在基于位置的视觉伺服中，需要建立将二维图像信息转换为三维坐标信息的图像雅可比矩阵。

In the robotic visual servo system based on the position, it is need to build an image Jacobian which transforms two-dimensional image information to three-dimensional coordinate information.

将图像转换为矢量图形，由计算机提取图形节点坐标形成二维点集矩阵。

The image is converted into vector and sketch node coordinate is withdrawn automatically by computer, two dimension the point gather the matrix is formed.

现在我们已经有了照相机，但是还要将3D空间影射到把三维空间坐标系转换到二维屏幕坐标系的“视口”上。

Now that we have the camera, we must map 3D space to a 'viewport' which handles the translation of coordinates from 3D space to the 2D screen.
