How do we go from distortion to rectilinear? Is there any way to convert this based on a single image? In the distortion scene, a straight line is very hard to recognize.

I am wondering how do we actually know what parameters we should use to correct the distortion. If we know our camera well, meaning we know the parameters of the lens etc., we can calculate the correction needed to turn it into a rectilinear. But what if we have a photo that is distorted without knowing its parameters, can we still correct the photo correctly?

Also, I am wondering if this kind of correction works for every objects in the scene, meaning far and near objects are correctly "rectilinearized"? In my experience, when taking a photo on a phone, far away objects look good, but when it moves very close to the camera, it looks distorted.
