基于Remake的三维建模技术在摩崖石刻数字化重建中的应用

由于长期暴露于自然环境中,许多摩崖石刻在日晒雨淋、风沙磨蚀等多种因素作用下不断风化,前景堪忧。因此,当务之急是采取有效的措施保护和保存这类珍贵的文化遗产。数字化三维重建技术能够完整地保存石刻现状,为日后的维护、修复和学术研究提供真实、详尽的科学依据。基于Remake三维建模技术的方法与特点,本工作探讨该技术在摩崖石刻数字化重建中的应用。以广西桂林"桂海碑林"内的石刻为研究对象,运用Remake软件对数字相机获取的数字影像进行处理,对摩崖石刻进行快速精确的逆向建模。同时,将三维扫描仪获取的点云数据与本研究获取的模型数据进行同名点精度检测,分析Remake三维重建的精度。三维模型数据可以作为数字档案进行存档和展示,加强对摩崖石刻类文物的保护措施,具有重要的意义。

Application of Remake-based 3D modeling technology to digital reconstruction of cliff carvings

This article introduces the methods and characteristics of 3D modeling technology based on Remake software and explores the application of this technology to digital reconstruction of cliff carvings. We selected the Guihai Forest of Steles, which is located in Guilin, Guangxi, as our research object. Remake software was used to process the image obtained by the digital shooting equipment and to conduct the quick and accurate reverse modeling of cliff carvings. Then the accuracy of 3D Remake reconstruction was analyzed according to the accurate verification of the feature points of the point cloud data acquired by the 3D scanner and the data acquired by this method.The 3D model data could be saved and exhibited as digital archives which have great significance for enhancing the protection measures for cliff carvings.
