基于照片的三维重建技术研究

Research on 3-D Photo Reconstruction Technology

古代文化遗址是研究古代历史文化、艺术和科学技术发展的极其重要的实物资料.在各种研究技术方面,基于二维照片的三维重建技术由于其突出的优势已经越来越受到人们的关注.文章主要从基于二维照片的三维立体配准方面展开研究与讨论,通过特征点的提取、立体匹配和空间点三角化,实现场景的三维重建.唐小雁塔的实验结果验证了其可用性.

The ancient cultural site is a very important kind of information in the study of ancient history, culture, art and sci- ence and technology development. Due to its higher advantage, 3-D reconstruction technology which is based on 2-D photo has been taken increasingly much attention. This paper mainly discusses 3-D stereo matching based on the 2-D photo, by extraction 3-D fea- ture point from 2-D photo, the stereo matching and the spatial point of the triangle to achieve 3-D reconstruction. Experimental re- sults in Small Wild Goose Pagoda of Tan~ dvnastv verify th~ availability.
