Illustrative methods
Fig. 2 illustrates the flow chart of the video data handling procedure according to the embodiment of the present application.
As shown in Fig. 2, the video data handling procedure according to the embodiment of the present application includes：S210 is adopted by the first image
Collection equipment acquisition includes the first video of object, and described first image collecting device has first resolution；S220, from described
The initial video frame of one video detects the initial attitude of the object；S230, determines whether the initial attitude of the object meets
First preassigned；And S240, meet first preassigned in response to the initial attitude of the object, triggering passes through the
The acquisition of two image capture devices includes the second video of object, and second image capture device has second resolution, and institute
It states second resolution and is higher than the first resolution.
In the following, will be described in detail each step.
In step S210, by the first image capture device 110, for example, first camera acquisition includes the first of object regarding
Frequently.Here, in order to reduce the operand and memory space of gesture recognition, described first image collecting device can have lower
First resolution.
In step S220, the initial attitude of the object is detected from the initial video frame of first video.
Fig. 3 illustrates the schematic diagram of the single frames estimation technique according to the human body attitude of the embodiment of the present application.
As shown in figure 3, the posture of human body can be detected from the single video frame in video.Specifically, can pass through
Emerging computer vision technique carries out the Attitude estimation of human body, face etc..For example, can be obtained from monocular or binocular camera
Image to the skeleton (head, shoulder, elbow, wrist, hip, knee, ankle etc.) and head pose (pitching or so and respective corners of human body
Degree) high-precision identification is carried out, and then estimate limbs correlation and fat or thin height.
In step S230, determine whether the initial attitude of the object meets the first preassigned.That is, by described in determination
Whether the initial attitude of object meets the first preassigned, it may be determined that whether the initial attitude of the object, which needs, is paid close attention to
Particular pose, for example, in the case where household guards scene, the lean forward posture or the posture that lies low etc. of human body.
Then, in step S240, in the case where the initial attitude of the object is the particular pose for needing to pay close attention to, triggering
Include the second video of object by the acquisition of the second image capture device 120.Here, in order to more obtain the concern figure being more clear
Picture, second image capture device can have higher resolution ratio.
Therefore, in the video data handling procedure according to the embodiment of the present application, the spy for detecting object is depended on whether
Determine posture, object is obtained by the first image capture device with different resolution and the second image capture device respectively
First video and the second video.In this way, can carry out including object by the second video with higher second resolution
The processing of the key frame of key poses, to improve the treatment effeciency of video data.
But in the case where the posture only for object is identified, it is understood that there may be can not clearly determine object
The case where behavior.For example, detect human body lean forward posture in the case of, can not accurately judge the follow-up behavior of human body, example
Such as, the follow-up behavior of human body can be the behavior of running of active, can also be passive to fall down behavior.
Therefore, in the video data handling procedure according to the embodiment of the present application, further according to the sequence of video frame, lead to
The gesture recognition of consecutive frame is crossed as a result, carrying out effectively identification (for example, the climbing of human body, sitting down, falling down) to behavior.
Fig. 4 illustrates the schematic diagram of the Activity recognition technology based on human body attitude according to the embodiment of the present application.Such as Fig. 4 institutes
Show, based on the human body attitude identified in continuous several frames, the behavior of human body can be gone out by posture recognition sequence.
For the identification of the behavior of object, the video data handling procedure according to the embodiment of the present application may include two and show
Example.
First, in the first example, can be in the case where confirmly detecting the specific behavior of object, just triggering passes through institute
It includes second video to state the acquisition of the second image capture device.In this way, can reduce with high-resolution second figure
As the probability of the error starting of collecting device.For example, first can be met determining the initial attitude detected from initial video frame
In the case of preassigned, after further determining that first detected in the first subsequent video frame after the initial video frame
Whether continuous posture also complies with first preassigned.Also, the specific appearance of user is detected in continuous multiple video frame
In the case of state, the behavior based on object described in posture recognition sequence.That is, in the video counts according to the embodiment of the present application
According in processing method, the first follow-up posture of initial attitude and first subsequent video frame based on the initial video frame is known
The behavior of the not described object.
Pass through the Activity recognition result of the object, it may be determined that the priority of the behavior of the object.That is, according to this
In the video data handling procedure for applying for embodiment, the object is determined according to the behavior classification information of the behavior of the object
Whether behavior is high priority behavior.Here, the high priority behavior refers to the behavior for the object for needing to pay close attention to, example
Such as, in the case where household guards scene, human body falls down behavior.Correspondingly, low priority behavior is the common behavior of the object, example
Such as, the behavior of walking about etc. of human body.
In this way, in the case where confirmly detecting the high priority behavior of the object, triggering passes through second image
Collecting device obtains second video, to ensure second image capture device not because unessential object behavior and
Error starting.
Therefore, in the video data handling procedure according to the embodiment of the present application, in response to the initial attitude of the object
Meet first preassigned, triggering can be wrapped by the second video S240 that the acquisition of the second image capture device includes object
It includes：Meet first preassigned in response to the initial attitude of the object, after first after the initial video frame
Continuous video frame detects the first follow-up posture of the object；Determine whether the first follow-up posture of the object meets described first
Preassigned；Meet first preassigned in response to the first follow-up posture of the object, determines the behavior of the object
It is the high priority behavior that priority is more than predetermined threshold；And in response to determining that the behavior of the object is the Gao You
First grade behavior, triggering pass through the second video that second image capture device acquisition includes object.
But in these cases, if the time span of the behavior of the object is longer, there are second images
The startup time of collecting device too late, to miss the possibility of key message.
Therefore, alternatively, in the second example, in the particular pose for detecting object, for example, the posture that leans forward of human body
In the case of, just triggering has the second video that high-resolution second image capture device obtains object.And subsequently, based on institute
The subsequent video frame for stating the first video determines whether to detect the high priority behavior of the object.It is described right confirmly detecting
In the case of the high priority behavior of elephant, keep obtaining second video by second image capture device.Also,
In the case of determining the high priority behavior that the object is not detected, that is, the initial attitude generation based on the object is accidentally opened
In the case of dynamic, stop obtaining second video by second image capture device.
Here, it will be understood by those skilled in the art that in the second example, based on the posture recognition sequence institute in video frame
The process for stating the high priority behavior of object is identical with the first example, here in order to avoid redundancy just repeats no more.
Therefore, it in the video data handling procedure according to the embodiment of the present application, may further include：From described initial
The first subsequent video frame after video frame detects the first follow-up posture of the object；Determine the first follow-up appearance of the object
Whether state meets first preassigned；Meet first preassigned in response to the first follow-up posture of the object,
Determine that the behavior of the object is the high priority behavior that priority is more than predetermined threshold；And it is described right in response to determining
The behavior of elephant is the high priority behavior, keeps through second image capture device acquisition including the second of object regarding
Frequently.
Also, it in above-mentioned video data handling procedure, can further include：After the first of the object
Continuous posture does not meet first preassigned, determines that the behavior of the object is not the high priority behavior；And response
It is not the high priority behavior in the behavior of the object, stops through second image capture device acquisition including object
The second video.
In the video data handling procedure according to the embodiment of the present application, pass through second image capture device in triggering
After obtaining second video, it can still maintain and first video is obtained by described first image collecting device.This
Sample can detect the posture of the object, so that it is determined that the behavior of the object from the video frame of first video.By institute
Stating the first video has low resolution, this can reduce time and resource consumption needed for gesture recognition.
While second image capture device obtains second video, after first subsequent video frame
The second subsequent video frame continue to detect the second follow-up posture of the object, and determine whether the second follow-up posture meets
Second preassigned.Here, the first above-mentioned preassigned is for judging whether the posture of the object needs to pay close attention to
The standard of particular pose, and the second preassigned here is for judging whether the posture of the object reflects the needs of object
The end of the high priority behavior of concern.Come for example, people regains one's feet after falling down, human body attitude experienced from the posture that leans forward
Revert to the process of midstance.Alternatively, people has stopped getting off after running, human body attitude also experienced from pose recovery of running
For the process of walk about posture or midstance.Therefore, whether meet second by the second follow-up posture of the determination object
Preassigned, it may be determined that whether the high priority behavior that the needs of the object are paid close attention to terminates.Also, in the height of the object
In the case that priority behavior terminates, stop passing through the second video that second image capture device acquisition includes object.
That is, in the video data handling procedure according to the embodiment of the present application, may further include：After described first
The second subsequent video frame after continuous video frame detects the second follow-up posture of the object；Determine the second follow-up of the object
Whether posture meets the second preassigned；Meet second preassigned in response to the second follow-up posture of the object, really
The high priority behavior of the fixed object terminates；And terminate in response to the high priority behavior of the object, stopping passes through institute
State the second video that the acquisition of the second image capture device includes object.
Here, it will be understood by those skilled in the art that it is described above based on being obtained with described first image collecting device
First video detects the beginning and end of the specific behavior of the object.But it is set triggering second Image Acquisition
It is standby obtain second video in the case of, the specific behavior of the object can be equally determined based on second video
Beginning and end.
First video is being obtained by described first image collecting device and passes through second image capture device
After obtaining second video, first video and second video can be further stored, is regarded for subsequent
Frequency handles and the operations such as inquiry.
In addition, as described above, if the first follow-up appearance detected in the first subsequent video frame of first video
State does not meet first preassigned, then illustrates that the behavior of the object is not the high priority behavior.In this way, due to not
The behavior for needing to pay special attention to the object stored in second video, can delete second video, be deposited with reducing
Store up the occupancy in space.
That is, in above-mentioned video data handling procedure, may further include：In response to the first follow-up appearance of the object
State does not meet first preassigned, determines that the behavior of the object is not the high priority behavior；And in response to institute
The behavior for stating object is not the high priority behavior, deletes second video.
Fig. 5 illustrates the flow chart of the video data acquiring process according to the embodiment of the present application.As shown in figure 5, in step
S310 starts low resolution camera.In step S320, low-resolution image is acquired with low resolution camera.In step
S330 obtains the posture information of object from the low-resolution image.In step S340, classified based on preset posture, behavior
Standard and the definition of the priority of behavior, by pattern-recognition and behavior grade separation, obtain the behavior class of the behavior of the object
Other information and precedence information.Next, in step S350, judge whether the behavior of the object is high priority behavior.
Step S360, the behavior in response to the object are high priority behaviors, start high-resolution camera.In step S370, with
High-resolution camera acquires high-definition picture.Finally, in step S380, high-definition picture is stored.In addition, equally in step
Rapid S280, the behavior in response to the object are not high priority behaviors, store low-resolution image.Also, in step S380
The behavior classification information and precedence information of the behavior for the object that step S340 before can also being stored in is obtained, this will
It is further illustrated below.
That is, during above-mentioned video data acquiring, using high-resolution and low resolution camera while work
Make, obtains image information.Wherein, low resolution camera is acquired and is stored image information in real time, is carried out at the same time object
The Activity recognition of gesture recognition and segment, and based on the given expression video frame of preset Anomaly standard (as lain down, falling down)
Critical precedence information, posture result, behavior label (that is, behavior classification information and/or precedence information) and described
The associated video segment information of behavior simultaneously stores.In addition, if it is high exception level, then high-resolution camera acquisition image is triggered
And store the label information of the behavior.
In addition, in the storing process of first video and second video, since second video includes closing
In the key message for the object behavior for needing to pay close attention to, and first video includes more general object behavior, therefore, with
Little compressible stores second video, while storing first video with high compression rate, to obtain better memory space
Utilization ratio.
It, can be according to the key of the video of acquisition when the capacity of storage device is by limited time that is, when video stores
Property distinguishing property of information compression.The video frame of low exception level is stored using high compression rate, and the video frame of high exception level is adopted
It is stored with little compressible.In this way, by storing compressed video, the capacity of storage device can be discharged.
Also, if the memory capacity of the storage device is less than predetermined threshold, it can preferentially retain second video,
And delete at least part of first video.
As described above, during storing first video and second video, in addition to storage described first regards
Other than the behavior classification information and precedence information of the object behavior of frequency and second video, described first can also be stored and regarded
The temporal information of frequency and second video.In this way, when deleting at least part of first video, can be based on described
The temporal information of first video deletes in first video time one or more video frame earlier, that is, have indicate compared with
One or more video frame of the temporal information of early time.
That is, when the memory capacity of storage device with high compression rate coding by that still cannot meet lasting recording
When demand, the deletion for carrying out storage content is needed to carry out Free up Memory.It is sorted according to the time order and function of video record, while to figure
As the priority of frame and video-frequency band is ranked up, retain the high video frame information of priority, at the same delete priority it is low and when
Between early video frame information, thus the memory capacity of storage device is discharged.
Fig. 6 illustrates the flow chart of the video data storing process according to the embodiment of the present application.As shown in fig. 6, first,
Step S410 obtains the precedence information of video and behavior.Then, in step S420, determine whether the behavior of object is Gao You
First grade behavior.If it is high priority behavior, then lossless or little compressible coding is carried out, and if not high priority row
For, then it is damaged or high compression rate encodes, and in step S430, the information after being encoded.Next, in step
S440 obtains the currently active memory space of storage device.Also, in step S450, whether judgement memory capacity is insufficient.In step
Rapid S460, if it is decided that lack of memory capacity then carries out time-sequencing according to the temporal information of video to video frame.Finally, exist
Step S470 deletes current earliest low priority video frame, while retaining high priority video frame, and return to step S440,
Obtain the currently active memory space of storage device.
Here, it will be understood by those skilled in the art that in the video data handling procedure according to the embodiment of the present application, and
It is not required the temporal information of storage first video and second video, or first video and institute must be stored
State the behavior classification information and precedence information of the behavior of the object in the second video.If at subsequent video data
Above- mentioned information need not be applied in reason, then need not store information above.For example, if the memory capacity of storage device is very big,
Erasing time video frame earlier is not needed, then need not then store the temporal information of video.
In addition, in the behavior classification information and precedence information of the behavior for storing first video and second video
In the case of, the behavior label of the behavior of the object can be generated based on described information, to which identification record has the object
Specific behavior second video.Also, the behavior label of the behavior based on the object can be generated further described
The breviary information of second video, for example, the thumbnail of second video.
Specifically, the behavior classification information of the behavior based on the object and the precedence information can select to remember
Record has in initial video frame or the first subsequent video frame in first video of the particular pose of the object at least
One, it is used as the breviary information of second video.
Therefore, in the video data handling procedure according to the embodiment of the present application, during checking video, Ke Yigen
The key label and posture, behavioural information stored while according to storage video, generates representative frame or representative segment, with
Convenient for fast browsing.
Also, when storing video, temporal information, behavior classification information and precedence information that can be based on the video
At least one of video is segmented.For example, video is divided into multiple video-frequency bands according to time order and function, wherein individually
Video-frequency band indicates the behavior of some classification, or the behavior with different priorities.For example, in people during falling down, according to
Temporal information, behavior classification information and precedence information, respectively storage table let others have a look at the regarding of the normal walking behavior before falling down
Frequently, the video (including people from the process got up on the ground) for falling down process of people and people continue normal walking after standing up
Video.
In this way, in subsequent video frequency searching, key label when being stored according to video and posture, behavioural information,
It can also object-based posture and behavior progress quick-searching.It specifically, can be based on the row of the behavior of the object
For classification information, retrieval indicates the specific behavior of object, for example, the video of people fallen down.Further, it is also possible to be based on the object
Behavior high priority message, retrieval includes the video of object behavior that needs are paid special attention to.Therefore, it is possible to reduce video is examined
The hand labor expended when rope.
That is, in the video data handling procedure according to the embodiment of the present application, may further include：Based on institute
State first video of at least one of temporal information, the behavior classification information and described precedence information retrieval storage
With second video.
For example, the video content to be retrieved or thumbnail image or video skimming can be checked according to time or period.
The video content to be retrieved or thumbnail image or video skimming can be checked according to the type of posture.It can also be according to behavior
Priority level comes the video content to be retrieved or thumbnail image or video skimming.
Therefore, according to the video data handling procedure of the embodiment of the present application, it can be based on object, such as the posture of human body is known
Not, Activity recognition detects crucial video frame either video clip also, key based on video frame or video clip,
Distinction acquisition, compression, storage, the capacity release of video are carried out, and quickly checks and retrieves.It is set in this way, improving storage
Standby effective storage capacity reduces the storage burden of storage device.Also, since the video clip of storage is convenient for inquiry and inspection
Rope, the user experience is improved.
