摘要: 提出一种对鱼眼图像进行校正和配准的算法。首先把鱼眼图像从相等距离投影模型映射到参数化球面投影模型,使得合成球面全景图成为一个平移求解问题。然后使用非线性优化算法进行图像的配准。在合成场景的球面全景图以后,通过重投影球面全景图到视平面来完成虚拟场景的实时漫游。

Abstract:

A new algorithm is presented to realize fisheye images calibration and registration. By remapping fisheye images from equidistance model to parametric spherical model, spherical panorama creating becomes a translation problem. Nonlinear optimizing algorithm is used to do image registration. Interactive and realtime rendering can be achieved by reprojecting the spherical panorama onto the view plane.

Key words: fisheye image, image calibration, image registration, panoramic image
