摘　　要：在遗产保护中,文物的数字化是一项基础性工作,高精度的文物遗产数字模型能够记录文物的三维空间信息以及纹理信息,为文物的保护、展示、修缮等工作提供重要的数据支撑。本文针对南京城墙铭文砖的数字化采集需求,结合城墙本身的特点,研究了一种采用带状倾斜摄影+贴近摄影的技术方法,获取不同尺度的城墙影像数据,建立高精度的城墙三维模型,同时,借鉴测绘地理信息行业遥感解译的技术方法,构建砖文“属性”知识库,搭建城墙铭文砖“空间+属性”的地理信息管理系统,阐述了南京城墙铭文砖数字化采集的工艺流程,探索了一种针对城墙铭文砖数字化采集和保护的方法。In the protection of cultural heritage,the digitization of cultural relics is a basic work.The high-precision digital model of cultural heritage can record the three-dimensional spatial information and texture information,which provides important data support for the protection,display and repair of cultural heritage.Combining with the characteristics of Nanjing City Wall and aiming at the digital collection requirements of its inscription bricks,this paper researched a technical method of using strip oblique photography+proximity photography to obtain image data of different scales of the city wall and built a high-precision three-dimensional(3D)model of the city wall.At the same time,this paper built a brick inscription database and a city wall inscription brick geographic information management system by drawing on the technical methods of remote sensing interpretation in the surveying and mapping geographic information industry,which expounded the technological process of digital collection of Nanjing city wall inscription bricks and explored a method for digital collection and protection of city wall inscription bricks.
