摘要: 国立西南联合大学遗址正遭受着一定程度的风化、腐蚀、损坏,遗址具有不可再生的唯一特征,一旦破坏则不可还原.笔者采用测绘地理信息技术,采集国立西南联合大学遗址的三维点云数据,在此基础上构建了较为典型的遗址三维模型,为国立西南联合大学遗址的数字化存档提供了宝贵的测绘地理信息数字资料,同时为弘扬国立西南联合大学提供一种新的三维数字模型.Abstract: The site of National Southwestern Associated University is being subjected to a certain degree of weathering,corrosion and damage.The site has the unique characteristics of non-renewable.So,once the site is destroyed,it cannot be restored.In this paper,geographic information mapping technology is used to collect 3D point cloud data of the National Southwestern Associated University.A typical site model of the National Southwestern Associated University is built based on these surveying and mapping data.This method provides valuable data for the digitalized archives of the National Southwestern Associated University monument and provides a new 3D digital model for publicity National Southwestern Associated University.
