I want to ask the same question as from this tread, about planar homograph but using absolute values so I can visualize it.
My goal is to retrieve 3D transformations of a plane (position/rotation related to the camera) from within a picture. I am not sure if homograph is what I need. Please correct me if not.
Here is the link for the picture I am analysing:
Lets say my points on the image plane are:
p[0] = x:407 y:253
p[1] = x:386 y:253
p[2] = x:406 y:232
p[3] = x:385 y:232
these points are in a 500px width x 333px height image plane with 0,0 at top left corner. These points represents the corners of 30mm side square contained in a picture. Assuming this picture was taken by a fixed camera at origin heading Z axis.
So, I know the physical distance between p0,p1 ; p0,p2 ; p1,p3; p2,p3 are 30mm and they are co-planar.
But is it possible to get the X,Y,Z of each point only using this information above so I can recreate the 3D plane?
EDIT* Here a link to what it seems to be a very well explained theory of what I am looking for (from page 34) I can't follow it very well however...
ps: Moderator, excuse me. I am not sure if I should post a new tread or extend the question on the previous tread. Please feel free to delete this tread if necessary.
