Research on Digital Media Tourism Publicity System under Computer Big Data Technology

This paper analyzes the current situation of the development of virtual tourism on the Internet and puts forward the function and technical requirements of virtual tourism system. At the same time, this paper designs a set of JSP mode architecture of virtual tourism system. In this paper, ArcGIS and 3DSMax are used to establish virtual ground model and virtual ground object model with different morphological characteristics, and all models are converted into VRML file format and optimized, which not only effectively integrates virtual ground model and virtual ground object model, but also takes into account the fidelity and display speed of the model. The system is divided into four functional modules: virtual scene roaming, exchange discussion area, online shopping area, system management and maintenance. The feasibility of this method is verified by the realization of virtual tourist landscape in the park.
