全景图像拼接算法的研究与实现

全景图像拼接算法的研究与实现 摘 要 本文在比较虚拟现实中全景图拼接的原有算法的基础上，提出了一种新的匹配算法。该算法利用较少的点来搜索较为粗略的匹配位置，然后在这不很精确的匹配点附近利用较多的点搜索较为精确的匹配位置。实验证明，该算法比原有的算法匹配速度更快，效果更好。 关键词 虚拟现实；图像匹配；图像拼接；点阵匹配 LATTICE MATCHING ALGORITHM OF PANORAMIC IMAGE STITCHING Liu Gang Yao Quanzhu Xi’an University of Technology Abstract The paper brings forward a new image stitching method in compare with former method in creating cylindrical panoramic image in virtual reality. This method search rough matching position by fewer points, and then search more precise matching position by more points in the neighbor of rough matching position. The speed and effect of image matching through this method is higher than former method from the experiment. Keywords Virtual reality; image matching; image stitching; lattice matching
