综合测绘技术在古建筑现状勘察中的应用研究——以养心殿东配殿综合测绘项目为例

Taking the Comprehensive Surveying and Mapping Project of the East Side of Yangxin Hall as An Example

养心殿东配殿综合测绘,是养心殿研究性保护工作基础测绘的专题研究内容,通过三维激光扫描、近景摄影测量、传统手工测量等技术方法,全面采集了东配殿的空间、纹理、现状形制特征、历史遗迹等文物本体信息。同时,研究了各类测绘技术的适用性、支撑性、效率、成果利用价值、经济性等特性,通过比较分析,得出相应结论:三种测绘技术在全面数据采集过程中,各有优势,都无法相互取代,在技术选择及应用中,需要结合文物建筑的价值特征进行判断、组合,做到空间信息、图案纹理信息、构造细部信息的综合采集。

A comprehensive surveying and mapping project for the east side hall of the Hall of Mental Cultivation(Yangxin dian)in the Palace Museum was introduced in this paper.This work,as a case study of the basic surveying and mapping project for research-based protection of the Palace of Prolonging Happiness(Yanxi gong),the space,texture,shape and character information of the east side hall were comprehensively collected by three Dimensional(3D)laser scanning,close-range photogrammetry and traditional manual measurement.Furthermore,for the research-based protection purpose,the above three surveying and mapping measurements were evaluated from the aspects of applicability,supportability,efficiency,utility value of project output,economy and so on.It showed that all the measurements had their own advantages thus cannot be thoroughly replaced by each other.Therefore,to collect spatial,texture and other detailed information comprehensively,it is necessary to combine all these methods in practical work.
