Hello! I would like to know if there is any way to calculate a distance based of this single point perspective drawing of a 17th century theatrical scenery :
We have this elements:
The real-life size of the object ABCD is (AB : $125$ cm ; BD : $75$ cm )
In the picture, the size of the object at the foreground is (AB : $2.5$ cm ; BD : $1.5$ cm)
In the picture, the size of the same object in the background is (A'B' : $1.16$ cm ; B'D' : $0.7$ cm)
The eye level is about $159$ cm.
The angle of the receding lines is $40^\circ$
Is it possible to evaluate the distance $d$ between the two objects in real life?
Thank you!
