For the problems referred to above, the embodiment of the present application proposes a kind of recording order method, and the method is applied in the video monitoring system deploying and accelerate server, specifically see Fig. 1, is the video monitoring system schematic diagram shown in the application one exemplary embodiment.Wherein, server disposition is accelerated near monitor client equipment.
When monitor client equipment sends program request video recording request to Management Application Server, Management Application Server is region residing for monitor client equipment, recording order request is redirected on the nearest acceleration server of distance detection client device.
Accelerate server according in advance from the intellectual analysis data that memory device loads, inquire about the crucial video clip meeting recording order requirement, crucial video clip is sent to monitor client equipment.Monitor client equipment determines play content voluntarily according to the crucial video clip received.
See Fig. 2, be an embodiment flow chart of the application's recording order method, this embodiment is described from acceleration server side recording order process.
Step 201, the crucial video clip of intellectual analysis data and correspondence is loaded from memory device, described intellectual analysis packet is containing critical event triggered time point, and described crucial video clip is the video segment of the critical event in the some generation of critical event triggered time.
At present, the monitoring frontend of video monitoring system generally all has intellectual analysis function, and such as, intelligent camera is mixed line, forbidden zone and offset detect etc. by setting and obtained intellectual analysis data.See table 1, it is intellectual analysis data instance.
| Camera installation locations | West gate, garden mouth |
| Critical event triggered time point | 2015-09-1820:00:00 |
| Event | Mix line to be triggered |
| Reason | Vehicle passes through |
Table 1
Intellectual analysis data, while being sent to by monitoring video memory device to preserve, also send to memory device to preserve by monitoring frontend.Memory device carries out aftertreatment according to the intellectual analysis data received to monitoring video, such as, the video data of critical event triggered time point front and back N second is extracted from monitoring video, generate the crucial video clip that current intellectual analysis data are corresponding, namely be prepared in advance crucial video clip, loading in order to accelerating server, promoting loading velocity.
Accelerate the intellectual analysis data of server real-time synchronization memory device preservation and crucial video clip.Certainly, also can first obtain intellectual analysis data, then inquire about to memory device according to the critical event triggered time point in intellectual analysis data and load the video data of critical event triggered time point front and back N second.When synchronous data volume is larger, multiple stage can be adopted to accelerate server cluster configuration mode, improve synchronous efficiency, and then operating lag during reduction recording order.
Step 202, receives the recording order request of monitor client equipment, comprises the recording order time period in described recording order request.
As previously mentioned, when monitor client equipment sends recording order request, this recording order request is redirected to acceleration server by Management Application Server.Accelerate the time period that server can know the program request of monitor client device request from this recording order request, be called for short the recording order time period.Such as, the video recording of monitor client equipment program request 2015-09-1820:00:00 ~ 2015-09-1821:00:00.
Step 203, judges whether the critical event triggered time point in described intellectual analysis data is positioned at the described recording order time period.
Accelerate to be loaded with a large amount of intellectual analysis data in server, obtain the critical event triggered time point in intellectual analysis data, judge whether critical event triggered time point is positioned at the recording order time period of request.Such as, multiple critical event triggered time points as shown in table 2.

Table 2
Suppose, the recording order time period of monitor client device request is 2015-09-1820:00:00 ~ 2015-09-1821:00:00, then in table 2,2015-09-1820:00:00 and 2015-09-1820:30:00 fell in the recording order time period of monitor client device request.
Step 204, when described critical event triggered time point is arranged in the described recording order time period and described recording order request does not comprise concentrated instruction, crucial video clip corresponding to described critical event triggered time point is sent to described monitor client equipment.
So-called concentrated instruction refers to that monitor client device request acceleration server provides the crucial video clip through concentration for it.Concentrated instruction whether is comprised, point following two kinds of situation process according in recording order request.
When not comprising concentrated instruction in recording order request, illustrate that monitor client equipment does not need to accelerate server and carries out concentration to the crucial video clip being positioned at the recording order time period, accelerate server and directly the crucial video clip meeting the critical event triggered time point correspondence that the recording order time period requires can be sent to monitor client equipment.
Still for the video recording of monitor client equipment program request 2015-09-1820:00:00 ~ 2015-09-1821:00:00 time period, the critical event triggered time point meeting this time period is 2015-09-1820:00:00 and 2015-09-1820:30:00.Suppose, crucial video clip is put the front and back video data of 5 seconds by the critical event triggered time and is formed, then the crucial video clip that critical event triggered time point 2015-09-1820:00:00 is corresponding is the video clip of 2015-09-1819:59:55 ~ 2015-09-1820:00:05; The crucial video clip that critical event triggered time point 2015-09-1820:30:00 is corresponding is the video clip of 2015-09-1820:29:55 ~ 2015-09-1820:30:05.Accelerate server and directly above-mentioned two crucial video clips are sent to monitor client device plays.The crucial video clip that monitor client equipment interconnection is received makes interpolation processing, obtains the video recording of whole recording order time period, specifically see the description of follow-up monitor client equipment side.
When comprising concentrated instruction in recording order request, illustrate that monitor client equipment needs to accelerate server and carries out concentration to the crucial video clip being positioned at the recording order time period, now, accelerate permeated by the multiple crucial video clip being positioned at a recording order time period crucial video clip of server and send to monitor client equipment.
It should be added that, when the critical event triggered time of all intellectual analysis data loaded, point was not all positioned at the recording order time period, crucial video clip nearest for distance recording order time period start time point can be sent to monitor client equipment.Such as, if when there is not critical event triggered time point 2015-09-1820:00:00 and 2015-09-1820:30:00, crucial video clip corresponding for critical event triggered time point 2015-09-1819:50:00 can be sent to monitor client equipment, to make monitor client equipment according to the crucial video clip determination play content of the last time.
See Fig. 3, be another embodiment flow chart of the application's recording order method, this embodiment is described from monitor client equipment side recording order process.
Step 301, sends recording order request to acceleration server, comprises the recording order time period but do not comprise concentrated instruction in described recording order request.
Whether monitor client equipment can be arranged only pays close attention to critical event, when not being set to only pay close attention to critical event, represents that monitor client equipment whole process plays the video recording in the whole recording order time period; When being set to only pay close attention to critical event, represent that monitor client equipment only plays the crucial video clip being positioned at the recording order time period.
When monitor client equipment is set to only pay close attention to critical event, acceleration server is informed by the concentrated instruction be carried in recording order request, to make acceleration server make concentration to crucial video clip, specifically see the description of step 204, repeat no more.
Step 302, receives the crucial video clip that described acceleration server returns according to described recording order request.
Step 303, plays described crucial video clip by image interpolation within the described recording order time period.
From step 301, do not comprise concentrated instruction in recording order request, namely monitor client equipment is not set to only pay close attention to critical event, now, monitor client equipment in the intercropping interpolation processing of the adjacent crucial video clip received, can obtain the video recording of whole recording order time period.
Such as, video recording in monitor client equipment program request 2015-09-1820:00:00 ~ 2015-09-1821:00:00 time period, accelerate server and return two the crucial video clip 2015-09-1820:00:00 ~ 2015-09-1820:00:05 and 2015-09-1820:29:55 ~ 2015-09-1820:30:05 being positioned at the recording order time period, visible, 2015-09-1820:00:06 ~ 2015-09-1820:29:54 time period and 2015-09-1820:30:06 ~ 2015-09-1821:00:00 time period do not have critical event to occur, then monitor client equipment can on the basis of 2015-09-1820:00:05 last frame image, by image interpolation (such as, video superimpose technology) generate image in 2015-09-1820:00:06 ~ 2015-09-1820:29:54 time period, on the basis of 2015-09-1820:30:05 last frame image, generate the image in 2015-09-1820:30:06 ~ 2015-09-1821:00:00 time period by image interpolation.Thus the video recording realizing whole recording order time period 2015-09-1820:00:00 ~ 2015-09-1821:00:00 is play.
If there is no crucial video clip in the recording order time period, accelerate server layback and play the nearest crucial video clip of start time point 2015-09-1820:00:00, be assumed to be 2015-09-1819:49:55 ~ 2015-09-1819:50:05, then monitor client equipment carries out image interpolation based on the crucial video clip of 2015-09-1819:49:55 ~ 2015-09-1819:50:05, generates the video recording of 2015-09-1820:00:00 ~ 2015-09-1821:00:00.
Said process is that monitor client equipment fails to give notice the recording order process accelerated when server carries out concentration.When monitor client equipment notice acceleration server carries out concentration, when namely carrying concentrated instruction in recording order request, accelerate server and carry out concentration, permeate the multiple crucial video clip being positioned at the recording order time period a crucial video clip.Monitor client equipment is play-overed, without the need to making image interpolation process within the recording order time period after receiving the crucial video clip after concentrating.
As can be seen from foregoing description, the application carries out synchronously by accelerating server to the intellectual analysis data in memory device and crucial video clip, make monitor client equipment when recording order, without the need to across a network accessing storage device again, directly to acceleration server request nearby; And be crucial video clip by Internet Transmission, the background image do not paid close attention to for user (such as, guarded region do not have vehicle by time image) do not transmit, by monitor client equipment record a video play time make interpolation processing according to the crucial video clip received after play.Effectively can reduce the dependence to the network bandwidth by the application, monitor client equipment does not need buffer memory multitude of video data, improves program request efficiency, promotes user's program request and experiences.
