Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in figure 1, a kind of storage method of monitor video, comprises the following steps：
Step 1：Monitor video is detected, to determine the effective video section and invalid video section in monitor video, wherein, effective video
Moving object be present in section, moving object is not present in invalid video section；
Step 2：Effective video section is stored, and invalid video section is deleted.
The storage method of the monitor video is by detecting the content in monitor video, to distinguish effectively regarding in monitor video
Frequency range and invalid video section, a large amount of static invalid images are deleted, only there will be the effective video section of moving object to store
Come, reduce the duration of monitor video, reduce the storage area that monitor video takes.
Wherein, as shown in Fig. 2 the method that monitor video is detected in step 1 comprises the following steps：
Step 1.1：Countershaft intercepts to the picture in monitor video successively on time；
Step 1.2：A later frame capturing picture and former frame capturing picture are contrasted；
Step 1.3：If a later frame capturing picture is different with former frame capturing picture, judge between this two frames capturing picture
Moving object in video-frequency band be present, be effective video section；If a later frame capturing picture is identical with former frame capturing picture, judge
Moving object is not present in video-frequency band between this two frames capturing picture, is invalid video section.
When front and rear frame capturing picture difference, representing in the video-frequency band must be there occurs the movement of object, then the video-frequency band
Maximum probability is valuable, should be stored；When front and rear frame capturing picture is identical, representing may be without generation thing in the video-frequency band
The movement of body, then the video-frequency band maximum probability is unworthy to delete.
In step 1.1, the picture in monitor video is intercepted successively by default time interval or frame number interval,
In order to improve the accuracy to effective video section and the judgement of invalid video section, the interval time of capturing picture should be short as much as possible,
It is preferably but not limited between 0.05 ~ 1s, or, the interval frame number of capturing picture should lack as much as possible, be preferably but not limited to
Between 10 ~ 100 frames.
The monitor video is that shooting that captured in real-time obtains or prior obtains.
The storage method of the monitor video is mainly used in two kinds of scenes：
First, applying in the course of work of monitoring system, monitoring system one side captured in real-time obtains monitor video, while to prison
Control video is detected, and effective video section is stored in the RAM card of itself or is stored in long-range control by data cable
In terminal processed or by the way that in network storage beyond the clouds server, invalid video section is deleted；
Second, applying in the later stage backup of monitor video, the monitor video that operating personnel shoot monitoring system acquisition in advance is led
Enter into processing software, processing software is detected to monitor video, and effective video section is carried out to be extracted for storage backup, will
Invalid video section is deleted.
Embodiment two
As shown in figure 3, a kind of monitoring system, including micro control module and the photographing module of the difference micro control module electrical connection, with
And with the micro control module by circuit or data cable or the storage module of network connection, wherein：The micro control module is used for
The monitor video that the photographing module captured in real-time obtains is detected, to determine effective video section and the invalid video in monitor video
There is moving object in section, effective video section, moving object is not present in invalid video section；And effective video section is stored in institute
State in storage module, and invalid video section is deleted.
Monitoring system one side captured in real-time obtains monitor video, while being detected to monitor video, to distinguish monitoring
Effective video section and invalid video section in video, the effective video section in monitor video is stored in the storage module,
Invalid video section is deleted, a large amount of static invalid images can be removed, only retain the effective image that moving object be present, reduce
The duration of monitor video, reduce the storage area that monitor video takes.
The storage module can be the RAM card being connected with the micro control module by circuit, or with the micro-control
The remote control terminal that module is connected by data cable, or the cloud service for passing through network connection with the micro control module
Device.
The micro control module includes interception unit, comparison unit and the execution unit being sequentially connected, wherein：
The interception unit is used for countershaft on time and the picture in monitor video is intercepted successively, and capturing picture is sent to
The comparison unit；
The comparison unit is used to be contrasted a later frame capturing picture and former frame capturing picture, and comparing result is sent
To the execution unit, wherein：If a later frame capturing picture is different with former frame capturing picture, judge to intercept picture in this two frame
Moving object be present in video-frequency band between face, be effective video section；If a later frame capturing picture and former frame capturing picture phase
Together, then judge moving object is not present in the video-frequency band between this two frames capturing picture；
The execution unit is used for the comparison structure according to the comparison unit, and effective video section is sent to the storage module
Inside stored, invalid video section is deleted.
When front and rear frame capturing picture difference, representing in the video-frequency band must be there occurs the movement of object, then the video-frequency band
Maximum probability is valuable, should be stored；When front and rear frame capturing picture is identical, representing may be without generation thing in the video-frequency band
The movement of body, then the video-frequency band maximum probability is unworthy to delete.
The interception unit is intercepted to the picture in monitor video successively by default time interval or frame number interval,
In order to improve the accuracy to effective video section and the judgement of invalid video section, the interval time of capturing picture should be short as much as possible,
It is preferably but not limited between 0.05 ~ 1s, or, the interval frame number of capturing picture should lack as much as possible, be preferably but not limited to
Between 10 ~ 100 frames.
The photographing module includes colored camera module and infrared photography module, in feelings such as brightness relatively low night, cloudy days
Under condition, still the second best in quality monitor video can be obtained by starting the infrared photography module.
Embodiment described above only expresses embodiments of the present invention, and its description is more specific and detailed, but can not
Therefore the limitation to the scope of the claims of the present invention is interpreted as, as long as the skill obtained using the form of equivalent substitution or equivalent transformation
