I am trying to find the relation between the vertical displacement of an object to the depth of the object.
Say, there is an object in an image and as the center of gravity of this object moves vertically upwards, we know that it is moving away from the camera.
We know at the same time, that the dimension of the image would reduce because the object is moving away from the camera.
So, two things are happenning - 1 . the objects center of gravity is moving up vertically and 2. the object dimension is decreasing because the object is moving away from the camera.
Is it possible to find a relationship between "the vertical displacement of the object from one frame to another frame" and "the distance of the object from the camera from one frame to another frame" ?
