Description

TECHNICAL FIELD The present invention relates to the field of augmented reality, and in particular to a method for acquiring augmented reality content and a mobile augmented reality server and a client. BACKGROUND OF THE INVENTION With the improvement of the capabilities of mobile intelligent terminals and the maturity and development of mobile Internet technologies, Augmented Reality (AR) technology, which was once limited to the laboratory, has begun to enter the public field, and a large number of mobile terminal positioning and state perception Augmented reality applications based on multimedia information processing and presentation technology are beginning to emerge, and take advantage of the advantages of mobile Internet resources to expand information and enhance the experience of the physical world that users observe. This is called Mobile Augmented Reality (Mobile Augmented Reality, referred to as MobAR). This has caused great concern to all parties in the industry and has become a hot spot in current technology research and standardization. The research and application of mobile augmented reality technology, applying virtual augmented reality information to the real world, changing the way users observe the surrounding world. The traditional text-based input WEB page browsing query mode is transformed into camera-based shooting, capturing hotspots. A new mode of enhanced information in real time. MobAR users can use mobile smart terminals (such as mobile phones) to capture the real-life business experience while capturing the real world. The augmented reality application running on the terminal is based on the user's current context: terminal geographic fingerprint information (latitude and longitude, orientation, etc.), or the current camera's current real-life scene, capturing the AR target deployed by the AR service provider, such as the physical world. Entity associated point of interest (POI), and according to the user's choice to obtain augmented reality content (AR Content), including: text, picture, voice, video, and finally the acquired augmented reality content and the terminal camera shooting real scene on the screen fusion display, Get an unusual augmented reality business experience. In the existing augmented reality technology solution, the augmented reality target search and the augmented reality content acquisition process are generally initiated by the system according to the request of the augmented reality user terminal, which may be referred to as a PULL mode or a single request-response mode. The trigger mode realizes a single, instant association between real physical world information (user location, shooting real scene, etc.) and virtual augmented reality content (text, audio and video), which can meet the needs of most application scenarios. However, in the actual use of augmented reality services, some users tend to continue to pay attention to the augmented reality targets deployed nearby, and obtain corresponding enhanced content in time. In the traditional PULL mode, the user must repeat the transmission multiple times. Seeking, such an operation not only wastes air interface resources but also easily causes repeated downloads of the same information. On the other hand, if the corresponding enhanced content changes, or the user context is in a specific state, for example, the user enters an augmented reality target dense area, or the user opens the augmented reality terminal camera to capture the surrounding real scene, in the prior art solution, the system does not Any hints will be provided, and if the user does not initiate the request, the relevant augmented reality information may be missed. "Subscription-notification" is a common information exchange mechanism in the communication system. The requester can subscribe to the status of the information source and receive the corresponding change notification according to the rules. Related to this, the following problems exist in existing augmented reality business systems:

1) Searching for augmented reality target/content based on the request-response mode, there is a problem that the request must be repeated multiple times, resulting in cumbersome user operations, low execution efficiency, and repeated download of augmented reality information. 2) Searching for augmented reality targets/contents based on the request-response mode, there is a lack of active request to send prompts, resulting in the inability to timely acquire the augmented reality information of the user's attention.
