It is natural to use the spherical coordinates when we consider a problem in a ball. In this case.

当我们处理球内问题时,引入球面坐标是一种合理的选择。

With used Newton s image formula of spherical refraction and the optical spacing term, the formula about cardinal point and image of the thick lens is derived with simpler and more natural way.

利用折射球面成象的牛顿公式及光学间隔概念,更加简洁地得出了有关厚透镜成象的基点及物象公式。

However , the Earth is not exactly spherical but is closer in shape to an oblate ellipsoid , a shape which bulges around the equator.

但事实上,地球表面更接近于一个扁椭球面,在赤道周围更加突出。

Our globe, however, is not even a perfect oblate spheroid, because mass is distributed unevenly within the planet.

然而,我们的这个星球,也并不是一个完全的扁球面,因为在这个行星上,物质分布不均。

The algorithm automatically adjusts every image's inserting point by mapping multi-images onto a suitable sphere, to make accumulative average gray values of difference images on overlapped position be minimal, and then conversely maps the spherical image to plan image to finally get the stitched images.

该算法通过把多幅图像映射到一个合适的球面上,自动调整每幅图像的插入点,使得重合位置的差值图像灰度累积平均值最小,然后球面的图像反映射成平面形式,最终得到拼合图像。
