Abstract
A virtual viewpoint synthesis method and system, including: establishing a left viewpoint virtual view and a right viewpoint virtual view; searching for a candidate pixel in a reference view, and marking a pixel block in which the candidate pixel is not found as a hole point; ranking the found candidate pixels according to depth, and successively calculating a foreground coefficient and a background coefficient for performing weighted summation; enlarging the hole-point regions of the left viewpoint virtual view and/or the right viewpoint virtual view in the direction of the background to remove a ghost pixel; performing viewpoint synthesis on the left viewpoint virtual view and the right viewpoint virtual view; and filling the hole-points of a composite image.
