Digital museum is an important trend in the development of museums in recent years, and virtual reality technology in the digital museum is one of the most important issues in museum construction and it has broad development prospects. This paper aims to research into two kinds of key virtual reality technologies: image-based 360 degree panoramic display and 3D modeling technology, exploring various kinds of virtual museums based on these two technologies. It discusses the advantages and limitations of the various kinds of VDMs and proposes the design of the Virtual Museum based on 360 - degree panorama, web 3D technology and 3D modeling technology. And its application in the design of Xiamen Overseas Chinese Museum has obtained good results.
Traditional data mining often focuses on the research of models and methods without considering of specific requirements in the field. This paper proposes a data mining framework in traffic field—Traffic Domain Data-Mining Framework (TDDMF) which is a domain-driven data mining framework based on ontology. The ontology model for traffic domain data based on TDDMF is also built in the paper. A prototype system is developed to prove the availability and effectiveness of TDDMF.
