AR live-action map dynamic label superposition method, system, device and medium

The invention provides a method, a system, equipment and a medium for dynamically superposing labels on an AR live-action map, which are applied to a webpage client and comprise the following steps of: acquiring video decoding information; analyzing SEI frame information in the video decoding information to obtain AR label information; generating and rendering an operable label layer according to the AR label information; in response to a user operation, changing the operable label layer; obtaining new AR label information according to the changed operable label layer; outputting the new AR label information to a back-end server, so that the back-end server updates the SEI frame information according to the new AR label information; and in response to update information sent after the client monitors and updates the SEI frame information, re-rendering the operable label layer. Through webpage program development, the method for dynamically superposing the labels on the AR live-action map has cross-platform pe
