Abstract
The invention provides a method for effectively reducing the volume of a video file through a dynamic area capture technology and relates to a surveillance video storage technology. Acquisition and encoding work of video data is distinguished according to a mode of dynamic data and static data, and mutually independent encoding parameters are set for corresponding attributes of two different data for respective operation. According to the invention, the data amount of video acquisition can be substantially reduced, and the volume of a high-definition video is reduced.
Description
Technical field
The present invention relates to monitoring video Techniques of preserving, more particularly, to a kind of effectively minimizing by dynamic area capturing technology are regarded
The method of frequency file volume.
Background technology
With the progressively promotion and application of Video Supervision Technique, the information transfer that multitude of video monitoring device is collected and
Storage problem has had become as the huge obstacle of restriction the sector development.Limited broadband resource, the backup requirements of magnanimity are carried
Come is all high cost pressure.
Although the development of video coding technique similarly achieves huge progress, particularly the making of h264/h265 technology
With greatly alleviating the related pressure in video storage.But when needing in the face of HD video demand and large-range monitoring, this
The change that a little technology are brought is still hard to carry on.
Content of the invention
For solving above technical problem, the data volume of video acquisition is greatly lowered, reduces HD video volume, particularly
For situation that is long-time, continuing video data acquiring on a large scale, the present invention proposes one kind and passes through dynamic area capturing technology
The method effectively reducing video file volume.
The collection of video data, coding work, the mode according to dynamic data and static data to be carried out area by this method
Point, and set separate coding parameter for the respective attributes of two kinds of different pieces of informations, operate respectively.
Concretely comprise the following steps:
Step 1: monitoring video flow is automatically divided into by more than one according to user's setting or dynamic area technology of identification different
Coding region.
Step 2: setting background area scope, set according to user and select minimum code level, or simply with Background
The mode of piece is substituted, to reach minimum resource occupation amount.
Step 3: the secondary coding region of setting, for this region, corresponding coding parameter is set, by reduce crucial number of frames,
Reduce the modes such as frame rate to weaken the bandwagon effect in this region, thus reducing the purpose of resource occupation.
Step 4: setting main code region, set the coding parameter of different time sections for this region, such as: busier
Time period in the higher coding quality of setting, and dynamic image is less or reduces coding quality in blank phase, by dynamic
The mode reconciled flexibly to grasp the output of Video coding.
Step 5: arrive the related setting of step 4 according to step 2, start independent video coding process, then by data according to
Certain format requires to be saved among unified file.
Step 6: identify fileinfo using corresponding player decoding plug-in, according to partition information in broadcast interface
In corresponding position fill the video stream data of zones of different parallel.
Different from conventional video coding compression algorithm, the method more pays attention to the particularity demand of monitoring device, thus
Dynamic during video recording can adjust coding region, video pictures are divided into two kinds of static background and dynamic content not belong to together
The data flow of property, then carry out hybrid coding/broadcasting, is taken into account with the perfection that this to reach volume and effect.Therefore, this method is extensive
Video recording be applied to field of video monitoring preserves function, particularly in the case that the conversion of some scene content is less, permissible
Accomplish, on the premise of video quality is constant, the volume of storage file to be reduced to 1/10th of script.
Brief description
Fig. 1 is the operation monitored picture schematic diagram of the present invention.
Specific embodiment
Below present disclosure is carried out with more detailed elaboration:
The present invention will record a video region division be background area, secondary coding region and three, main code region rank, then pass through
The size to control the mode of corresponding coding quality to reduce output file for the different coding parameter of these regions setting.
As shown in the figure it is assumed that a monitored picture can be divided into background frame and two isolated areas, then pass through this method
Can set up three independent Video coding regions:
Region 1: static background area
, this region is generally fixed background taking banking terminal video capture device as a example, the region not having or seldom changing,
Therefore can targetedly be adjusted during coding, or even only be retained static images.
Region 2: main code region
It is same that this region is generally the main region of photographic head recognition of face taking banking terminal video capture device as a example, but
Effective time is typically shorter, during the monitoring video of a day 24 hours, the valid data time typically not greater than 1/3rd.
Region 3: secondary coding region
Although such region also seizure content can often, these data are often and to be not belonging to user of concern interior
Hold, we are by referred to as: miscellaneous letter data.For these data it is common practice to be encoded with relatively low quality standard.
Claims (3)
1. a kind of the method for video file volume is effectively reduced by dynamic area capturing technology it is characterised in that by video counts
According to collection, coding work, the mode according to dynamic data and static data to make a distinction, and for two kinds of different pieces of informations
Respective attributes set separate coding parameter, operate respectively.
2. method according to claim 1 is it is characterised in that comprise the steps:
Step 1: monitoring video flow is automatically divided into by more than one according to user's setting or dynamic area technology of identification different

Step 2: setting background area scope, set according to user and select minimum code level, or simply with background picture
Mode is substituted；
Step 3: the secondary coding region of setting, corresponding coding parameter is set for this region, by reducing crucial number of frames, reduction
The modes such as frame rate are weakening the bandwagon effect in this region；
Step 4: setting main code region, the coding parameter of different time sections is set for this region；
Step 5: arrive the related setting of step 4 according to step 2, start independent video coding process, then by data according to form
Require to be saved among unified file；
Step 6: identify fileinfo using corresponding player decoding plug-in, according to partition information in broadcast interface
Corresponding position fills the video stream data of zones of different parallel.
3. method according to claim 2 it is characterised in that
In step 4, higher coding quality is set within the busier time period, and dynamic image is less or blank phase
Interior reduction coding quality, to grasp the output of Video coding by way of dynamic conciliation.
