A chromokeying panel for use in conjunction with a chromakeying system
includes a plurality of first and second location. Each of the first and
the second locations has a color within the color of a color keying
spectrum of the chromakeying system. In addition, each of the first and
the second locations are arranged to define a coded pattern for a
computation of a perspective of the chromakeying panel with respect to a
camera independently in each video field produced by the camera. The coded
pattern may include a plurality of straight lines that intersect to define
vertices. The plurality of straight lines may be spaced apart from each
other so that for a given vertex, a ratio of the distance of one of the
lines extending from the given vertex to a first adjacent vertex, to the
distance of another of the lines from the given vertex to a second
adjacent vertex is unique.
