Abstract
The present invention relates to a method for unified access and management of massive heterogeneous video resources. The method is characterized by using a hierarchical structure, combining hardware devices from different factories with associated SDKs and packaging the hardware devices and the SDKs into respectively separated dynamic link libraries in a bottom layer of a system; on the basis of the separated dynamic link libraries, packaging a second layer of dynamic library; dynamically loading the dynamic link libraries of different factories at the second layer and secondarily packaging video exporting and viewing functions, image processing functions, and quick playing, slow playing and backwards playing functions of a specific video for different factories; and finally providing interfaces which are in unified standard and transparent for a superior platform.
Description
Technical field
The present invention relates to field of video monitoring, be specifically related to a kind of by unified for the magnanimity isomery video resource of the different video monitoring system method accessing and manage.
Background technology
Video monitoring system safeguards one of urban safety strong instrument.Video monitoring system has the function of remote real-time video monitoring, can multiple places in simultaneously remote monitoring city, and then Timeliness coverage case, prevents crime, effectively saves police strength; The video recording of crime rear video monitoring can provide important clue to solve the case and evidence for the personnel of solving a case; Video monitoring system has deterrent effect simultaneously, has important effect to crime prevention behavior.
Can for the authoritative standard followed owing to lacking, such that video monitoring system video monitoring equipment is of a great variety, brand is various.The video compression transmission standard of the product employing of different developer and host-host protocol disunity, be difficult to compatible use each other.Adopt the product of different developer, institute to form a lot of information island.In view of resource-sharing and recycling principle, city video monitoring management system must these video surveillance networks existed compatible.Therefore, the video monitoring equipment platform setting up the compatible most of main brand of an energy is the task of top priority of current city video surveillance management system Construction.Mainly there is following problem at present:
Different vendor's equipment otherness: the manufacturer of internal video monitoring at present, security device, nearly tens of family of distributors, wherein also there is 6-7 house in the producer of large-scale, adds that the original equipment of some unit and newly added equipment producer, model just need system better compatible time inconsistent.
H.263 etc. coding and decoding video mode is various, standard disunity: front compress mode is varied, has H264, AVI, MPEG, RMVB.
Various to the demand of Video processing: need to retrieve video content, the enhancing of particular video frequency, the putting soon of particular video frequency.
Summary of the invention
The present invention is intended to plurality of devices to many video producer, various video code encoding/decoding mode, various video processing demands are integrated, secondary encapsulation, is particularly applicable to, for video synthesis service supporting platform provides background service, realize following object:
1, the unification of different manufacturers video is retrieved for examination;
2, the unified process of the video content of different video equipment;
3, the unified control of the equipment of different video producer, management;
4, the video of different video producer, equipment is downloaded, is stored.
The present invention takes following technical scheme:
The unified access of a kind of magnanimity isomery video resource and management method, is characterized in that: adopt hierachical structure, at the bottom of system, the hardware device of different manufacturers combined relevant SDK, is packaged into separately independently dynamic link library; On each independently chained library, carry out the encapsulation of second layer dynamic base, in the dynamic base of this layer of dynamic load different manufacturers, and the video of different manufacturers is retrieved for examination, the putting soon of image procossing, particular video frequency, put slowly, function of putting upside down carries out secondary encapsulation, the platform interface be finally supplied to upwards is unified standard and transparent.
The present invention adopts hierachical structure, the video equipment of different vendor, interface individual packages, unified integration have been carried out, finally define one and provide unified standard and transparent support dynamic base to upper strata magnanimity isomery Video service platform, the video compression transmission standard that the product solving different developer adopts and host-host protocol disunity, be difficult to compatible use each other, be difficult to the problem of meeting customer need.The method clear in structure, be easy to expansion, unified interface be provided, meet the requirement of the unified access of platform, unified management, substantially increase the compatibility of system.
Accompanying drawing explanation
Fig. 1 is the flow chart of the inventive method
Fig. 2 is an embody rule schematic diagram of the present invention
Embodiment
As shown in Figure 1, this method adopts hierachical structure, at the bottom of system, the hardware device of different manufacturers is combined relevant SDK, is packaged into separately independently dynamic link library.On each independently chained library, carry out the encapsulation of second layer dynamic base, in the dynamic base of this layer of dynamic load different manufacturers, and the video of different manufacturers is retrieved for examination, the putting soon of image procossing, particular video frequency, put slowly, the function such as to put upside down carries out secondary encapsulation, the platform interface be finally supplied to upwards is unified standard and transparent.For platform, retrieve for examination the video of different manufacturers, different size, separate sources, the interface called is the same, thus eliminate the otherness of magnanimity isomery video, reach resource consolidation, meet platform unified standard, realize the object of unified access, unified management.
Be the present invention's embody rule embodiment shown in Fig. 2, idiographic flow is as follows:
1 by the video of the different manufacturers such as Haikang, large China substantially retrieve for examination video, processing method is encapsulated in respective XXX_plugin plug-in unit.
2 in AVSS_CTRL.dll, by all external interfaces, carry out the difference unifying to encapsulate, eliminate bottom dynamic base interface function, such as unified video retrieves for examination interface, unified video content strengthens interface, unified video playback interface, unified video download interface etc.
3 in conjunction with platform specific service and user's request, serves more specifically for magnanimity isomery Video service platform provides.The functions such as the cradle head control of the transcoding of the interface such as providing history video to put function upside down to support platform, the interface of history video content analysis, interface that suspicious object is followed the tracks of and video, compression, specific camera head.
4 to retrieve for examination when platform exits video, the function such as inquiry time, in AVSS_CTRL.dll, call relevant interface unified release software kit resource.
Claims (1)
1. the unified access of magnanimity isomery video resource and a management method, is characterized in that: adopt hierachical structure, at the bottom of system, the hardware device of different manufacturers combined relevant SDK, is packaged into separately independently dynamic link library; On each independently chained library, carry out the encapsulation of second layer dynamic base, in the dynamic base of this layer of dynamic load different manufacturers, and the video of different manufacturers is retrieved for examination, the putting soon of image procossing, particular video frequency, put slowly, function of putting upside down carries out secondary encapsulation, the platform interface be finally supplied to upwards is unified standard and transparent.
