AR knowledge service method and system based on high-precision spatial positioning

The invention discloses an AR knowledge service method and system based on high-precision spatial positioning. The method comprises the following steps of: identifying an object as a knowledge service object and calculating a high-precision spatial positioning coordinate of a selected position by utilizing a first carrier terminal through a graph acquisition device; media resources are aggregated through high-precision spatial positioning coordinates by using a graphic processing technology to form AR knowledge service data which can be used for AR knowledge service. According to the method provided by the invention, the media resources are associated with the spatial positions corresponding to the knowledge service objects in combination with a high-precision spatial positioning mode, and the associated media resources are correspondingly presented in combination with the spatial positions identified by the user terminal during presentation, so that a good application experience can be provided for a user, a
