Interactive sand table demonstration method based on 2D code and augmented reality technologies

Abstract

The invention provides an interactive sand table display method based on 2D code and augmented reality technologies, comprising the following steps: a physical plane map sand table includes multiple 2D physical models; a 2D code tag is fixed on the outer surface of each 2D physical model; and for each 2D physical model, a unique corresponding 3D physical model is built. A visitor holds a mobile terminal with a hand, starts an APP, and scans the 2D code tags pasted on the physical plane map sand table. At the moment, 3D building models corresponding to all the 2D code tags within the shooting field can be displayed at corresponding positions, and a display mode combining a real scene and a virtual scene is realized. In addition, each 2D code tag is bound with building explanation and introduction information. After a displayed 3D building model is clicked, the explanation and introduction of the building can be displayed in a web mode, and self-help tour guide is realized through explanation voice. Thus, the visiting experience of visitors is enhanced comprehensively.

Description

technical field [0001] The invention belongs to the technical field of interactive sand table display, in particular to an interactive sand table display method based on two-dimensional codes and augmented reality technology. Background technique [0002] A sand table is a model used to miniaturize topography or buildings for easy observation. At present, it has been widely used in military and commercial activities. [0003] However, the traditional sand table is mainly a solid flat sand table. Although it has the advantage of being easy to manufacture, it still has relatively large limitations in terms of display effect and audience experience, and can no longer meet people's needs. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides an interactive sand table display method based on two-dimensional code and augmented reality technology, which can effectively solve the above problems. [0005] The technical scheme tha...
