Metric Rectification for Perspective Images of Planes

It is well known that under perspective imaging a plane is mapped to the image by a plane projective transformation (a homography) [13]. This transformation is used in many areas of computer vision including planar object recogni-tion [12], mosaicing [15], and photogrammetry [14]. The projective transformation is determined uniquely if the Eu-

E. L. Elte identified it in 1912 as a semiregular polytope, labeling it as S 1 8.It is also called 0 6,1 for its branching Coxeter-Dynkin diagram, shown as .. Coordinates. The Cartesian coordinates of the vertices of the rectified 8-simplex can be most simply positioned in 9-space as permutations of (0,0,0,0,0,0,0,1,1). This construction is based on facets of the rectified 9-orthoplex.

Image rectification - Wikipedia

Image rectification is a transformation process used to project images onto a common image plane. This process has several degrees of freedom and there are many strategies for transforming images to the common plane. It is used in computer stereo vision to simplify the problem of finding matching points between images (i.e. the correspondence problem).
