The Digital Reconstruction And Digital Display Of Tibetan Temple Architecture

Taking the Tibetan Buddhist temple building in Yongbrakang as an example,this study realized the 3D reconstruction of Tibetan temple building through 3D laser scanning technology,tilt photography technology and close-range photogrammetry technology,providing a feasible digital scheme for the data retention,protection,restoration and display of the ancient architectural heritage of the people and ethnic groups.In addition,this study applies 3D digital technology and network information technology to the protection,display and dissemination of Tibetan traditional architectural culture,which realizes the innovation of Tibetan traditional architectural form and the transmission mode of architectural culture,and contributes to the better dissemination of Tibetan traditional architectural culture.In conclusion,the main contents of this paper mainly include the following points:1.Realized the collection of three-dimensional data of Lama Bakang building.Through 3D reconstruction of traditional Tibetan temple building and demonstration research,yungbulakang palace architecture for the data collection,including three-dimensional point cloud data,oblique photographic image data,unmanned aerial vehicle(uav)local photo shoot panoramic video,digital camera,and data that is collected by processing get floor plan,3D model building,etc.2.Study and summarize the 3D reconstruction methods of Tibetan temple architecture.Experiments using a variety of ancient building surveying and mapping methods,yungbulakang palace,for example,according to the 3D reconstruction object is different,with buildings,structures,mountain ring scene classification,respectively,using 3 d laser scanning technology,tilted aerial photography,close shot photogrammetry technology gets yungbulakang palace architecture of data from a variety of sources,implements the Tibetan temple architecture and environment of each part digitization reconstruction,Tibetan temple architecture are summarized through the experiment of 3 d reconstruction scheme.In addition,problems such as format conversion and data registration of multi-source data fusion have been explored and solved,which provides a method for the fusion of aerial photography data and three-dimensional scanning data,and helps to better play the digital value of ancient architectural surveying and mapping data..3.Study and summarize the digital display scheme of 3D objects.Experiments to deal with multiple source data processing,multiple formats of 3 d object is obtained by different techniques,such as 3 d point cloud,the three-dimensional model,pictures of the panoramic video,in order to cooperate with different format data show browsing,choose a variety of exhibition projects,such as Wish3 D,Trimble refused Real Works,Potree,Mars and Venus,and according to different web side,move the applicable issued digital display solutions are summarized.4.Summarized the scheme for the acquisition and processing of surveying and mapping data of multi-source ancient buildings.A variety of 3D data were obtained by using 3D laser scanning and UAV tilt photography.In this process,the detailed processing process of point cloud in the later stage of 3D laser scanning is summarized in detail,including five basic processes of point cloud data acquisition,point cloud data registration,point cloud sampling and dilution,point cloud denoising and classification,point cloud output and format conversion,which provides reference and reference for the point cloud processing of other ancient buildings.In the process of aerial photography field,the operation scheme of UAV in the process of data acquisition is summarized,including UAV ground operating system,flight path and parameter setting,etc.,and the advantages and disadvantages and application fields of constructing 3D real scene model based on UAV tilt photography technology are expounded.
