Hi,

Firstly, I shall write 2 functions hom->cart and cart->hom and
Secondly, draw the transformation+projection matrix out of the blue and

Either I haven't understood the task or the ordering serves confusion . Do we have to put them in a reasonable order ourselves our is there are reason behind the ordering of to-do's ?

The first two tasks are independent to the third (load and show 2D points).

Right!

I don't understand "draw the matrix out of the blue". It seems not the task.

The data obj_2d.mat provides me with x,y points and you provided the steps that were performed on the 3D points?

I shall perform the provided operations on my 2D points and obtain my 3D points, which have the same z-values like those in obj_2d.mat, is that right?

Seems you misunderstand the question.

All the projective transformations from 3D to 2D are already given (or defined). The task is to solve an inverse problem from 2D to 3D.

The aim is to use the x,y-coordinates and perform the inverse operations?!

apply inverse projection with in/extrinsics on x,y -> add the separatly provided z coordinates, undo the remaining operations. Is that correct?

Sorry for asking so much, but I really have troubles to understand the aim here...
