GENERAL ORIENTATION PROBLEM OF PHOTOGRAPHS WITH PLANAR OBJECTS.

The orientation problem of photographs taken of planar objects can be treated as a special case for that of a three-dimensional object space. Based on this concept, this paper derived an orientation theory for a two-dimensional object space where the geometry of a picture can, in general, be determined by eight independent central projective parameters. First, the relationship between an object plane and its picture was explored in different ways. Then, the characteristics of the orientation problem were clarified for a stereopair of photographs and for multiple pictures overlapped. The orientation calculation was formulated algebraically with the DLT approach.
