摘　　要：在数字化时代背景下,科技水平得到飞跃式提升,增强现实(Augmented Reality,AR)技术在各行业领域得到广泛应用。大量地搜集相关资料,整理数字三维虚拟全景技术在新闻类影像中的具体应用实践,对基于AR技术的数字化三维虚拟全景新闻影像展开探索。引入尺度不变特征转换(Scale-Invariant Feature Transform,SIFT)方法对影像初始特征点提取后,利用动态规划算法计算影像最优缝合线,通过融合,可获得数字化虚拟三维影像。在三维注册算法标识下,对全景三维影像进行叠加,最终获得虚拟全景三维增强显示。实践证明,利用此技术,可以减少提取特征点所用耗时、增加提取影像特征点的数量,且保证特征点匹配的准确率,因此,此技术用于数字三维虚拟全景新闻影像实践有着良好前景。Under the background of the digital era,the level of science and technology h has made a leap forward,and Augmented Reality(AR)technology is widely used in various industries.This paper collects a large number of relevant materials,sorts out the specific application practice of digital 3D virtual panorama technology in news im⁃ages,and explores the digital 3D virtual panorama news images based on AR technology.After the Scale-Invariant Feature Transform(SIFT)method is introduced to extract the initial feature points of the image,the optimal suture line of the image is calculated by the dynamic programming algorithm,and the digital virtual 3D image can be ob⁃tained through fusion.Under the identification of 3D registration algorithm,the panoramic 3D image is superim⁃posed,and finally the virtual panoramic 3D enhanced display is obtained.Practice has proved that using this technol⁃ogy can reduce the time spent in extracting feature points,increase the number of feature points extracted,and en⁃sure the accuracy of feature points matching.Therefore,this technology has a good prospect for the practical use in digital 3D virtual panoramic news image.
