摘要
历史建筑数字化复原有助于建筑历史和文脉的研究,为建筑保护和修缮提供重要参考依据。本文以上海徐汇区的1座历史保护建筑为对象,研究点云逆向建模技术在历史建筑保护中的应用。使用Leica RTC 360三维激光扫描仪和高清数码相机获取建筑高精度的点云数据和纹理数据,经过数据预处理、部件化建模,构建精细的现状三维数字模型,并结合有关资料,对模型进行修改,复原80年前建筑的原始风貌。
The digital restoration of historical buildings is helpful to the study of architectural history and context,and provides an important reference for the protection and repair of the buildings.Taking a historical building in Xuhui district of Shanghai as an object,the application of point cloud reverse modeling technology in historical building protection is studied.Use Lecia RTC 360 3D laser scanner and HD digital camera to obtain high-precision point cloud data and texture data of the building.After data preprocessing and component modeling,a detailed current 3D digital model is constructed.Combined with the relevant information,the model is revised to restore the original appearance of the building 80 years ago.
