How to calculate the real size of an object from two photos in different types of perspective, knowing the dimensions of one of the objects in these pictures?
When I was in college, we did such calculations but it was a long time ago and I have no records. From what I remember,We need the coordinates of a known object from both photographs and the coordinates of the object searched from both photographs. And the realdimensions of the known object.
Is anyone able to give a formula how to calculate it?
