摘　　要：作为历史的表征,残损佛像无法完整呈现其历史原貌和研究价值。为再现佛像原始风貌,同时为本体修复提供科学依据,本文提出一种基于三维虚拟技术的破损区域修复方法,对潼南大佛头部破损区域进行修复。首先,应用激光扫描技术和摄影测量技术,获取潼南大佛头部全方位、高精度、真实的信息数据;接着,建立头部三维模型,并在此基础上,进行修复区域几何形态的精确量算及数据分析,进而完成虚拟修复效果模型。研究结果表明,该技术提升了修复效果的准确性和可信度,可为石窟类文物数字化保护提供参考。As historical and cultural representations,damaged Buddha statues can no longer fully present their original appearance and value to the world.In order to faithfully represent the original appearance of a large but damaged Tongnan Buddha statue,and to establish a scientific basis for restoring the statue itself,this paper proposes a repair method using 3D virtual technology to restore the damaged areas of the statue’s head.Firstly,laser scanning technology and photogrammetry were utilized to acquire comprehensive,high-precision data related to the damaged area.Secondly,a 3D model of the head was constructed and used to make precise measurements of the geometric attributes within the area to be restored in order to create a virtual restoration model.The research results indicate that this technology significantly enhances the accuracy and reliability of restoration work,and provides a valuable reference for the digital conservation of cave temple relics.
