All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the related technology, after an event in code stream data is identified by the IPC, alarm information is sent to a management server in real time, and the management server generates an event index of the event according to the alarm information. And the subsequent user can inquire the code stream data required by the subsequent user in the storage server according to the event index. However, in the related art, if the number of IPCs accessed by the management server is large, the alarm information sent by the IPCs is frequently received, and further, the event index is frequently generated according to the alarm information, thereby consuming a large amount of processing resources of the management server.
In order to solve the technical problem, an embodiment of the present invention provides a data storage system, which may include a storage server and a management server.
The storage server is used for receiving code stream data sent by the video acquisition equipment and storing the code stream data; determining each target video frame based on an analysis result obtained by analyzing the code stream data; respectively generating event indexes corresponding to each target video frame, and reporting the generated event indexes to the management server; wherein, the code stream data includes: adding mark information aiming at a target video frame containing a preset event;
and the management server is used for receiving each event index reported by the storage server and storing each received event index.
As can be seen from the above, according to the scheme provided by the embodiment of the present invention, the video acquisition device adds the mark information to the target video frame containing the preset event in the code stream data, and sends the code stream data including the mark information to the storage server. Thus, after receiving the code stream data, the storage server can analyze the code stream data to obtain an analysis result, and determine each target video frame based on the analysis result, thereby respectively generating an event index corresponding to each target frame, and reporting each generated event index to the management server. Furthermore, the management server can receive each event index reported by the storage server and store each received event index.
Based on this, by applying the scheme provided by the embodiment of the present invention, the event index is generated after the storage server analyzes the code stream data, but is not generated according to the alarm information after the management server receives the alarm information sent by the video acquisition device in real time. Therefore, by applying the scheme provided by the embodiment of the invention, the management server does not frequently receive the alarm information, and further, the event index is not frequently generated according to the alarm information. Therefore, the consumption of processing resources of the management server can be reduced, and the bandwidth consumption caused by pushing the alarm information to the management server by the video acquisition equipment can be saved.
The storage server included in the data storage system may be a single server or a server cluster including a plurality of servers, and similarly, the management server included in the data storage system may be a single server or a server cluster including a plurality of servers.

After the IPC collects the code stream data, whether a preset event exists in each video frame in the code stream data can be identified, if so, the video frame can be determined as a target video frame, and mark information is added to the target video frame.
The preset event may be various events that need to be identified and are preset by a user, for example, whether a specific person exists in a video picture, whether a person intrudes into a set area in the video picture, whether a traffic accident exists in the video picture, and the like, and specific events are not listed one by one.
After the target video frame in the code stream data is identified and obtained and the marker information is added to the target video frame, the IPC may send the code stream data to which the marker information is added to the storage server 210, so that the storage server 210 may obtain the code stream data including the marker information added to the target video frame including the preset event.
Further, the storage server 210 may analyze the received code stream data to obtain an analysis result, and further determine each target video frame in the code stream data based on the obtained analysis result.

Optionally, in a specific implementation manner, the determining, by the storage server 210, a manner of each target video frame based on an analysis result obtained by analyzing the code stream data may include the following step 11:
step 11: the storage server 210 analyzes the code stream data to obtain each video frame; and reading the data of the preset mark bit in each video frame, and determining whether the video frame is a target video frame according to the read data.
As described above, the code stream data includes the mark information added for the target video frame including the preset event, and in this specific implementation, the video capture device may add the mark information in the preset mark bit of the frame information of the code stream data. In this way, after the storage server analyzes the code stream data to obtain each video frame, the storage server may read data of a preset flag bit of frame information of the video frame for each video frame, and determine whether the video frame is a target video frame according to whether the read data is the flag information added for the target video frame.
When the read data is the mark information added for the target video frame, the video frame can be determined to be the target video frame, otherwise, the video frame can be determined not to be the target video frame.
The specific position, the occupied byte number and the like of the preset mark bit in the frame information of the video frame are not limited, and the specific marking condition of the preset mark bit is not limited.
For example, the unmarked state may be represented by 0, and the marked state may be represented by 1, that is, 1 may be used as the mark information added for the target video frame, that is, when a certain video frame includes a preset event and is thus determined as the target video frame, the data acquisition device may set the data of the preset mark bit to 1 in the frame information of the video frame in the code stream data.
Optionally, in a specific implementation manner, the data of the preset flag bit may also indicate an event type of the preset event. For example, data 01 indicates that a traffic accident exists in the video image, data 10 indicates that a human intrusion event exists in the video image, data 11 indicates that a human a appears in the video image, and the like, and the correspondence relationship between the specific data of the preset flag bit and the event type is not limited.
In this way, when a certain video frame includes a preset event and is determined to be a target video frame, the data acquisition device may determine data corresponding to an event type of the preset event included in the video frame, and set data of a preset flag bit in frame information of the video frame in the code stream data as data corresponding to the event type of the preset event included in the video frame.
After each target video frame is determined, the storage server 210 may generate an event index corresponding to each target frame.
Optionally, in a specific implementation manner, the manner in which the storage server 210 generates the event index corresponding to each target frame respectively may include the following steps 21:
step 21: for each target video frame, the storage server 210 generates an event index corresponding to the target video frame according to the identifier of the video capture device corresponding to the target video frame and the time information of the target video frame.
In this specific implementation manner, the event index corresponding to each target video frame may include an identifier of the video capture device that captures the target video frame, for example, an Identity document (IPC ID), and time information of the target video frame, for example, a timestamp, a frame number, and the like. The time information of the target video frame may represent the capture time of the target video frame.
In this way, the video capture device that captures the corresponding event to be searched and the capture time of the corresponding event may be subsequently determined based on the generated event index, so that the user may search the video data corresponding to the corresponding time in the storage server 210 according to the event index.
Optionally, in another specific implementation manner, on the basis that the data of the preset flag bit may also represent an event type of a preset event, the storage server 210 may further be configured to:
and aiming at each video frame obtained by analysis, under the condition that the video frame is determined to be a target video frame, determining the event type of a preset event contained in the target video frame according to the data of the preset mark bit.
In this specific implementation manner, for each video frame obtained through parsing, if the storage server 210 determines that the video frame is a target video frame, the storage server 210 may determine an event type of a preset event included in the target video frame according to data of a preset flag bit of frame information of the target video frame.
Accordingly, in this specific implementation manner, the manner in which the storage server 210 generates the event index corresponding to each target frame respectively may include the following steps 22:
step 21: for each target video frame, the storage server 210 generates an event index corresponding to the target video frame according to the identifier of the video capture device corresponding to the target video frame, the time information of the target video frame, and the event type of the preset event included in the target video frame.
In this specific implementation manner, for each target video frame, an event index corresponding to the target video frame may be generated according to the identifier of the video capture device corresponding to the target video frame, the time information of the target video frame, and the type of the preset event included in the target video frame.
That is to say, in this specific implementation manner, the event index corresponding to each target video frame further includes an event type of a preset event included in the target video frame, so that the preset event of the specified type to be searched can be directly located subsequently based on the generated event index, and thus, it is further convenient for the user to search for the required video data.
After generating the event index corresponding to each target video frame, the storage server 210 may report the generated event indexes to the management server 220.
In this way, the management server 220 may receive each event index reported by the storage server 210, and store each received event index.
Based on this, the management server 220 may obtain the event index of each target video frame acquired by the video acquisition device without receiving the alarm information sent by the video acquisition device in real time and generating the event index according to the alarm information.
As can be seen from the above, with the solution provided by the embodiment of the present invention, the event index is generated after the storage server analyzes the code stream data, but is not generated according to the alarm information after the management server receives the alarm information sent by the video capture device in real time. Therefore, by applying the scheme provided by the embodiment of the invention, the management server does not frequently receive the alarm information, and further, the event index is not frequently generated according to the alarm information. Therefore, the consumption of processing resources of the management server can be reduced, and the bandwidth consumption caused by pushing the alarm information to the management server by the video acquisition equipment can be saved.
Optionally, in a specific implementation manner, the storage server 210 may be further configured to:
and converting the code stream data into video data supporting positioning playback, and storing the video data.
In this specific implementation manner, after receiving the code stream data sent by the video acquisition device, the storage server 210 may further convert the code stream data into video data supporting positioning playback, and store the video data obtained by the conversion.
The video data obtained by conversion supports positioning playback, so that the video data can be directly positioned to any time point for playing.
On the basis of this specific implementation manner, optionally, the management server 220 may further be configured to:
receiving a query request sent by user equipment, determining a target event index corresponding to the query request in the stored event indexes, and feeding back the target event index to the user equipment.
Accordingly, the storage server 210 may further be configured to:
and receiving a target event index sent by the user equipment, calling target video data corresponding to the target event index from the stored video data, and feeding the target video data back to the user equipment.
If the user needs to query the video data, the user may use the user device to obtain the target event index from the management server 220, and retrieve the video data to be queried from the storage server 210 according to the target event index.
Optionally, when the event index includes the identifier of the video capture device and the time information of the target video frame, the user may query the relevant video data from the time dimension and/or the device dimension, and therefore, the query request sent by the user device to the management server 220 may include the time parameter and/or the identifier of the video capture device, so that the user may query the video data of a certain period of time, may query the video data collected by a certain video capture device, and may also collect the video data collected by a certain video capture device at a certain period of time.
Optionally, when the event index includes an identifier of the video capture device, time information of the target video frame, and an event type of a preset event included in the target video frame, the user may query related video data from at least one of a time dimension, a device dimension, and an event type dimension, so that a query request sent by the user device to the management server 220 may include at least one type of information of a time parameter, an identifier of the video capture device, and an event type parameter, and thus, the user may query at least one type of video data among the following video data:
the video data of a certain period of time, the video data collected by a certain video collecting device, the video data containing a certain type of preset event, the video data collected by a certain video collecting device in a certain period of time, the video data containing a certain type of preset event collected by a certain video collecting device, and the video data containing a certain type of preset event collected by a certain video collecting device in a certain period of time.
Optionally, in a specific implementation manner, the storage server 210 may further store the converted video data and the event index corresponding to each generated target video frame into a cloud storage together.
Furthermore, in order to facilitate understanding of the respective roles of the storage server 210 and the management server 220 and the interaction process therebetween, as shown in fig. 3(a), a signaling interaction diagram between the storage server 210 and the management server 220 is shown. As shown in fig. 3(a), the signaling interaction process between the storage server 210 and the management server 220 may include the following steps S301-S305.
S301: the storage server 210 receives code stream data sent by the video acquisition device and stores the code stream data;
s302: the storage service 210 determines each target video frame based on an analysis result obtained by analyzing the code stream data;
s303: the storage server 210 respectively generates an event index corresponding to each target video frame;
s304: the storage server 210 reports each generated event index to the management server 220;
s305: the management server 220 receives each event index reported by the storage server 210, and stores each received event index.
Optionally, in a specific implementation, the storage server 210 may include an access module 211 and a storage module 212, and in this specific implementation, signaling interaction among the video capture device 100, the storage server 210, and the management server 220 is as shown in fig. 3 (b):
the video acquisition device 100 acquires code stream data, adds mark information to a target video frame containing a preset event in the code stream data, and sends the code stream data including the added mark information to the access module 211;
the access module 211, on one hand, analyzes and reassembles the encoded stream data to obtain video data supporting positioning playback, and on the other hand, identifies each target video frame during the process of analyzing the encoded stream data, and generates an event index corresponding to each target video frame. The access module 211 stores the video data in the storage module 212, and stores the event index in the management server 220.
The storage module 212 returns a message of successful writing after storing the video data, and the management server 220 also returns a message of successful writing after storing the event index.
If the user needs to query the video data, the event index may be obtained from the management server 220, and the video data that needs to be queried may be retrieved from the storage server 210 according to the event index.
Based on this, by applying the scheme provided by the embodiment of the present invention, the video acquisition device directly writes the mark information added for the target video frame into the corresponding video frame of the code stream data, so that the video acquisition device writes the code stream data into the storage server and also writes the added mark information into the storage server at the same time. The storage server directly acquires all the mark information written by the video acquisition equipment while analyzing the code stream data.
Therefore, on the first hand, bandwidth consumption caused by the fact that the video acquisition equipment pushes a large amount of alarm information to the management server is omitted. In the second aspect, the CPU calculation power consumed by the management server side for processing a large amount of alarm information is reduced. In the third aspect, the code stream data is analyzed without the calculation power of a newly added storage server, so that the CPU calculation power consumption of the storage server is reduced. In the fourth aspect, the code stream analysis process of the storage server is directly multiplexed to extract the marker information, and other devices do not need to be additionally arranged to extract the event marker, so that the CPU (Central processing Unit) computational power consumption of the storage server is further reduced.
Further, as shown in fig. 4, a schematic diagram of data interaction among the IPC, the storage server, the management server, and the user equipment in an embodiment of the data storage system provided by the embodiment of the present invention is provided.
