基于建成遗产测绘技术的京奉铁路辽宁总站建模研究OA

Taking Liaoning Terminal of Peking-Mudken Railway in Shenyang as the research object,this paper explores how to build a digital model for the built heritage with high credibility under the constraint of unavailable on-site survey by using multi-source historical data.By systematically integrating Yang Tingbao's original drawings,scholarly literature,and historical and contemporary imagery,a three-tier credibility framework for source materials is established based on authority and verifiability.This framework is further refined into a six-level classification of model data credibility by incorporating measurement,calculation,and proportional estimation methods.Pseudocolor visualization is employed to represent the building components according to their credibility levels,balancing both authenticity of the model and academic rigor.
