Technical Field
The invention relates to the field of communication, in particular to a transmission method of augmented reality information and a mobile augmented reality server.
Background
With the maturity and development of intelligent terminals and Mobile internet technologies, Augmented Reality (AR) technologies once limited to laboratories begin to advance to the public, and a large number of internet/Mobile internet AR applications based on image recognition and terminal positioning technologies begin to emerge, called Mobile AR applications, which attract great attention in the industry and become a technological research hotspot.
Research and application of a mobile augmented reality technology apply virtual augmented reality information to the real world, and a brand new mode that a user observes the surrounding world, namely a traditional WEB page browsing query mode based on text input, is changed into a mode based on camera shooting, hot spots are captured, and the augmented information is browsed in real time is changed.
The mobile terminal (such as a smart phone) is utilized by the mobile terminal (mobile ar user) to shoot surrounding scenes and obtain the augmented reality service experience at the same time: an augmented reality Application (AR Application) running on a terminal captures an augmented reality Target (AR Target) deployed by an AR service provider, such as a point of interest (POI) related to a geographical location, based on a current location of a user, and acquires augmented reality Content (AR Content) according to a user selection, comprising: characters, pictures, voice and videos are finally combined with geographic fingerprint information (such as longitude and latitude, orientation and the like) of the user terminal, the acquired augmented reality content and surrounding scenes shot by the terminal camera in real time are displayed on a screen in a fusion mode, and unusual augmented reality service experience is acquired.
The augmented reality target searching and augmented reality content acquiring process in the traditional augmented reality implementation scheme is usually executed by a system according to a received augmented reality user terminal related request, and can be called as a PULL mode or a single request-response mode, the service triggering mode realizes single and instant association between real physical world information (user position, real scene shooting and the like) and virtual augmented reality content (characters, audio and video), and can meet the requirements of most application scenes.
However, in the actual application process of the augmented reality service, some users tend to pay attention to the augmented reality target and its augmented content deployed nearby continuously (and the user location changes continuously), if such service is provided based on the traditional PULL mode, the user must repeatedly send the request for many times (search for the augmented reality target based on the latest location), and such operation is not only cumbersome, but also easily causes the same information to be repeatedly downloaded. On the other hand, if the augmented reality object of interest to the user is mobile (such as a person or a vehicle) or the corresponding augmented content changes, even if they are very close together in the conventional mode, the system will not provide any prompt if the user is not aware of it without actively initiating the request, and thus the relevant information may be missed.

Example 4
Based on the augmented reality implementation system shown in fig. 3, the invention also provides a transmission method of augmented reality information. As shown in fig. 5, the flowchart of the mobile augmented reality server 306 in the preferred embodiment receiving a subscription request of the mobile augmented reality client 304, and searching and acquiring nearby augmented reality content/target according to the location change of the user terminal specifically includes the following steps:
step 1-4(F1, P1, F2-F4), according to the user operation instruction or the logic of the augmented reality application service, the mobile augmented reality client sends an augmented reality content/target subscription request to the mobile augmented reality server, and requests that the augmented reality content/target can be acquired near the position of the receiving user terminal. Upon request, an augmented reality content/target subscription function in the mobile augmented reality server creates associated augmented reality content/target push settings, comprising: augmented reality content/target push filtering criteria, augmented reality content/target push triggering conditions, and the like. In this example, assume that the filtering criteria are augmented reality object types such as: "restaurant", the triggering condition is that the user terminal location enters a specific area, such as: "commercial pedestrian street".
The augmented reality content/target subscription function sends a subscription request for information related to the trigger condition in the subscription push setting, in this example, a change in the location of the subscriber terminal, to the augmented reality personalization and context function in the mobile augmented reality server.
Step 5-8(F5-F8), supporting the service server, such as: and the positioning server acquires the position information of the user terminal and sends the position change information of the user terminal to the mobile augmented reality server. The augmented reality personalization and context function sends a trigger condition (user terminal location) state change notification to the augmented reality content/target subscription function according to the subscription request.
Without loss of generality, the mobile augmented reality server can also receive the position change information of the user terminal through other means, including: the mobile augmented reality client sends the terminal position to a mobile augmented reality server;
and 9-12(P2, F9-F11, P3, F12), judging whether the augmented reality content/target push triggering condition is met or not by the augmented reality content/target subscription function according to the position information of the user terminal. In this example, assuming that the user has entered the preset push trigger area, the augmented reality content/target subscription function sends an augmented reality content/target acquisition request to the augmented reality content/target selection function in the mobile augmented reality server according to the filtering criteria in the push setting, and the latter requests the augmented reality content/target management function to search for an augmented reality target, select and acquire related augmented reality content according to the user terminal position and the filtering criteria.
In this step, the mobile augmented reality server may need to request the augmented reality content publisher, i.e., the augmented reality content server, to obtain the actual content of the augmented reality content.
Step 13-18(P4, F13-F18), the mobile augmented reality server pushes the acquired augmented reality content/target directly to the user terminal based on an underlying push mechanism (such as oma pause) via the augmented reality content/target delivery function, or first sends an augmented reality content/target push notification and then requests the acquisition of the augmented reality content/target actual content by the mobile augmented reality client.
And 19-22(P5, F19, P6, F20-F22), after a period of time, according to the user operation instruction or the logic of the augmented reality application service, the mobile augmented reality client sends an augmented reality content/target unsubscribe request to the mobile augmented reality server, and no longer subscribes the position near the user terminal to obtain the augmented reality content/target. According to the request, the augmented reality content/target subscription function in the mobile augmented reality server deletes the associated augmented reality content/target push setting, and simultaneously requests the augmented reality personalization and context function to cancel the trigger condition state subscription notification.
Example 5
Based on the augmented reality implementation system shown in fig. 3, the invention also provides a transmission method of augmented reality information. As shown in fig. 6, the mobile augmented reality server 306 receives a subscription request from the mobile augmented reality client 304, identifies an augmented reality target to be subscribed, and obtains a flowchart of corresponding augmented reality content according to a target position change, which specifically includes the following steps:
step 1-5(F1-F3, P1, F4-F5), according to the user operation instruction or the augmented reality application service logic, the mobile augmented reality client acquires an augmented reality target image or image feature description, sends an augmented reality content/target subscription request to the mobile augmented reality server, and requests to subscribe the augmented reality content/target corresponding to the image frame.
And the augmented reality content/target subscription function in the mobile augmented reality server sends an augmented reality target identification request to the augmented reality content/target selection function, and the request identifies the augmented reality target to be subscribed. The augmented reality content/target selection function requests the augmented reality content/target management function to perform augmented reality target matching based on the image frame or image feature description.
Step 6-8(P2, F6-F8), the augmented reality content/object subscription function creates relevant augmented reality content/object push settings according to the subscription request and the matching augmented reality object, including: augmented reality content/target push filtering criteria, augmented reality content/target push triggering conditions, and the like. In this example, assume that the filtering criteria are related augmented reality content media types, such as: "video", the trigger condition is that the augmented reality object enters a region close to the user, such as: "within 100 meters".
The augmented reality content/target subscription function sends a subscription request for information related to the trigger condition in the subscription push setting to the augmented reality personalization and context function in the mobile augmented reality server, in this case, to subscribe to the identified augmented reality target location change.
Step 9-12(F9-F12), supporting the service server, such as: and the positioning server acquires the position of the augmented reality target and sends the position information of the augmented reality target to the mobile augmented reality server. The augmented reality personalization and context function sends a notification of the change in trigger conditions (augmented reality target location) to the augmented reality content/target subscription function according to the subscription request.
And step 13-16(P3, F13-F15, P4, F16), the augmented reality content/target subscription function judges whether the augmented reality content/target push trigger condition is met according to the position of the user terminal and the position information of the augmented reality target. In this example, assuming that the augmented reality target has entered a region close to the user terminal, the augmented reality content/target subscription function sends an augmented reality content acquisition request to the augmented reality content/target selection function in the mobile augmented reality server according to the filtering criteria in the push setting, and the latter requests the augmented reality content/target management function to select and acquire the relevant augmented reality content according to the augmented reality target identification and the filtering criteria.
In this step, the mobile augmented reality server may need to request the augmented reality content publisher, i.e., the augmented reality content server, to obtain the actual content of the augmented reality content.
In steps 17-22(P5, F17-F22), the mobile augmented reality server pushes the acquired augmented reality content/target directly to the user terminal based on an underlying push mechanism (such as oma pause) via the augmented reality content/target delivery function, or first sends an augmented reality content/target push notification and then requests the acquisition of the augmented reality content/target actual content by the mobile augmented reality client.
And 23-26(P6, F23, P7, F24-F26), after a period of time, according to the user operation instruction or the augmented reality application service logic, the mobile augmented reality client sends an augmented reality content/target unsubscribe request to the mobile augmented reality server, and does not subscribe the augmented reality content corresponding to the augmented reality target any more. Deleting the associated augmented reality content/target push settings according to the request mobile augmented reality server augmented reality content/target subscription function, and simultaneously requesting augmented reality personalization and context function cancellation trigger condition state subscription notification.
