I would like to derive an expression for an Epipolar Line that appears in a right camera (there are two cameras - a left a right one). These cameras are placed in a $(x,y,z)$ vector space. This is a past paper for my computer vision course.
Left camera position = $[-10,0,0]$
Right camera position = $[10,10,0]$
Both of the cameras are facing the same direction of $[0,0,1]$
Their plane of projection lies in the plane $z=10$
An object has position $[x_{i},y_{i},z_{i}]$
If I could find out how to derive an expression for this line then I'm sure I could derive similar expressions for different camera positions etc. It would be a great help if someone could work through this with me.
Thanks in advance.
