Digital restoration of incomplete cultural relics based on close-range photogrammetry
摘要
Abstract
In response to the complexity of the digital restoration of incomplete cultural relics,this article adopted a close-range photogrammetry technology for the digital restoration of incomplete cultural relics and analyzed it.This method used an ordinary smartphone to combine relative static photography and relative dynamic photography to collect multi-view images of incomplete cultural relics at close range and reconstruct their three-dimensional(3D)real-life models.Then,through professional modeling software,the 3D model of the incomplete cultural relics was repaired locally and globally,and virtual reality(VR)panoramic images and point cloud data models were extracted to achieve high-precision modeling and digital restoration and protection.The digital restoration results show an average outer diameter deviation of geometric accuracy of-1.522 mm,an average inner diameter deviation of 1.343 8 mm,an average thickness deviation of 2.136 6 mm,and a standard deviation of surface smoothness of 0.002 mm.The experimental results show that this method for digital restoration and modeling has high accuracy and good effect,and the resulting digital products provide strong data support for the digital protection of cultural relics.关键词
