中文摘要： 建筑遗产调查需要综合三维测绘及物理环境采样两种成果，以准确评价其保存现状并科学分析破坏成因与发展趋势，辅助遗产保护设计工作。我国建筑遗产不仅尺度大，而且地形环境复杂，因此两种勘测工作普遍受到干扰，导致数据不全。上游学科对此亦缺乏专门研究成果，因此一直是外业主要难题。本课题基于低空-地面综合信息采集技术，解决测绘和物理环境监测中的两个关键问题：一、复杂环境下建筑遗产内外空间的完整测绘；二、微地形物理数据低空矩阵化获取。拟通过实施一定数量实验，总结复杂环境下低空勘测的优化实施策略，填补本领域利用的方法缺环，满足我国各地域多种类型遗产调查的需求。 在数据处理和利用方面，本课题将三维测绘模型与三维矩阵化分布的多源环境数据准确匹配、融合，获得三维可视化的微地形-环境数据，输入环境模拟软件预测遗产变化趋势，最后尝试实施低空信息技术辅助的遗产保护设计和验证，构建较完整的遗产信息工作流程。

英文摘要： The survey of architectural heritages requires complete 3D mapping results and environmental data, which help us to evaluate the status quo of their preservation, analyze the causes of damage and tendency of changes, and assist us in heritage conservation planning and design. Chinese architectural heritages are usually large in scale and great in number and are usually located in complex environment, which poses a great challenge for field work like mapping and physical data sampling. Based on low-altitude information acquisition technology and some ground-based means, the project is to address two key problems in mapping and physical environment monitoring: 1. complete mapping of the interior and exterior space of architectural heritages in complex environment; 2. Spatial-matrix acquisition of the physical data of micro-topography. We intend, through a certain number of experiments, to summarize the operational methods for different classes of architectural heritages and environments, in the hope of filling the gap in the new low-altitude technology and meeting the needs of surveying various types of heritages on various terrains. In terms of data processing and use, we attempt to accurately match and integrate the 3D mapping model and multi-source environmental data; to obtain 3D-matrix environmental analysis results and the visualized assessment data of multi-source coupling status. Then we will compare real data with simulated data obtained from environmental software and try multiple-IT-assisted heritage protection design to verify the practicability of air-ground integration, which is the result of our heritage surveying and monitoring research.
