
