Embodiment
Basic thought of the present invention is: through video identification technology video is discerned; The various information that identify are carried out mark through formatted language; Simultaneously can be through optimizing and the optimization of manual intervention module realization to discerning; Based on database or other structured way information storage, structural markup, various value-added services are provided then.
Need to prove that video identification technology is through designing certain computerized algorithm, the characteristic that analysis from video, extraction and video are individual, thus judge whether to meet some rule, whether belong to the situation that some need be handled, and remind.
At present the data owner taken of camera will comprise: people, car, flow of the people, vehicle flowrate, crowd such as converge at information, and these data technically can be identified.
The COS that mainly can provide at present comprises:
Video identification service: identify specific object, compare like people's face, car plate and photo etc.;
Video analysis service: provide circumference intrusion detection, object of which movement monitoring, flow of the people, vehicle flowrate, PTZ (Pan/Tilt/Zoom) from services such as motion trackings;
Video improvement service: the night vision image enhancement process is provided, functions such as image frame systems stabilisation.
The embodiment of the invention has proposed a kind of method that provides value added service based on video identification technology, and is as shown in Figure 1, and this method comprises:
Step 101: video data is discerned;
Here, can also be further the identification of video data be optimized, and/or, identifying is controlled or recognition result is made amendment according to user's operation, to improve recognition accuracy.
Need to prove that said video data can be the video data of real-time or off-line, concrete video format is not limit, and when video content is realized identification, can identify according to preset requirement: car, people, condition information.Go out information such as vehicle color, vehicle, car plate for vehicle identification; Identify the information of bicycle, electric motor car, motorcycle; The people identifies information such as height, men and women, clothing; Information such as condition information identifies crowd massing, blocks up, traffic accident.
Step 102: zhang this mode with the format mark is stored recognition result.
For example, can information of vehicles be described as with formatted language:
Time, camera, video location, place, vehicle model, car plate, vehicle color, the speed of a motor vehicle, track, place, have or not in violation of rules and regulations
Can personal information be described as with formatted language:
Time, camera, video location, place, men and women, height, clothes situation, trousers situation, cap situation, speed, hand-held article situation
Can condition information be described as with formatted language:

Need to prove that the information that can select database will format mark is stored.
Step 103: following one or more services are provided: retrieval service, the service of saving storage space, information service fast based on said recognition result.
Concrete, said provide quick retrieval service can for: in database, retrieve (as carrying out the SQL retrieval); Provide the user to watch result for retrieval.
As shown in Figure 2, a kind of flow process of quick retrieval service that provides of embodiment comprises:
The input inquiry condition;
Searching database;
According to result for retrieval, directly navigate to associated video, provide the user to watch result for retrieval.
For example, in the public security officer need retrieve sometime section, in a certain zone; The automobile of certain model of escaping; So that the location suspect, then, just can locate concrete video image easily through zhang originally carrying out the retrieval of SQL to what store format mark in the database into; Police can direct viewing, to confirm and to differentiate.Simultaneously, also can easily realize continuous-query,, be convenient to police and trace to confirm its traffic route to this vehicle.
Concrete, said provide save the storage space service can for: deletion or only storage satisfy the recognition result of pre-conditioned video content.For example, in the time of late-late, in the absence of personnel, vehicle; Just do not have to delete the video of this time period under the situation of information, to save the space; Also can take the video content of key point is noted with the photo mode, so also can save storage space in a large number.
As shown in Figure 3, a kind of flow process of saving the storage space service that provides of embodiment comprises:
According to canned data, preserve the picture that comprises information;
After storing said picture, increase search records;
The deletion original video data.
Concrete, information service comprises that mainly information provides service and information to trigger service, in other words; Said provide information service can for: recognition result is offered preset service; And/or, when recognition result satisfies trigger condition, carry out corresponding operating according to the preset trigger logic.For example, can be with the information that identifies as information source, offer such as self-navigation; Vehicle such as dredges at service, the triggering logic also can be set, when the information that identifies satisfies trigger condition; Just carry out the processing logic that triggers in the logic, provide such as services such as warning, warning, interlocks.
As shown in Figure 4, a kind of flow process of information service that provides of embodiment comprises:
Formulation information trigger policy;
Load trigger policy;
Satisfy trigger condition, carry out associative operation according to trigger policy.
Need to prove that the present invention can also be optimized the relevant parameter of video acquisition, and/or, according to user's operation the video acquisition process is controlled.
The embodiment of the invention also correspondingly proposes a kind of system that provides value added service based on video identification technology, and this system comprises: pre-processing module and application module; Wherein,
Said pre-processing module is used for video data is discerned, and stores recognition result with zhang this mode of format mark;
Said application module is used for based on the recognition result of pre-processing module storage following one or more services being provided: retrieval service, the service of saving storage space, information service fast.
Optional, this system also comprises optimal module,
Said optimal module is used for the recognition result of pre-processing module is optimized, and to promote recognition accuracy, for example, in order to promote the image recognition precision, can be optimized according to background, light and shade, the weather conditions of camera.
This system also comprises the manual intervention module,
Said manual intervention module is used to realize mutual with the user, identifying is controlled or recognition result is made amendment according to user's operation, to reach the purpose that system optimizes automatically again, promotes recognition accuracy.For example, find some objects to be discerned when inaccurate the effect that can correct identification as operating personnel.
This system also comprises video acquisition module,
Said video acquisition module is used to gather video data and supplies pre-processing module identification;
Said optimal module also is used for video acquisition module is optimized;
Said manual intervention module also is used for according to user's operation video acquisition module being controlled.
Need to prove, store recognition result with the text mode of format mark and promptly adopt structuring identifiable language to describe the various content informations of pre-processing module identification.For example, pre-processing module can be discerned the car in the video content, people, condition information, for vehicle, identifies information such as vehicle color, vehicle, car plate, and the information that identifies bicycle, electric motor car, motorcycle; For the people, identify information such as height, men and women, clothing; In addition, can also identify crowd massing, block up, status information such as traffic accident.Here, pre-processing module can be stored the information that identifies with database mode, to offer application module.
The main interface of said system comprises:
