In this embodiment, when the target multimedia information is a picture, the target searching method may search the target multimedia information through the main domain, and when the target multimedia information is a video, the target searching method may search the target multimedia information from the storage domain set through the encoding information included in the obtaining instruction. That is, when the target multimedia information is a picture, the acquisition instruction may be sent to the home domain, and the home domain searches for the target multimedia information. When the target multimedia information is a video, a target storage domain for storing the target multimedia information can be determined in the storage domain set according to the encoding information included in the acquisition instruction, and the target multimedia information can be directly searched from the target storage domain.
In an exemplary embodiment, finding a target storage domain for storing the target multimedia information from the storage domain set by using the target finding method includes: under the condition that the target searching mode is determined to be that the target multimedia information is searched through the main domain, the obtaining instruction is sent to the main domain to indicate the main domain to determine target structural information which is included in the obtaining instruction and used for identifying a target object; acquiring multimedia identification information including the target object, which is returned by the main domain based on the target structured information, wherein the multimedia identification information is data which is connected with the main domain and is pre-routed to the main domain by sub-domains; determining target multimedia identification information from the multimedia identification information based on the received confirmation instruction; determining the target storage domain based on the target multimedia identification information. In this embodiment, the storage domain set may include a master domain and a slave domain, where the master domain is connected to the service platform and may receive an acquisition instruction sent by the service platform. The master domain is connected with the slave domain, and both the master domain and the slave domain can be connected with the device and store the multimedia information generated by the device. After the device generates the multimedia information, the device can also analyze the multimedia information to obtain the structural information of the multimedia information.

The main domain determines a target storage domain according to the target multimedia identification information.
In one exemplary embodiment, determining the target storage domain based on the target multimedia identifying information comprises: sending a relative address included in the target multimedia identification information to the home domain to indicate the home domain to return an actual address based on the relative address; determining the target storage domain based on the real address. In this embodiment, after the image is stored in the local domain as part of the structured message generated by the front-end card interface device, its storage address is converged to the main domain as part of the structured message, and its basic composition of the storage address is (domain ID, intra-domain storage address). Considering that a machine room moves, a server updates and other possible situations can occur in the future, a storage address obtained after a picture is stored should not carry solidified information such as an IP and a port, because the information may fail in the near future, the picture address information carried in the structured message is a relative address, and as long as the logical architecture of a domain storing the picture is not changed, the future can be reminded regardless of changes of physical hardware. After the service platform acquires the structured message (corresponding to the target multimedia identification information), a request is sent to a picture access gateway of a main domain by using a relative storage address of a picture, the picture access gateway receives a relative address, the relative address can be understood only by the picture access gateway, the picture access gateway analyzes the address, a 302 redirection of an http protocol is returned to a requesting party (corresponding to the service platform), the request is redirected to a correct storage address (namely an actual address) in a correct domain, the nearby access of the picture is realized, the service platform only needs to access the picture access gateway of the main domain, the actual storage position of the picture is not perceived in advance, and the unified access of the picture is realized.
In an exemplary embodiment, finding a target storage domain for storing the target multimedia information from the storage domain set by using the target finding method includes: under the condition that the target searching mode is determined to be that the target multimedia information is searched from the storage domain set through the coding information included in the acquisition instruction, determining first coding information included in the acquisition instruction, wherein the first coding information is used for indicating target equipment for generating the target multimedia information; and determining a storage domain for storing the multimedia information generated by the target equipment, and determining the determined storage domain as the target storage domain. In this embodiment, when the type of the target multimedia information is a video, that is, when the target search mode is to search the target multimedia information from the storage domain set by using the encoding information included in the acquisition instruction, the first encoding information included in the acquisition instruction is determined, the storage domain for storing the multimedia information generated by the target device is determined according to the first encoding information, and the determined storage domain is determined as the target storage domain. When the first device generates video data, the attribute of the video data comprises the device to which the first device belongs and the coding channel to which the first device belongs, a segment of video data can be uniquely identified through (coding channel ID, collection time period), one coding channel is selected on a user interface, a time period is calibrated, video can be played back, and the domain of the device is not sensed, so that the unified access of the video data is realized. The first encoding information may include information such as a device ID and an encoding channel.
In one exemplary embodiment, retrieving the target multimedia information from the target storage domain comprises: determining a target time period included in the acquisition instruction; and acquiring the target multimedia information in the target time period, wherein the target multimedia information is included in first multimedia information, and the first multimedia information is information which is stored in the target storage domain and generated by the target equipment. In this embodiment, the obtaining instruction may further include a target time period, that is, the user may determine a target storage domain in the stored multimedia information according to the coding information and obtain the target multimedia information in the target storage domain according to the target time period, where the coding information of the data device and the target time period are in the service platform.
In one exemplary embodiment, the method further comprises: and sending a target processing task to the main domain to instruct the main domain to determine a first storage domain corresponding to second coding information included in the target processing task, and sending the target processing task to the first storage domain to instruct the first storage domain to perform target processing on the multimedia information stored in the first storage domain based on the target processing task, so as to obtain structured data of the multimedia information stored in the first storage domain. In this embodiment, the target processing task may be an intelligent parsing task, for example, a service platform needs to perform intelligent parsing on a video or a picture in a certain coding channel or a bayonet channel (the intelligent parsing service obtains more detailed structured data by pulling video or picture data of one channel and performing secondary fine analysis on the video and the picture), and only needs to issue the intelligent parsing task of the specified channel to an intelligent parsing scheduling center of a main domain, without considering which domain the channel is in. The intelligent analysis scheduling center of the main domain determines the domain to which the channel belongs according to the attribute of the channel, the intelligent analysis task of the channel is scheduled to the intelligent analysis service of the domain, the intelligent analysis service is accessed to the service from the equipment of the domain, or the video or picture data in the storage pool is analyzed, and the more fine structured data obtained by analysis is gathered to the big data storage pool of the main domain by the routing service, so that the nearby processing of intelligent analysis is realized, and the transmission of large-flow unstructured data of cross-domain is avoided.
In an exemplary embodiment, before receiving an acquisition instruction for instructing acquisition of target multimedia information and determining a target type of the target multimedia information, the method further comprises: acquiring identification information of a first device connected to a target platform; determining a second storage domain for storing multimedia information generated by the first device based on the identification information; and sending the identification information of the second storage domain to the first equipment so as to instruct the first equipment to store the multimedia information generated by the first equipment into the second storage domain. In this embodiment, the first device may be hardware of a standalone, tangible front-end internet of things aware device, and the first device mainly includes a "video coding device" and a "bayonet picture device". The video coding device mainly comprises a camera and a corresponding coding module, wherein the collected video image data is converted into a video digital signal through the coding module and is transmitted to other network nodes (such as a video server) through a network. The bayonet picture equipment comprises a camera, a corresponding intelligent analysis module and a picture coding module, wherein the camera takes pictures when capturing target objects (such as vehicles and people), the pictures are coded by the picture coding module to generate digital pictures, and the intelligent analysis module performs preliminary analysis on the pictures to generate some structured information (such as vehicle types, vehicle colors, human facial features and the like to form one or more readable text information which is expressed in the form of one or more records of a two-dimensional table). The service platform can endow the accessed front-end Internet of things sensing equipment with a unique ID (corresponding to the identification information), so that the equipment can be managed conveniently through the ID.
In the above embodiments, in the hardware configuration of many devices, more than one video camera or one bayonet camera may be included in a single device. For example, in some video encoding devices, multiple cameras may be used to capture images facing different directions at the same time, and multiple digital video streams can be generated at the same time through encoding. Therefore, a unit capable of generating one digital video stream may be referred to as a video encoding channel, and a video encoding apparatus capable of simultaneously generating a plurality of digital video streams may be referred to as a multi-channel apparatus. Similarly, a unit for capturing photos and generating structural information in a fixed visual area is called a bayonet picture channel, and bayonet picture equipment capable of capturing photos and generating structural information in a plurality of fixed visual areas is called multi-channel bayonet picture equipment. The service platform can endow each channel contained in the accessed front-end Internet of things sensing equipment with a unique ID, so that the channels are conveniently managed through the IDs, and the channel is the minimum unit of the front end capable of being managed by the service platform. That is, the first device may also be each channel corresponding to a multi-channel device.
In the above embodiment, when a device is added to the service platform, a domain (i.e., a storage domain) may be selected according to the physical location of the device, and each domain is identified by a globally unique domain ID. Meanwhile, the near storage and access of video data and picture data are realized, the bandwidth pressure among multiple domains is reduced, and the low delay of video picture streams is ensured.
In the above embodiment, the multimedia information refers to the sensing information from the real physical world, which is collected and generated by the front-end internet of things sensing device (corresponding to the first device). The multimedia information mainly comprises audio and video image data generated by a video coding device, picture (photo) data generated by a bayonet picture device and structured data generated by primary analysis of the picture (data describing a target object in the picture, such as human face characteristics, a vehicle type, a license plate number, a vehicle brand and the like). In the monitoring system, an intelligent analysis service may be further included, which performs further fine analysis (secondary analysis) on the video image data and the picture data generated by the front end to generate finer structured data (for example, on the basis of the front end structured data, it is analyzed whether a driver in the vehicle wears a seat belt or not, whether the driver looks at a mobile phone or not, and the like). Generally, multimedia information can be divided into unstructured data (videos and pictures, which are characterized by large data volume and low value density) and structured data (important information for describing features of targets (vehicles, people and the like) in the unstructured data, which are characterized by small data volume and high value density, and which need to be gathered in a pool for query and analysis).
In the above embodiment, the Service platform may be a SaaS (Software as a Service) Service platform. In a cloud architecture, one storage domain is a fully functional PaaS (Platform as a Service) cluster, and has capabilities of front-end IoT (The Internet of Things) device access, data storage, transmission, analysis, sharing and The like, and provides an interface to provide various Service capabilities based on data for an upper Service Platform. In physical deployment, one storage domain may be a data center or a group of racks, and the two storage domains may be separated by a long distance or a short distance, which is relatively flexible.
In the above embodiment, before the service platform acquires the instruction, the service platform may first acquire the identification information of the first device, determine, according to the identification information, the first storage domain in which the multimedia information generated by the first device is stored, and send the identification information of the first storage domain to the first device, where the first device may store the generated multimedia information in the first storage domain according to the identification information of the first storage domain.
The following describes a multimedia information acquisition method with reference to specific embodiments:
fig. 3 is a schematic diagram of an operation architecture of a multimedia information obtaining method according to an embodiment of the present invention, as shown in fig. 3: the architecture comprises a main domain and all sub-domains, wherein video data and picture data generated by front-end equipment which is respectively responsible for access are all stored in the local domain nearby. The attribute of the video data comprises the device to which the video data belongs and the coding channel to which the video data belongs in the device to which the video data belongs, a section of video data can be uniquely identified through (the coding channel ID and the collection time period), a coding channel is selected on a user interface, a time period is calibrated, a video can be played back, and the domain of the device is not sensed, so that the unified access of the video data is realized; and the picture is a part of the structured message generated by the front-end card interface device, and is stored in the local domain, the storage address of the picture is converged to the central main domain as a part of the structured message, and the basic composition of the storage address is (domain ID, intra-domain storage address). Considering that a machine room moves, a server updates and other possible situations can occur in the future, a storage address obtained after a picture is stored should not carry solidified information such as an IP and a port, because the information may fail in the near future, the picture address information carried in the structured message is a relative address, and as long as the logical architecture of a domain storing the picture is not changed, the future can be reminded regardless of changes of physical hardware. After the SaaS service platform takes the structured message, the SaaS service platform requests a picture access gateway of a main domain by using a relative storage address of the picture, the picture access gateway receives a relative address, the relative address can be understood only by the picture access gateway, the picture access gateway analyzes the address, a 302 redirection of an http protocol is returned to a requesting party, and the request is redirected to a correct storage address in a correct domain, so that the nearby access of the picture is realized.
The SaaS service platform needs to perform intelligent analysis of videos or pictures for a certain coding channel or bayonet channel (the intelligent analysis service obtains more detailed structured data by pulling video or picture data of one channel and performing secondary fine analysis on the videos and pictures), and only needs to issue an intelligent analysis task of the specified channel to an intelligent analysis scheduling center of a main domain without considering which domain the channel is in. The intelligent analysis scheduling center of the main domain determines the domain to which the channel belongs according to the attribute of the channel, the intelligent analysis task of the channel is scheduled to the intelligent analysis service of the domain, the intelligent analysis service is accessed to the service from the equipment of the domain, or the video or picture data in the storage pool is analyzed, and the more fine structured data obtained by analysis is gathered to the big data storage pool of the main domain by the routing service, so that the nearby processing of intelligent analysis is realized, and the transmission of large-flow unstructured data of cross-domain is avoided.
The quantity of a piece of structured information is about 1K to 2K, compared with the data quantity of video data and picture data, the quantity of the structured data is small, cross-domain transmission cannot form large flow pressure on a network, and if the structured data are not gathered, data isolated islands can be formed among domains, so that various big data analysis services such as similar control, face clustering, image searching and the like cannot be supported.
The message routing service is deployed in each sub-domain and the main domain, the storage of the pictures is completed in the sub-domains, after the addresses of the pictures are written into the structured messages (the step is not needed if the structured messages of the pictures do not exist), the messages are routed to the main domain by the message routing service of the local domain, and finally the main domain is responsible for storing the structured data of the global domain into the large data storage pool. The SaaS service platform can complete various big data analysis, query and control services based on universe converged data only by accessing the main domain.
From the perspective of the SaaS service platform, although video data is distributed in each domain, how to access the data can be determined by encoding the (channel ID, belonging domain ID) attribute of the channel, and the video storage pools physically distributed in each domain logically form a unified virtual video storage pool. The SaaS service platform can plan storage space for all channels uniformly, configure storage life cycle, issue video recording plans and the like without concerning which domain the channel is in.
For structured data and picture data, the SaaS service platform only needs to access a large data storage pool of a main domain and a picture access gateway, and finally the picture access gateway helps to find the actual position of the picture. The SaaS service platform can uniformly configure the life cycle of the pictures, the storage life cycle of the large data storage pool and other related parameters.
