基于新型测绘技术与BIM融合的建筑文化遗产数字化应用研究

Research on the Digital Application of Architectural Cultural Heritage based on the Integration of New Surveying and Mapping Technology and BIM

传统的建筑遗产数据采集方式主要以手绘图纸、文字描述、拍摄照片、录制音、视频为主,主观性强,效率低下,误差范围大。随着三维激光扫描、摄影测量、无人机航摄等测绘技术的不断发展,为建筑遗产保护的数字化信息采集提供了多条链路。所得成果也不再使用CAD绘制二维图形,而是融合BIM平台建立数字化、信息化模型,不仅高效直观,而且可以建立预防性保护措施,实现历史建筑的全生命周期管理,更可以结合VR技术,实现虚拟重建和三维实景漫游,为大众提供更真实更沉浸式的建筑遗产感知方式。

Traditional data collection methods mainly use hand-drawn drawings,texts,photos,audio and video recordings,which are highly subjective,inefficient and have a large error range.With the continuous development of surveying and mapping technologies such as three-dimensional laser scanning,photogrammetry,and drone aerial photography,multiple links have been provided for digital information collection for architectural heritage protection.The results can no longer be drawn by using CAD to two-dimensional graphics,but can be integrated with the BIM platform to establish digital and information-based models.This is not only more efficient and intuitive,but also can establish preventive protection measures and accomplish the full life cycle of historical buildings for management,the model can be combined with VR technology to achieve virtual reconstruction and three-dimensional real-scene roaming,providing the public with a more realistic and immersive way to perceive architectural heritage.
