| 摘 要： | 在虚拟全景空间的构建中,360°柱面全景图象拼接是一项关键技术。该文通过对拍摄的实景图象做快速傅立叶变换,利用图象互功率谱的相位信息来实现全景图象的拼接,实验表明该方法大大提高了拼接速度,并且能够有效地克服图象间光照变化对拼接的影响,是一种快速实用的全景图拼接方法。

| Abstract: | degree cy lindrical panoramic image mosaicing is one of the key techniques in construction of virtual panoramic space.A method is proposed in this paper,which makes use of phase information of cross-power spectrum in panoramic image mosaicing by e mploying Fast Fourier Transform of images.Experiments results show that the pro posed method not only can significantly improve the speed of mosaicing,but als o can efficiently reduce negative effect introduced by the illumination variatio n between images,which is demonstrated to be a rapid and practical method. |
