Fisheye lens; stereo vision; epipolar rectification; 3D reconstruction; image stitching;

鱼眼镜头；立体视觉；极线校正；三维重建；图像拼接；

The results show that fisheye menu has advantages in some aspects.

比较结果表明，鱼眼菜单在很多方面具有一定的优势。

Corresponds to a fisheye lens, and a large value to a telephoto lens.

输入照相机的焦距。小焦距值对应“鱼眼”镜头，大焦距值对应远射镜头。

Then we transform the fisheye image of 180 degree to normal perspective image.

再用一种简单的数学模型即球面投影，实现了180度鱼眼图像的还原。
