Abstract： |
This invention relates to a composition method of virtual view points in an interactive video system with multiple view points, which initializes the video system to fetch the actual video frame of the current time point based on the serial number and divides the frames into foreground and background pictures. A background panoramic picture is got by the background picture and a foreground gray picture is got by the foreground picture to set up a corresponding relation with the picture characters picked up by the adjacent actual view points, then carries out triangle dividing and carries out interpolation operation between the two adjacent actual view points to get the virtual view point foreground picture to be laminated with the background panoramic picture to get the virtual view point picture. |
