Research On Reconstruction Of Interactive Ancient Virtual Sites On The Internet

"The First Warehouse in the World" Fengtu Yicang provides detailed historical data for studying ancient Chinese warehouse culture,granary architecture art and military offensive and defensive,so it has important practical significance for its protection.Traditional methods of protecting ancient sites are not only time-consuming and labor-intensive,but may also cause secondary damage to ancient sites.With the development of science and technology and computer technology,Internet and virtual reality technology has become a new technology for digital protection of ancient sites.It not only realizes the restoration and protection of ancient sites,but also can quickly spread the culture of ancient Chinese sites to all parts of the world.This topic takes the creation of the virtual scene of the ancient site Fengtu Yicang,the human-computer interaction roaming and the web page interactive roaming as the research object.The specific work is as follows:(1)Creation of the virtual scene of the ancient site Fengtu Yicang.Through the analysis of the ancient site of Fengtu Yicang,using geometric modeling and image modeling based on the combination of modeling techniques,3ds Max software combined with CAD drawings to create 3D models,and 3D model mapping and rendering,while using the modular modeling method improves the modeling efficiency.The Unity3 D engine refers to the built-in environmental resources to realize the rapid creation of natural environments such as flowers,trees and sky in the virtual scene,and optimizes the scene model by using Billboard technology.(2)The design and implementation of the somatosensory interaction of the virtual scene of the ancient site Fengtu Yicang.The improved joint filtering algorithm for simplifying the Gaussian kernel function by using the condition of increasing the position of the cavity and the fast Gaussian variation is used to realize the effective filtering of the depth image acquired by Kinect.The segmentation strategy is used to distinguish the human body from the background,and the machine learning is used to evaluate and determine the human body.At the same time,Kinect will track the precise posture of the human body to realize the natural interactive roaming with the virtual scene,realize the autonomous roaming of the virtual scene through the first person perspective,and realizethe fixed path roaming of the scene by using the three Hermite curve.(3)Implementation of interactive virtual platforms on the Internet.In the Unity3 D engine,the virtual scene of the ancient site Fengtu Yicang is published as Web GL format,the webpage layout is carried out by Web3 D technology,the data is transmitted by using the correlation function between the Unity3 D engine and the webpage,and the webpage virtualization is realized according to different roaming modes selected by the user.Roaming of the scene.Experiments show that the research results of this subject can not only effectively protect the site of Fengtu Yicang,but also allow more people to understand the Chinese warehousing culture,and propose a new idea for the future travel mode,so that make users enjoy the world beauty without leaving home.There are 57 pictures,5tables,and 64 references.
