古建筑测绘方法适用性对比分析——以故宫钟粹宫为例

Comparison on the Applicability of Surveying and Mapping Methods for Ancient Buildings——Taking the Palace of Accumulated Purity (Zhongcui gong) in the Forbidden City as an example

摘要:

钟粹宫综合测绘项目探索了三维激光扫描、数字近景摄影测量、手工测量这三种技术在古建筑全要素信息采集过程中的应用方法；通过比对进行了数据的精度校验，并绘制了钟粹宫院落内各单体建筑的典型测绘图纸；在分析三种技术多方面特性的优缺点后，提出了根据实际需求选择适当技术的测绘模式。

Abstract:

The comprehensive surveying and mapping project of the Palace of Accumulated Purity (Zhongcui gong) explored the applications of three different technologies, namely 3D laser scanning, digital close-range photogrammetry and manual surveying, in the process of information collection of ancient architecture. Through comparison, the accuracy of the data is verified, and the typical drawings of individual buildings in the Palace of Accumulated Purity courtyard are drawn. After analyzing the advantages and disadvantages of the three technologies in many aspects, the appropriate technology for surveying and mapping are put forwards according to the actual needs.
