【摘要】 针对实际中全向视觉的畸变图像,介绍了如何合理的处理全景摄像头拍摄的实际图像及构建正常图像的必要性。研究了单视点全景视觉成像系统的限制条件,再而提出了全景图的圆柱面展开形式,讨论并实现了两种不同的插值算法,同时计算完成了双曲面反射镜的拟合公式并最终通过带有CCD摄像头和双曲面反射镜的机器车实现。结果表明,图柱面展开法在显示目标信息方面优于全景图像,且更有利于进一步目标识别的实现,同时非常简洁与方便。更多还原

【Abstract】 Aiming at distort images caused by panoramic vision in real life,how to deal with distort images and the necessary of construct-ing normal images are introduced.The limitation of single point image system and the method of cylindrical image unfolding are come up.Then,two different methods of interpolation are discussed and realized.At the same time,the fitting formula of hyperboloid mirror is ac-complished by calculating.The experiment is finally verified by machine car equipped with both CCD camera and hyperboloid mirror.The result shows that the method of cylindrical Image is superior to panoramic image on the showing target information,and conducive to the realization of further target identification.Besides,it’s simple and convenient.更多还原
