The absolute stereoscopic parallax is 10.36 mm in this case, i.e., the sum of the distances of the corresponding images from their respective nadirs. Parallax difference in this case is the difference in the absolute stereoscopic parallax at the top and base are the objects being measured i.e., 10.36–10.32 = 0.04.The difference between the absolute stereoscopic parallax at the top of the object and at the bottom of the image. It is represented customarily by the symbol dp.
