We consider the problem of matching perspective views of coplanar
structures composed of line segments. Both
model-to-image and image-to-image correspondence matching
are given a consistent treatment. These matching scenarios
generally require discovery of an eight parameter projective
mapping. However, when the horizon line of the object plane can be
found in the image, done here using vanishing point analysis,
these problems reduce to a simpler six parameter affine matching
problem. When the intrinsic lens parameters of the camera
are known, the problem further reduces to four parameter
affine similarity matching.
