摘要: 古木建筑具有极高的价值,科学认识其损伤现状,并对损伤进行直观表达与信息 自动集成,有利于更好地进行文化传承。尽管建筑遗产信息模型(HBIM)技术具有模型与信息高 度关联的特点,可将信息整合至模型中,与古建筑信息表达集成需求高度契合,但在应用方面 仍存在部分难题,如损伤模型表达精细度划分,损伤信息量庞大难以快速集成。本文以古木建 筑裂缝损伤为例,首先建议了裂缝模型多细节层次(LoD)表达标准;然后分析了 HBIM 的信息 集成方式,其在 Revit 软件中以电子列表方式管理构件信息;为解决信息量大的难题,对软件 进行二次开发编写外部命令,加载成为外部应用实现信息自动集成更新;最后以一古木建筑 HBIM 模型进行方法验证,4 s 内完成了 64 根柱子的信息自动化集成。表明了裂缝多 LoD 表达 方法与信息自动集成算法的高效性与可靠性,可为历史建筑信息的表达、集成与管理提供方法 借鉴。

Abstract: The ancient wooden building is fairly valuable. Scientific understanding, intuitive expression and automatic information integration of the damage are conducive to better cultural inheritance. Although historic building information modeling (HBIM) technology has the characteristics of high correlation between model and information, and it can integrate information into the model, which is highly compatible with the requirements of the information expression integration of ancient buildings, there are still some problems in application, such as the fine division of damage model expression and the difficulty of the quick integration of a large amount of damage information. This paper takes the crack damage of ancient wooden buildings as an example. Firstly, the multi-Level of Detail (LoD) expression standard of crack model was proposed. Then, the information integration method of HBIM was analyzed in detail, that is, the component information is managed by electronic list in Revit. In order to solve the problem of the large amount of information, the secondary development of Revit was carried out by writing external commands and the software was loaded as an external application to automatically integrate and update information. Finally, the method was verified by an HBIM model of an ancient wooden building, and the automatic information integration of 64 pillars was completed within 4 seconds. It shows the efficiency and reliability of the multi-LoD expression method and information automatic integration algorithm, which can provide reference for the expression, integration and management of the information of historical buildings.
