Road and the detailed description of method, in case unnecessary details hinders description of the invention.
Before addressing detailed embodiments of the invention, first virtual reality interaction flow is briefly described, in order to
More fully understand the present invention.The interaction flow of virtual reality is usually：Obtain the dynamic of user and catch data (three-dimensional space position), root
Catch data according to dynamic and determine positional information of the user in virtual scene, then according to the heat transfer agent and use of the user received
Positional information of the family in virtual scene, corresponding interaction response is carried out, and by response results simultaneous display to user.Will response
As a result the mode of operation for being shown to user is usually：According to response results and the visual angle of user, the tune of progress respective virtual scene
It is whole, the helmet that the virtual scene after adjustment is worn by user is then shown to user.
It should be noted is that during virtual interacting, the dynamic acquisition mode for catching data of user can have it is a variety of,
Such as inertia it is dynamic catch, laser is dynamic catches or optics is dynamic catches, in the follow-up embodiment of the present invention, will by optics is dynamic catch exemplified by be said
It is bright.
The virtual reality interaction of the embodiment of the present invention is specifically based on the dynamic virtual reality interaction caught of optics.Based on optics
In the dynamic virtual reality interaction for catching technology, the observed object (1 of optical imaging system (multiple move catches camera) identification can be utilized
Or it is more personal) on the optical markings point that adheres to, the coordinate of mark point is calculated by the dynamic image capturing system processing for catching camera
Positional information, then it is transferred to the dynamic server (abbreviation camera server) for catching camera through network (wired, wirelessly, USB etc.).Phase
Machine server receives the next automatic co-ordinate position information for catching camera, and (co-ordinate position information is position of the user in physics scene
Information), observed object is identified according to the location coordinate information, the positional information of user is obtained, realizes and user is positioned.
It is understood that if camera server will position to user, then the image information of the same user received is necessary
Come from two and different dynamic catch camera.
Specifically, camera server determines three of a certain user in physics scene according to the location coordinate information received
After tieing up positional information, the three dimensional local information is also sent to the virtual scene client of corresponding user (when in virtual interacting
During an only user, virtual scene client is also virtual scene server simultaneously；When there is multiple users in virtual interacting,
Virtual scene client and virtual scene server separate, and virtual scene server is used to control each virtual scene client
Work-based logic).I other words the camera that is to catch that virtual scene client receives gathers, after camera server is handled
Three dimensional local information of the user in physics scene.The three dimensional local information can be mapped to virtual field by virtual scene client
A certain position in scape, it may thereby determine that positional information of the user in virtual scene.When there is multiple use in virtual interacting
During family, the positional information can be uploaded to by virtual scene client it is determined that after positional information of the user in virtual scene
Virtual scene server.
Illustrated below by specific embodiment.
Fig. 1 shows the schematic flow sheet of the first embodiment of virtual reality exchange method provided by the invention, in order to just
In explanation, the part related to the embodiment of the present invention is illustrate only, details are as follows：
Step 101, receive to catch the image information of camera and the heat transfer agent from collector, the image information automatically
Identify positional information of the user in virtual scene.
When there was only a user in virtual interacting, due to the mutual information transmission of user is now not present, therefore can
So that without the server for still further introducing virtual scene, (in other words, now server and client side's conjunction two of virtual scene is
One).When there is two or more users in virtual interacting, the information transmission mutual due to user now be present, therefore need
The server of virtual scene is introduced separately into, to realize the information transmission between each user.In embodiments of the present invention, with void
Intend illustrating exemplified by an only user in interaction.
The executive agent of the present embodiment can be the client of virtual scene.In virtual reality interaction, virtual scene visitor
The quantity at family end is identical with number of users.In existing virtual reality interaction, virtual scene is mainly based on game.It is appreciated that
Be that the virtual scene of the embodiment of the present invention is not limited to play, can also be the virtual scene in other application field, as studio,
Educational training, military exercises etc..
The image information received in this step is specifically three dimensional local information of the user in physics scene, according to physics
Corresponding relation between scene and virtual scene, you can some position for mapping to the three dimensional local information in virtual scene,
So as to obtain positional information of the user in virtual scene.
In addition, collector is specifically as follows inertial navigation unit such as gyroscope, it is attached to user, passes through gyroscope
, can be by wired or wireless such as bluetooth after the heat transfer agent (heat transfer agent includes speed and acceleration information) for obtaining user
Mode is sent to virtual scene client corresponding to the user, the client of the corresponding virtual scene of a user.Wherein, pass
Sense information can include the speed and acceleration information of all users, and acceleration information can be specially six-axle acceleration.
Step 102, user behavior of the user in virtual scene is determined according to heat transfer agent.
Client can determine user behavior of the user in virtual scene according to the heat transfer agent received.Wherein use
Family behavior is the various actions of user, such as：Stretching, flexure operation, click action or shaking motion of user etc..When
So, other action behaviors of user can also be included.It can be carried on the back and existed by user and client can be knapsack main frame, during use
Back, such user can break away from the constraint of traditional wire rod when carrying out virtual interacting, extend activity space.
Step 103, virtual scene is rendered according to the positional information, user behavior and the Viewing-angle information of the user and shown
Give the user.
It can be seen from description above, the corresponding client of a user (user carries on the back a knapsack main frame).Visitor
Family end is receiving the positional information and user behavior and then the Viewing-angle information for combining user in virtual scene of user,
The helmet that the game virtual scene of suitable user perspective can be rendered and worn by user is shown to user.
The virtual reality exchange method of the embodiment of the present invention, client determine that user exists by the dynamic image information for catching camera
Positional information in virtual scene, and the heat transfer agent gathered by collector determines user row of the user in virtual scene
For the virtual scene that suitable user perspective watches can be rendered with reference to user perspective information.Compared with prior art, client
When progress virtual scene renders, combine to move and catch data and sensing data, and especially highlight and user behavior is rendered, because
This virtual reality exchange method of the invention can strengthen virtual reality and hand over accurately by the operational feedback of user into virtual scene
Tractability, iconicity and the vividness of user behavior during mutually.
It should be noted that because user is persistent movement in interaction, therefore system also needs to gather next frame
The heat transfer agent of image information and subsequent time, and obtain the positional information and user behavior of user's subsequent time, and according to
The real-time motion state in family upgrades in time virtual scene,, can be with so after step 103 is performed to realize the feeling of immersion of interaction
Return continues executing with step 101.
In addition, it can be seen from description above, client needs to determine user in virtual scene according to heat transfer agent
User behavior.So it is specifically as follows in execution step 102：According to heat transfer agent, the attitude information of user is identified, then basis
Attitude information determines user behavior of the user in virtual scene.Below, will be described in detail by Fig. 2 embodiment.
Fig. 2 is the schematic flow sheet of the second embodiment of virtual reality exchange method provided by the invention, for the ease of saying
It is bright, the part related to the embodiment of the present invention is illustrate only, details are as follows：
Step 201, receive to catch the image information of camera and the heat transfer agent from collector, the image information automatically
Identify positional information of the user in virtual scene.
Step 202, according to heat transfer agent, the attitude information of user is identified.
Because heat transfer agent includes the speed and acceleration information of user, therefore according to the speed and acceleration information,
The attitude information of the user can be identified.
Step 203, whether the attitude information identified in judgment step 202 meets preparatory condition.
Step 204, if the determination result is YES, it is determined that user behavior of the user in virtual scene is corresponding for preparatory condition
User behavior；And enter step 205.
Step 205, virtual scene is rendered according to positional information, user behavior and the Viewing-angle information of user and is shown to use
Family.
Step 206, if judged result is no, virtual field is rendered according to the Viewing-angle information of the positional information and user
Scape is simultaneously shown to user.
In step 203, preparatory condition can be default various threshold conditions in virtual reality interaction, for sentencing
Whether the operation of disconnected user meets certain behavior act.Wherein, preparatory condition can be：Distance threshold condition, bone bending threshold
Value condition, bone stretching, extension one or more of threshold value and threshold speed condition.On judging whether attitude information meets
One or more of threshold condition is stated, the behavior act of user can be identified.
For example, if preparatory condition is：The distance between thumb and middle finger are less than predetermined threshold value and finger bone is bent
More than predetermined threshold value, then action of the user behavior corresponding to the preparatory condition for bending finger is defined.Now, if being believed according to posture
Breath determines the thumb of user and the distance between middle finger satisfaction meets to be more than less than predetermined threshold value and the flexibility of finger bone
During predetermined threshold value, it is determined that user behavior of the user in virtual scene is the action of bending finger, such as holds virtual field
The behavior of some object in scape.When so rendering virtual scene in step 205, then need according to positional information, user behavior
And the Viewing-angle information of user renders virtual scene (virtual scene includes user and holds the dynamic of some object in virtual scene
Make) and user is shown to, as shown in Figure 3.
It is understood that the example of above-mentioned identification user behavior is not exhaustive, in actual use, can be according to reality
The characteristics of demand analysis user behavior, and range information, bone bending information, bone are stretched corresponding to the preset in advance user behavior
The threshold condition of information and velocity information is opened up, to reach the purpose that user behavior is identified.

In the specific implementation, collector 602 for example can be：Inertial navigation unit such as gyroscope, it is attached to user,
After the heat transfer agent (heat transfer agent includes speed and acceleration information) that user is obtained by gyroscope, wired or nothing can be passed through
Line virtual scene client as corresponding to the mode of bluetooth is sent to the user, the client of the corresponding virtual scene of a user
End.Wherein, heat transfer agent can include the speed and acceleration information of all users, and acceleration information can be specially six axles
Acceleration.
It can be seen from description above, the corresponding client of a user (user carries on the back a knapsack main frame).Visitor
Family end is receiving the positional information and user behavior and then the Viewing-angle information for combining user in virtual scene of user,
The helmet that the game virtual scene of suitable user perspective can be rendered and worn by user is shown to user.
The virtual reality interactive system of the embodiment of the present invention, client determine that user exists by the dynamic image information for catching camera
Positional information in virtual scene, and the heat transfer agent gathered by collector determines user row of the user in virtual scene
For the virtual scene that suitable user perspective watches can be rendered with reference to user perspective information.Compared with prior art, client
When progress virtual scene renders, combine to move and catch data and sensing data, and especially highlight and user behavior is rendered, because
This virtual reality interactive system of the invention can strengthen virtual reality and hand over accurately by the operational feedback of user into virtual scene
Tractability, iconicity and the vividness of user behavior during mutually.
It is above-mentioned mainly describe one realize virtual interacting scene (i.e. in virtual interacting only have a user feelings
Condition), but in the virtual interacting application of reality, the often more than one people of progress virtual interacting in scene.Therefore, it is also desirable to
Consider the scene of more people's virtual interactings.
It should be noted that when there was only a user in virtual interacting, due to the mutual letter of user is now not present
Breath transmits, therefore can not have to server (in other words, the now server of virtual scene and the visitor for still further introducing virtual scene
Family end is combined into one).When there are two or more users in virtual interacting, passed due to the mutual information of user now be present
Pass, it is therefore desirable to the server of virtual scene is introduced separately into, to realize the information transmission between each user.Therefore, realizing
During more people's interactions, virtual reality interactive system 600 also includes：Virtual scene server 605.Also, because a user is corresponding
One client 603, a user use a Helmet Mounted Display 602, then when there is multiple users, the quantity of client and
The quantity of Helmet Mounted Display also can accordingly increase.
In more people's interaction scenarios, user behavior of the client except to identify itself corresponding user, it is also necessary to know field
The user behavior of other users in scape.Meanwhile client is except will position user corresponding to itself, while also need to obtain
Take the positional information of other users in scene.Client in scene is obtained the positional information of all users and user behavior it
Afterwards, virtual scene corresponding with reality can be rendered completely.For all clients in virtual scene, each client
The operation principle and flow at end are similar, are illustrated below with the workflow of a client.
On the basis of above-mentioned single interaction, client 603 also needs to the first heat transfer agent being uploaded to virtual scene clothes
Business device 605；And receive second user behavior and the second confidence of the second user that the virtual scene server 605 transmits
Breath；Second user behavior is determined according to the second heat transfer agent of the second user；And according to the first position information,
Second place information, first user behavior, second user behavior and the Viewing-angle information of first user render virtually
Scene, and first user is shown to by the Helmet Mounted Display 604.
When the virtual reality interactive system of the embodiment of the present invention, client render the scene of more people interaction, it is necessary to according to the
First position information of one user in virtual scene, second place information of the second user in virtual scene, the first user
The first user behavior, the second user behavior of second user, and combine the Viewing-angle information of the first user is corresponding to carry out
Virtual scene renders.Compared with prior art, client combines to move and catches data and sensing when progress virtual scene renders
Data, and especially highlight and each user behavior in scene is rendered, therefore the virtual reality interactive system of the present invention can
Accurately by the operational feedback of each user into virtual scene, strengthen virtual reality interaction in user behavior it is fine
Property, iconicity and vividness.
