Behavior synchronization is the key link in VR social intercourse systems.Virtual image and the behavior synchronization of user refer to：When a use
After a concrete behavior is made at family, also made in the virtual scene that the corresponding virtual image of the user is safeguarded in VR servers identical
Or corresponding behavior, and the behavior that the virtual image is made can be by other under the user oneself and the virtual scene
Observed by user.For example, user blinks, which also blinks, and here it is identical behaviors；User is by pressing control
The directionkeys of handle, the virtual image is just towards the corresponding direction walking of direction key, and here it is corresponding behaviors.In data Layer
Face, user behavior is corresponding with behavioral data, makes the behavioral data that the client of the user of behavior is obtained according to it, it will be able to
In the synchronization for locally realizing user behavior, i.e. user oneself can see oneself virtual shape by the VR display devices of client
The behavior of elephant.Meanwhile the client for making the user of behavior needs behavior data being uploaded to VR servers, then serviced by VR
By behavior data distributing to the client of the other users under same virtual scene, the user of these clients can lead to device
The VR display devices for crossing respective client see the behavior for making the corresponding virtual image of the user of behavior.
In the prior art, behavioral data is handed down to the client of the other users under same virtual scene, using
Simple broadcast mode sends each client same data, therefore its data volume being related to is very big, gives VR servers
Bring greatly operation burden.To mitigate VR server stress, have to take two kinds of measures in the prior art, first is limitation
The number of participating user under same virtual scene, second is the content of simplified behavioral data, such as is only wrapped in behavioral data
Location information containing user.For the first measure, the participation number of VR social activities is limited, necessarily leads to the application scenarios of VR social activities
Limitation is received, it is made to may be only available for the Social behaviors in microcommunity.For second of measure, simplify behavioral data content, it must
So cause the behavior of virtual image cannot be consistent or corresponding with the real behavior of the user corresponding to the virtual image, significantly
Weaken the Core Superiority of VR social activities relative to traditional internet social activity in terms of authenticity.In short, the prior art is in VR societies
The user behavior synchronization aspects of friendship lack effective solution, cause user experience poor.
Inventor proposes that a kind of data of VR servers for being applied to communicate to connect with multiple client are same through studying for a long period of time
One step process and device to solve the above problems, improve the user experience during VR social activities.Obviously, the method for data synchronization and
Device can be also used for in other VR systems other than VR social activities, such as VR game, VR education, VR cooperation training, VR it is long-range
In the products such as cooperation, MR cooperations.
First embodiment
VR servers and multiple client communication connection.In the VR social intercourse system beginningizations that VR servers provide, can create
Virtual scene, including contents such as landform, object, the personages in scene.The user of each client is entering VR social intercourse systems
Afterwards, which can all carry out time synchronization with VR servers, really each between guarantor's client and VR servers and with other
Time consistency between a client, this time consistency are also the follow-up basis for carrying out user behavior synchronization.In user
After logging on to VR social intercourse systems, system can create corresponding virtual image, and meeting according to the specific requirements of each user for it
A socket channel for being used for data transmission, in subsequent step, client are created between VR servers and each client
The synchronization of the socket channel consummatory behavior data is utilized between end and VR servers.
Fig. 3 shows the flow chart of method of data synchronization provided in an embodiment of the present invention.With reference to Fig. 3, this method includes：
Step S10：When first user of the first client in the multiple client makes a behavior, from described
One client obtains behavioral data corresponding with the behavior.
First client can be any one client in multiple client, and the first user refers to that the client corresponds to
User.The behavior that first user makes can be the arbitrary act including expression, action etc., and behavioral data refers to
One client by behavior harvester it is collected, for characterize the first user behavior total data, including first
User performs the various kinematic parameters of corporal parts involved during the behavior, such as the head of the first user, hand, body
The data such as dry operating position, speed, the posture waited.In short, the first user can be made right in virtual scene by behavioral data
The virtual image answered reproduce the first user make behavior or realization is corresponding with the behavior made of the first user
Behavior.
As a kind of embodiment of step S10, the first client presses the behavioral data that subordinate act harvester obtains
Prefixed time interval (such as 30 frame per second) is sent to VR servers, so that VR servers can obtain the behavior number of the first user
According to.As the another embodiment of step S10, the behavioral data that the first client obtains subordinate act harvester is sentenced
It is disconnected, determine whether behavior data correspond to significant behavior, in result for when being, behavior data just are sent to VR services
Device, so that VR servers can obtain the behavioral data of the first user, for example, the first user body in its natural state is slight
Mobile may be considered does not have influential behavior to VR social activity results, without sending it to VR servers.
Step S11：In the behavioral data category will be sent to the matched first part's behavioral data of the first class of subscriber
In the second client of first class of subscriber, so that the second user of second client is able to observe that the VR clothes
At least frame first for first user corresponding with first part's behavioral data being engaged in the virtual scene that device is safeguarded
Image.
Step S12：By in the behavioral data with second user categorical match with first part's behavioral data not
Same second part behavioral data is sent to the third client for belonging to the second user classification, so that the third client
Third user be able to observe that first user corresponding with the second part behavioral data in the virtual scene
At least second image of frame.
Method is identical used by step S11 and step S12, and only corresponding main body is different, and step S11 is directed to
It is the second client, step S12 is directed to third client.Be illustrated below mainly for step S11, step S12 with
Its is similar.
Second client is any one client different from the first client, and second user refers to that the client corresponds to
User, the first user and second user must be the users under same virtual scene, otherwise in the first client and the second visitor
Progress behavioral data synchronizes nonsensical between the end of family, and in elaboration below, for convenience of description, the user being previously mentioned each means
User under same virtual scene.
VR servers can pre-set multiple class of subscribers and corresponding classifying rules, by its in addition to the first user
His user classifies, and it is same that the corresponding client of the user to belonging to different user classification sends different data progress behaviors
Step.The first class of subscriber in step S11 is one in above-mentioned multiple class of subscribers, can also be had including in step S12
Other users classification including second user classification.Second user is the use for belong to after above-mentioned classification the first class of subscriber
Family, since second user and the second client are corresponding, so alternatively the second client belongs to the first class of subscriber.For
The corresponding client of each user in each class of subscriber, the synchronizing process of behavioral data can be with reference in step S11
The second client behavioral data synchronizing process carry out, will not enumerate.
Fig. 4 shows the flow chart of the step S11 of method of data synchronization provided in an embodiment of the present invention.With reference to Fig. 4, step
S11 can include：
Step S110：Obtain user's weight of the second user.
Step S111：The second user is divided to by first class of subscriber based on user's weight.
Class of subscriber can be divided for characterizing the size of the weighted value of user personality based on one, which is claimed
For user's weight.First class of subscriber has preset weighted value range, when user's weight of the second user of acquisition is in the
When in the range of the preset weighted value of one class of subscriber, second user is divided to the first class of subscriber.Wherein, the first class of subscriber
A specific class of subscriber is not represented, the first class of subscriber refers to the class of subscriber where second user, i.e. second user
Which class of subscriber is divided into, which is thus referred to as the first class of subscriber, what step S110 and step S111 were illustrated
It is the process that second user is divided to the first class of subscriber.
Fig. 5 shows the flow chart of the step S110 of method of data synchronization provided in an embodiment of the present invention.With reference to Fig. 5, step
Rapid S110 can include：
Step S110a：Obtain the second user for characterize user's importance priority weighting and/or, be based on
The position relationship of second user described in the virtual scene and first user obtain the position weight of the second user.
Step S110b：User's weight is obtained based on the priority weighting and/or the position weight.
The acquisition of user's weight of second user can be there are many mode：
The first embodiment, will be for characterizing the priority weighting of user's importance as user's weight.For example, judge
Whether second user is VIP user, if result is yes, priority weighting is larger, if the result is negative, priority weighting compared with
It is small.In step S111, second user can be divided to VIP class of subscribers or ordinary user's classification.In another example judge second
Whether user is scene management person, if result is yes, priority weighting is larger, and if the result is negative, priority weighting is smaller.
In step S111, second user can be divided to administrator's classification or ordinary user's classification.In another example judge second user
Whether be broadcasting user, i.e., whether the user has important messages to be broadcasted to other users, if result is yes, priority power
Weight is larger, and if the result is negative, priority weighting is smaller.In step S111, second user can be divided to broadcasting user
Classification or ordinary user's classification.Example is above are only, any restrictions are not formed to protection scope of the present invention.
Second of embodiment, will be for characterizing the position relationship of second user and the first user in the virtual scene
Position weight is as user's weight.Position weight can be based on virtual scene in the distance between second user and the first user with
And visible level obtains.Wherein, the distance between second user and the first user just refer to that second user is corresponding in virtual scene
Virtual image and the corresponding virtual image of the first user it is separated by a distance in virtual scene.It for example, can be on VR servers
Default following rule, using the position where the virtual image of the first user as the center of circle, its position of user power within its 2m
Weight is 100, is more than 2m apart from it but its position weight is 50 no more than the user of 5m, is more than 5m but no more than 10m's apart from it
Its position weight of user is 10, and it is 0 to be more than its position weight of the user of 10m apart from it.Assuming that the second user in virtual scene
With the first user interval 3m, then the position weight of second user is 50.Obviously, above-mentioned rule is merely illustrative, not to the present invention's
Protection domain forms any restrictions.It is generally also contemplated that when determining position weight visible between second user and the first user
Property, it is seen that property refers to whether the two can mutually be observed and more in virtual scene by the visual angle of respective virtual role
It can mutually be observed in big degree.Visibility can pass through, but be not limited by a visible property coefficient to characterize, for example, the
There is no any object between two users and the first user, then, it is seen that property coefficient 1；Across one between second user and the first user
Stifled stone walling, then, it is seen that property coefficient 0；Across a stifled glass wall between second user and the first user, then, it is seen that property coefficient is
0.8；Second user is under street lamp light, and the first user is in street lamp shade, then, it is seen that property coefficient 0.5.Obviously, it above are only
Example does not form any restrictions to protection scope of the present invention.When considering visibility, the position that can will be obtained based on distance
Weight is multiplied by visible property coefficient and obtains final position weight, for example, second user and the first user interval 3m in virtual scene,
The position weight of second user is 50, but does not see other side across a stifled stone walling, the two between second user and the first user, the
The final position weight of two users should be 0.
It is convenient to illustrate, it is assumed that it is fully visible between all users under virtual scene, i.e., temporarily ignore visibility problem,
The position weight that is obtained at this time by distance i.e. final user's weight is preset with following class of subscriber, position power on VR servers
It is neighboring user classification that weight, which is 100, and it is close to class of subscriber that position weight, which is 50, and it is ordinary user that position weight, which is 10,
Classification, it is far from class of subscriber that user's weight, which is 0,.Second user and the first user interval 3m, second user in virtual scene
Position weight for 50, in step S111, second user can be divided to close to class of subscriber.
The third embodiment, while consider in priority weighting and second of embodiment in the first embodiment
Position weight, obtain user's weight.For example, simplest situation, the two is added as user's weight, it certainly can be with base
User's weight is obtained in other preset formulas or algorithm.In step S111, user's weight based on second user is according to pre-
If user classification rule be divided to the first class of subscriber.
Step S112：First part's behavioral data is sent to second client.
First part's behavioral data is the subset with the behavioral data of matched first user of the first class of subscriber, first
Divide behavioral data that can show the first level of detail of the behavior.For example, behavioral data includes head, hand, trunk etc.
Whole action datas.First part's behavioral data can only include header data, and at this moment the virtual image of the first user uses the
A part of behavioral data is only possible to produce headwork, i.e., roughly reproduces the behavior of the first user, and behavior details is seldom.First
Divide behavioral data that can also only include the data on hand and head, at this moment the virtual image of the first user uses first part's behavior
Data can generate headwork and hand motion, i.e., reproduce the behavior of the first user substantially, there is certain behavior details.Certain
A part of behavioral data can also include whole behavioral datas, and at this moment the virtual image of the first user uses first part's behavior
Data can generate headwork, hand motion, body work, i.e., accurately reproduce the behavior of the first user, and behavior details is enriched.
In step S110 and step S111, user is divided to different class of subscribers, it can be to different user classification
User send different data and carry out behavior synchronization, so as to meet the diversified demand of the user of different user classification.
For example, class of subscriber includes VIP class of subscribers and ordinary user's classification in previous example, in the number that VR servers can be handled
According to measure it is limited in the case of, it should preferentially meet the needs of VIP user.If the first class of subscriber is VIP class of subscribers, send out
Whole behavioral datas can be included by giving first part's behavioral data of the second client, so that the second of the second client uses
Family (VIP user) can observe that corresponding with first part behavioral data first in virtual scene uses by VR display devices
The virtual image at family, i.e., at least first image of frame generated in the second client based on first part's behavioral data, first
The virtual image of user is made that the part behavior corresponding to first part's behavioral data.If the first class of subscriber is commonly to use
Family classification, then header data can only be included by being sent to first part's behavioral data of the second client.
In addition, synchronizing process of the user to behavioral data of different user classification can be directed on the basis of user classifies
It optimizes.For example, class of subscriber includes neighboring user classification in previous example, close to class of subscriber, ordinary user's classification
And far from class of subscriber.For the user in neighboring user classification, the virtual shape of the first user of distance in virtual scene
As closest, the full details of the behavior of the first user ought to be seen, if the first class of subscriber is neighboring user classification, the
A part of behavioral data can be including whole behavioral datas including head, hand, trunk；For close to the use in class of subscriber
Family, the virtual image of the first user of distance is relatively in virtual scene, it can be seen that the behavior of the first user it is main
Details, if the first class of subscriber is close to class of subscriber, first part's behavioral data can include header data and hand number
According to；For the user in ordinary user's classification, the virtual image with the first user in virtual scene has certain distance, can be with
See a small amount of details of the behavior of the first user, if the first class of subscriber is ordinary user's classification, first part's behavioral data
It can include header data；For the user in separate class of subscriber, the virtual shape of the first user of distance in virtual scene
Behavior details as farther out, being substantially not visible the first user, in other words the behavior of the first user have little significance to it, such as existing
Two people hardly pay close attention to people except 10m in chat in What in reality, if the first class of subscriber is far from user
Classification, first part's behavioral data can not include any data, need not carry out behavior synchronization at this time in other words, second use at this time
The virtual image of the first user observed by family or its make appearance before behavior.
In the above example, behavior synchronization process is optimized according to mutual distance of the user in virtual scene,
Only need to see that the user VR servers of whole behavior details are just sent to the behavior number with whole behavior details really
According to other users only need the part behavioral data for being sent to have less behavior details, do not send any data even.It is this
Optimisation strategy significantly reduces the data volume during behavior synchronization, significantly reduces the operating pressure of VR servers so that same
It is social that one virtual scene can support more users to participate in, and the participating user of each social activity can obtain and oneself wish to see
The behavior details arrived, user experience are good.It is appreciated that according to the difference of class of subscriber division result, it can also be formulated
His optimisation strategy optimizes the synchronizing process of behavioral data.
For step S12, it is similar with step S11, is no longer specifically described.As an alternative embodiment,
Before step S11 is performed, VR servers can first obtain user's weight of the every other user in addition to the first user, right
User's weight is ranked up, and takes the top n user (N is a preset constant, such as takes N=20) of ranking results, and it is N number of to exclude this
The virtual image of the first user of distance is more than the user of pre-determined distance (such as 100m) in user, and step S11 is performed to remaining users,
The synchronizing process of behavioral data can be advanced optimized.
In conclusion method of data synchronization provided by the invention, it, can be to different user class for same user behavior
Other user sends different data and carries out behavior synchronization, disclosure satisfy that the demand of different classes of user, and basic herein
On the synchronizing process of behavioral data can also be optimized, such as the embodiment of the present invention further directed to different classes of user
Proposed in the optimization method based on distance, using after these optimal ways, the data volume during behavior synchronization is notable
Decline, VR server stress is substantially reduced, and user experience is improved.
