贴近摄影测量与BIM技术在濒危民族建筑部件级实景三维建设中的应用

为完善我国传统村落实景三维建设，并传承和保护传统村落濒危民族建筑，本文以广西传统村落部件级实景三维建设工程为依托，首先利用倾斜摄影测量技术对传统村落进行城市级实景三维建模，利用贴近摄影测量技术与BIM技术对濒危等级高的民族建筑进行部件级实景三维建模；然后将倾斜摄影技术建模与贴近摄影测量技术建模的模型相融合，形成传统村落部件级实景三维模型图；最后根据濒危民族建筑构件的外观特征、尺寸信息、濒危等级、所处年代、地理位置，利用BIM技术对其进行参数化建模、编码与入库，形成可查询的实景三维模型数据库。

Application of close to photogrammetry and BIM technology in component level 3D real scene construction of endangered ethnic buildings

In order to improve and perfect the 3D real scene of traditional villages so as to achieve the purpose of inheriting and protecting the endangered ethnic buildings in traditional villages. Relying on the component level 3D real scene project of traditional villages in Guangxi, this paper uses the oblique photogrammetry to build the urban level 3D real scene of traditional villages, and uses the close photogrammetry and BIM to build the component level 3D real scene model of highly endangered ethnic buildings. The component level 3D real model map of traditional villages is a combination of oblique photography model and close photogrammetric model. According to the relevant information of the endangered ethnic buildings, including the appearance characteristics of the components, size information, endangered level, age and geographical location, this paper uses BIM technology to carry out parametric modeling, coding and warehousing, forming a searchable 3D real model database.
