How do I find the world coordinates of a pixel on the image plane?

我怎么才能找到世界的图像平面上的像素坐标？

So the idea of spherical coordinate is you're going to polar coordinates again in the rz plane.

所以说球坐标系,其实就是在rz平面再建立一个极坐标。

Prove some inequalities involving a moving-point on the plane of triangle with it′s distance coordinates.

利用三角形的重心坐标，证明涉及三角形平面上一动点的一些不等式。
