利用照片建模技术重建文物的三维数据模型

Three-dimensional image-based modeling for reconstruction of cultural relics

基于照片的三维建模技术是指直接通过二维数码照片来重建物体的三维数据模型。根据照片建模的基本方法和基本原理,利用该建模技术实际完成了重庆大学校内一尊塑像的三维数据模型的建立。照片建模技术在文物遭遇自然灾害或者意外事件之后的成功应用表明,文物的三维模型重建和文物保护等方面具有一定的实用价值和推广应用前景。

An image-based modeling technique is described that can reconstruct 3D models of objects directly from two-dimensional digital images.This research introduces the basic method and principles of image-based modeling.This technique was used to build a 3D model of a statue on the campus of Chongqing University.This image-based modeling technique could be used in the case of natural disasters or accidents for construction of a 3D model and,therefore,be used for the restoration of cultural relics.The technique has practical value and various potential applications.
