Or it is identical, this can be configured with demand according to the actual situation.
In some preferred embodiments, the type for the current kinetic event that the basis is determined, carries out shape of leaving home of being in
The step for judgement of state S104 comprising:
S1041, when the type for determining current kinetic event is to enter event type, then by the record number for the event of entering
IN1 adds 1, and determines that current state is state of being in；And/or
S1042, when the type for determining current kinetic event is to go out event type, then by the record number for the event of going out
After OUT1 adds 1, according to the note of current resident population N, the record number IN1 of current event of entering and current event of going out
Record number OUT1 calculates the number M that is currently in, and according to the calculated number M that is currently in, carries out the state of leaving home of being in
Judgement.Due in embodiments of the present invention, the state of being in refers to the state of at least 1 people of family, and it is described from
Family's state is then the state that there is no one at home, thus using current resident population N, currently enter event record number with
And the record number for event of currently going out calculates number of being currently in (i.e. somebody's number inside current family), it can be accurately
Number of being currently in is calculated, to further improve accuracy in detection.
In some embodiments, the basis currently reside population, currently enter event record number and work as
Before go out event record number calculate currently be in number the step for comprising:
Calculate the difference between the record number IN1 for event of currently entering and the record number OUT1 for event of currently going out
Value, i.e. IN1-OUT1；
The number of being currently in is obtained after the calculated difference is added with the currently resident population.
In some preferred embodiments, described according to the calculated number of being currently in, carry out the state of leaving home of being in
Judgement the step for comprising:
When it is described it is calculated be currently in number M greater than 0, then determine that current state is state of being in；
When it is described it is calculated be currently in number M equal to 0, then determine that current state is state of leaving home；
When it is described it is calculated be currently in number M less than 0, then the calculated current number of being in is set to 0, and
Determine that current state is state of leaving home.As it can be seen that current determining current state is to leave home when as long as calculated M is less than or equal to 0
State.Wherein, the case where M is less than 0, it may be possible to have thief or other people not from doorway enter, at this time should also further by
The state of leaving home is pushed to except client, it is also necessary to be issued prompting message to client, be used the user of client can to enable
It is checked and is confirmed, can also achieve the effect that security protection in this way.
In some preferred embodiments, the currently resident population N is determined by following steps:
The record number IN1 and the record for event of currently going out of event of once currently entering are calculated every prefixed time interval
Absolute difference I between number OUT1, i.e. I=ABS (OUT1-IN1)；For example, being opened from 5 points of every morning (i.e. 5:00a.m)
Begin, was calculated every 30 minutes between the record number IN1 for event of once currently entering and the record number OUT1 for event of currently going out
Absolute difference, then experience 24 as a child, i.e., 1 day, then obtained 48 absolute differences, I at this time1、I2、I3、……、
I48, wherein I1It is expressed as the 1st calculated absolute difference.As it can be seen that if prefixed time interval is different, and start to calculate
Time point and end calculate time point setting difference, then the number for then obtaining absolute difference then can be different, i.e. IkIt indicates
For kth time calculated absolute difference, then k=1,2,3 ..., K, the value of K can be according to different the case where actual set
And it is different；
When reaching preset time point, then numerical value is that maximum difference is exhausted from choosing in several obtained absolute differences
To value；For example, from I1、I2、I3、……、I48In, select the maximum absolute difference of numerical value, such as I35；In addition it is also possible to first
X period is preset, maximum absolute difference in each period is then first found out, then again from the absolute difference acquired
In select the maximum absolute difference of numerical value；
As absolute difference (such as I selected35) identical as preceding primary calculated resident population, it is determined that
The absolute difference selected is currently to reside population；
When the absolute difference selected and preceding primary calculated resident population be not identical, then confirmation is sent
It requests to client, and determines currently to reside population according to the confirmation message returned by client is received.
Specifically, it since the resident size of population of one family may generate variation because of various factors, then needs
Population is resided to family to confirm, and each finally confirms that obtained resident population can be stored in database
In, in this way as absolute difference (such as I selected35) and preceding primary calculated resident population Np-1It is identical, it is determined that institute
State absolute difference (such as I selected35) it is currently to reside population NpIf but I35With Np-1Not identical, then needing will be true
Recognize request and be sent to client, wherein the confirmation request contains I35With Np-1Not identical this case information, to enable client
The display of the confirmation request is carried out after receiving this confirmation request, and can further be issued prompt and (such as be enabled client
End vibration issues voice, prompt tone), remind user to check that after user checks and confirms situation, client can then be returned really
Then the information (the i.e. described confirmation message) recognized is determined current normal according to the confirmation message returned by client is received
In population.Wherein, the confirmation message that may include that there is something special in the confirmation message, at this point, then by I35As Np；Alternatively,
It is can wrap in the confirmation message containing the resident population confirmed, then will confirm that and reside population included in information
As Np；Finally, will confirm that good current resident population NpIt is stored in database profession.
The embodiment of the invention also provides a kind of detection method of state of leaving home of being in, the step of specifically including following institute
Show.
Step S201, the type of current kinetic event is determined.Wherein the step S201 includes following sub-step.
S2011, video capture is installed at home and carried out to camera, video figure is obtained from the video that shooting obtains
As sequence, that is, acquire several video images.
S2011, the motion profile of the moving target is obtained after carrying out motion target tracking to sequence of video images.
In the present embodiment, the specific embodiment of the motion target tracking is shown in steps are as follows.
1) mixture Gaussian background model, is established, then video image is carried out using the mixture Gaussian background model
Division between moving target and background.
It is close to one probability of the distribution maintaining of pixel point value each in scene for the mixed Gauss model algorithm
Function is spent, the value of specific pixel each in scene is gone to be fitted with several (generally taking 3~5) Gaussian Profiles, each
The case where Gaussian Profile has the weight of oneself, therefore it can handle multi-modal background distributions.On the other hand, mixed Gauss model
It is to parameterize, the parameter meeting adaptive updates of model, and do not have to cache past video frame, in this way in the mistake of algorithm process
Cheng Zhong can go the weight, mean value and variance that update each Gaussian Profile of each pixel with the arrival of new images.
Firstly, certain specific pixel point pixel value is X in moment ttProbability be:
Wherein, K illustrates the number of selected distribution, is mainly determined by hardware computing capability and available memory,
And in the present embodiment, K is preferably chosen for 3~5.ωn,tIt is the weight in n-th of Gauss model component of moment t, andIt is Gaussian probability-density function, specific as follows shown:
Wherein, μ heren,tWithThe respectively mean value and variance of n-th of Gauss model component of t moment.And it each newly arrives
The pixel value X cometK Gaussian Profile corresponding with it goes to match.If XtIn λ times of standard deviation of some distribution, it may be assumed that
|Xt-μn,t|<λσn,t
It is denoted herein as XtThe distribution is matched；λ is deviation factor.To the model component matched, its parameter can
It is updated by following equation:
ωn,t=(1- α) ωn,t-1+α
μt=(1- ρ) μt-1+ρXt
Herein, α and ρ is model component weight learning rate and model parameter learning rate respectively, and α can be defined by the user, i.e., certainly
Definition.It, can will be with if currently any one Gauss model component of the pixel value that newly arrives and the pixel does not all match
