The invention discloses a multimedia implementation method and device based on AR and a two-dimensional code, and a storage medium, and belongs to the technical field of multimedia, and the technicalscheme comprises the steps: obtaining a first picture which is an initial picture collected by image collection equipment, constructing a three-dimensional model adaptive to the first picture, fusingthe first picture and the three-dimensional model to generate a second picture, acquiring audio information, encoding the second picture and the audio information through a two-dimensional code generation rule to generate a two-dimensional code, and generating a presentation identifier, wherein the presentation identifier comprises the two-dimensional code and the second picture. Compared with theprior art, the method at least has the following beneficial effects that the multimedia content can be displayed in multiple ways by comprehensively applying the AR technology and the two-dimensionalcode technology, the requirement of AR display on the terminal is reduced, and meanwhile, the display content is richer.
