  • The picture almost fits my screen which is nowhere near $75\text{ cm }$ in height. – Git Gud Oct 10 '13 at 20:09
  • @GitGud: I think the real table is supposed to be $75$cm high – Henry Oct 10 '13 at 20:11
  • Yes ist hight of real table. – Majlik Oct 10 '13 at 20:13
  • I think it should take into account all abberations and distortions introduced by the fact that the camera lens is spherical, not perfect, etc. The image is neither an isometry, apparently, nor it preserves parallel lines. – TZakrevskiy Oct 10 '13 at 20:21
