基于空地一体多源数据融合构建高精度古建筑模型

Construction of High Precision Ancient Building ModelBased on Air-ground Multi-source Data Fusion

中国古建筑具有悠久的历史传统,保护和传承古建筑也成为了目前社会的热点研究问题之一,构建古建筑的实景模型是文物保护的基础和前提。然而,近些年发展起来的基于人工、倾斜摄影测量技术、三维激光扫描等技术构建的三维模型,在古建筑建模的方法和效果上均存在诸多局限。因此,本文提出使用无人机倾斜摄影、无人机环绕摄影、近景贴近摄影等空地一体多源数据融合的方式,实现全方位、无死角的三维模型重建,为获得低成本、高效率、高质量的精细化古建筑模型提供相应理论与技术指导。

Chinese ancient buildings have a long historical tradition.The protection and inheritance of ancient buildings has also become one of the hot research issues in the current society.The construction of a real-life model of ancient buildings is the basis and premise of cultural relics protection.However,the three-dimensional model based on artificial,oblique photogrammetry technology and three-dimensional laser scanning technology developed in recent years has many limitations in the method and effect of ancient building modeling.Therefore,this paper proposes the use of UAV oblique photography,UAV surround photography,close-range photography and other air-ground integration of multi-source data fusion to achieve all-round,no dead angle of the three-dimensional model reconstruction in order to obtain low-cost,high efficiency,high-quality fine ancient building model and provide the corresponding theoretical and technical guidance.
