圆明园西洋楼海晏堂基础信息采集与虚拟拼接研究

Information Collection and Sitching of Haiyantang Site,Western Building Region,Yuanmingyuan

位于北京圆明园长春园北端的西洋楼景区,曾由西方传教士与中国匠师合作建造,整个景区建筑与园林风格仿以巴洛克风格,并糅合了中国传统建筑工艺,是中西文化交流的灿烂史证,但历遭战争劫掠,如今的西洋楼遗址只见碎石土山。本文以西洋楼中海晏堂为案例,结合历史文献考证,利用传统测绘手段及三维激光扫描技术采集记录遗址构件信息数据,研究分析虚拟拼接技术在建筑类遗址中应用的技术实操性,并研究开发可对遗址构件信息进行管理、数据分析及展示的构件信息库体系。

Xiyanglou(Western Buildings)is located in the north of Yuanmingyuan’s(The Old Summer Palace)Changchunyuan in Beijing.It was designed and constructed collaboratively by Jesuit missionaries and the Chinese craftsmen.The entire scenic region,including buildings,fountains,sculptures,and gardens,were built in Baroque and Rococo style using traditional Chinese construction techniques.The significance of its restoration has drawn much attention from home and aboard in the field of cultural heritage conservation.But after a few more disasters over the course of history,the site had been severely damaged and was reduced to the ruin today.Taking Haiyantang as a case,this paper introduces the restoration research project which is based on the current-day survey of the ruins in combination with the historic archival research.Combining traditional means of surveying and three-dimensional laser scanning technology for acquiring and recording information of components on site to analyze the practical application of the virtual assembly technology on building sites,and exploit the Component database system which not only could be used to manage and analyze data,but also display the information.
