    摘要: Apparatus for automatic replacement of a billboard in a video image is provided. The billboard comprises a chroma-key surface, and the apparatus includes a video camera for viewing the billboard, and a chroma-key unit operative to detect at least one chroma-key color of the billboard chroma-key surface. A reference color of the chroma-key unit is adjustable to conform to the color of the chrom-key surface, thereby enabling the chroma-key unit to correctly identify the billboard surface and to correctly replace the chroma-key surface of the billboard by a virtual advertisement in a video image with correct occlusion of any foreground object.

    摘要: 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.

    摘要: A chromokeying system includes a store that contains a representation of a known coded chromokeying pattern. The system further includes a frame grabber that grabs a video image including at least a portion of the known coded chromokeying pattern and a foreground subject. A perspective transformation computation unit computes a perspective transformation by comparing the video image of the portion of the coded chromokeying pattern with the known chromokeying pattern. The system may further include a background generation unit that receives a background image and applies the perspective transformation to the background image to produce a transformed background. The portion of the coded chromokeying pattern in the video image can then be replaced by the transformed background to create a composite image.
