O jiO XYImage of 64 gray level Binary image。= frRz(1) Image point (2) Image Line 3D line l is projected onto image plane through projecting plane to get image line L: Let we use a vector to represent the image line L of l.Since We have, orIt is the equation of projecting plane, the normal is .Thus, we will use the normal of the projecting plane of 3D line to denote image plane by.4.
