The No_Remaining Historic Park's Virtual And Visual Protection Technology Research In Luoyang City

The Landscape cultural heritage,so called historic park,is a importand part of cultural heritage.From the beginning of last centuary,the Research on the protection of historic garden heritage in China has basicly gone over The followingfour stages:Historical gardens are identified as "protected subjects",the interpretation of the "authenticity" of historical garden Heritage,the protection of the diversity of historical gardens and the study on the preservation of No_remaining historic garden Heritage.Among them,the No_remaining historic garden means the historic park which was built in early history and currently ruined because of Dynastic change and wars.They were recorded in historic literature,found by Archaeologists,Buried underground with no Ground remains.These gardends are mainly distributed in the historical region of Guanzhong and Central Plains,now called Shanxi and Henan district.The study on the preservation of No_remaining historic garden has fallen behind greatly Compared to which has Ground remains.However,some scholars have also carried out some valuable theoretical research and practical work.At the same time,the authenticity of the historical garden is mainly reflected in its cultural value and spiritual connotation,so the digital restoration is a better method of protection.In this paper,took Bai Juyi's private garden at lvdao lane for example,the author researched the application of Virtual reality and augmented reality technology in the field of preservation of no_remaining historical park in the Central Plains,attempted to explore the application of digital technology in the field of landscape heritage protection and used an example to solve the dilemma of digital technology in application.Firstly,this paper reviewed the present study mode of preservation of No_remaining historic garden Heritage at home andabroad,and the research course and present situation for digital technology such as virtual reality in the field of cultural heritage protection,then the research route of digital technology was put forward,which is to restore the historic garden that no longer exists with the Two kinds of virtual visualization technology of VR and AR.After that,the author analysed the representative historic gardens in the research area,attempted to build a comprehensive value evaluation index system for no_remaining historic garden heritage and carried out the actual investigation,scoring,analysis to six following Luoyang garden in Tang and Song Dynasties with the evaluation system,which are Bai Juyi Lvdao garden,Pei Du Lake garden,Niu Sengru Guiren garden,Shao Anle garden,Fu zheng garden and Li Renfeng garden.According to the score,the historic garden comprehensive value sorting is Bai Juyi Lvdao garden>Niu Sengru Guiren garden>Pei Du Lake garden>Fu zheng garden> Li Renfeng garden>Shao Anle garden.Finally,the author choosed the Bai Juyi Street Garden as the research object of digital reproduction.On the basis of the above scores and the results of the selection,the author carried out a detailed analysis of the construction of Bai Juyi Lvdao garden.According to Bai Juyi's poems and other related documents,the garden layout and the style and features of gardens and buildings were analyzed and reduced,and returned to the original condition and shape in concept.On the basis of the above,the author draw out the planar restoration and perspective restoration,Therefore,the theoretical foundation and basis for the digital reproduction research project were established.The last part of this paper introduced the practical operation of the digital technology reproduction research of Bai Juyi Lvdao garden,Systematically revealed some basic considerations,main steps and processes of digital reproduction of historical gardens including the selection of software and hardware platform,The overall framework of virtual reproduction system,Project file management,the Workflow of digital virtual garden scene modeling and The model construction of specific elements such as plants,rocks and buildings.Finally,this paper introduced the realization mechanism and principle of interactive function of digital virtual garden system.
