Description

System and method for realizing mobile augmented reality service, terminal and server

technical field

The present invention relates to technologies for realizing mobile augmented reality services, and in particular to a system and method for realizing mobile augmented reality services, a mobile augmented reality terminal, and a mobile augmented reality server.

Background technique

With the maturity and development of smart terminals and mobile Internet technologies, augmented reality (AR, Augmented Reality) technology, which was once confined to laboratories, has begun to enter the public's field of vision. A large number of Internet/mobile Internet based on image recognition and terminal positioning technologies AR applications began to emerge, called mobile augmented reality (Mobile AR) applications, which has attracted great attention from the industry and has gradually become a hotspot in technology research.

The research and application of mobile augmented reality technology, applying virtual augmented reality information to the real world, has changed the way users observe the surrounding world—from the traditional WEB page browsing query mode based on text input to camera-based shooting, capturing Hotspot and view a new mode of enhanced information in real time.

Mobile AR users can use mobile terminals such as smart phones to obtain augmented reality service experience while shooting surrounding scenes. The main business scenarios include the following: the augmented reality application (ARApplication) running on the mobile terminal captures the deployment of AR service providers based on the user's current location. The augmented reality target (AR Target), such as the point of interest (POI, Point of Interest) related to the geographical location, and obtain the augmented reality content (ARContent) according to the user's choice, including text, picture, voice, video, and finally combined with the geographical location of the user terminal Fingerprint information, such as latitude and longitude, orientation, etc., is displayed on the screen by combining the obtained augmented reality content with the surrounding real scene captured by the terminal camera in real time, so as to obtain an unusual augmented reality business experience.

In the current market augmented reality solutions, different augmented reality service providers independently develop AR applications, and different AR applications are implemented based on different augmented reality technologies. The current augmented reality technologies mainly include the following: AR target recognition technology, AR content acquisition technology, AR content display technology, etc. As a result, AR applications developed by AR application developers for different AR service providers must be implemented using different technologies, which undoubtedly increases the difficulty of AR application development. AR users must choose to install different AR application operating environments according to the different AR service providers they subscribe to, which is very unfavorable for users to replace terminals. To replace the terminal, it is necessary to reinstall the operating environment of all AR applications, which undoubtedly greatly hinders the market popularization of AR applications.

In existing augmented reality solutions, since the AR applications released by AR service providers are incompatible with each other, AR applications cannot be sold online in a centralized manner, which will greatly reduce the number of subscribers of AR service providers. In addition, the AR service provider not only needs to deploy the AR service server, but also needs to independently undertake the design work of the AR content, which also increases the service operation cost of the AR service provider.

To sum up, traditional AR service providers carry out their own AR services based on their respective implementation technologies. As a result, the AR application market has not only been split, but also caused great inconvenience to the majority of AR users. At present, this has become a hindrance to the development of the AR service market. an important factor.
