Photogrammetric Observation of a Rectangular Parallelepiped 
The straight line IL model can be extended to observe compound features such as a 
rectangular parallelepiped { C, ft, 0 2 , r x ,r 2 , r 3 }: 
An experimental photogrammetric relationship of the rectangular parallelepiped can be 
represented by an equation of the form: 
*L| |p UPi + bfi 2 + c&t *£ 2 ) ((C-L) + d,r,P|+eir 2 p 2 +/,r 3 p 1 xp 2 )|-0
