AR labeling method and system based on display content

The invention discloses an AR labeling method and system based on display content, and belongs to the technical field of intelligent wearable equipment. The method comprises the following steps: S1, analyzing display contents to be labeled, extracting contents capable of being labeled in the display contents for AI arrangement, automatically dividing the contents into a plurality of trigger sets according to the integrity of the contents capable of being labeled, and networking to carry out background preloading labeling on the content of the sets; according to the scheme, the watching focus of the user is combined with the active virtual cursor, the watching focus firstly ensures that unwanted annotations cannot be triggered at will in a slow triggering mode, and then the selected display content can be rapidly and accurately annotated in combination with secondary determination of the virtual cursor, so that the accuracy is ensured, and meanwhile, the user experience is improved. And labeling is carried out
