无人机遥感在大型不可移动文物三维重建中的应用

针对大型不可移动文物三维重建技术存在的困难,本文基于无人机遥感等平台,利用基于图片的三维重建技术,设计了一种低成本、简便高效、较高精度的大型不可移动文物的表面精细几何纹理获取与三维重建的技术流程,对建模中的技术问题进行了研究,并对其精度和实用性进行了评价。其结果较好地满足了文物测量的精度要求;为文物保护与展示等研究提供了新的思路,能全方位、近距离面向公众做三维展示;结果带有精确的地理位置信息,可作为三维GIS平台新的数据采集方法和数据源。

UAV RS Applied in 3D Reconstruction of Huge Immovable Cultural Relics

Aiming at the problem in 3D reconstruction of huge immovable cultural relics,based on UAV RS platform,we use 3D reconstruction based on pictures technique,then design a low cost,quick,high accuracy process for surface exquisite geometry and texture data acquisition and 3D reconstruction.Besides,we research on the problems in this process and evaluate its accuracy and practicability.It shows that the method meets the accuracy requirements of cultural rclics surveying,and we raise a new view for protection and display of cultural relics which can show culturals to audiences totally and closely the 3D reconstruction result has accurate position so it can be used as new data acquisition method and data source of 3D GIS platform.
