 Summary

Every triangle in 3d space have just one perspective projection on a plane. And vice versa.
We can get just one real triangle in 3d space by projection on plane.
I solve linear equation for getting rotation and position of triangle without rotation and translation matrix. And try it. Just need a AB, BC, AC lenght.
Somebody do this before?
This is demonstration with camera canon eos 600d. But I don't solve lens distortion yet.
