I have 3 points in a 3D space of which I know the exact locations. Suppose they are: (x0,y0,z0)
, (x1,y1,z1)
and (x2,y2,z2)
.

Your camera has (at least) 7 degrees of freedom - 3 for position, 3 for orientation and 1 for FOV. I'm sure someone will correct me if I'm wrong, but it doesn't seem like 3 points are enough for a full solution.
For a generalised solution to this problem, look up 'View Correlation' in Graphics Gems II.
