为消除基于深度图像绘制（DIBR）技术生成目标图像时可能出现的“褶皱”现象，提出了一种通过视图判定来确定参考图像像素点扫描顺序的方法．首先设定极点的z坐标为一个无穷小量，然后由该极点的齐次坐标得出绘制左、右视图时参考图像像素点的扫描顺序．该方法只需判断目标图像是左视网还是右视网，便可确定参考图像像素点的扫描顺序．试验表明，该方法能消除褶皱现象，且复杂度比Z—buffer算法小，适用于虚拟视点水平移动时的虚拟视图绘制．

英文摘要：

＂Folds＂ may appear when the depth-image-based rendering （DIBR） technique is used to generate destination image. In order to remove the folds, an approach to determine the scan order of reference image by view judgment is proposed. First, the z coordinate of epipole is set as an infinitesimal, then the scan order of reference image rendering the left or the right view is determined by the new homogeneous coordinates of epipole. Accordingly, the scan order of reference image can be determined by the destination image which is left view or right view. Experimental results show that the proposed approach can eliminate folds with less complexity in contrast to the Z-buffer algorithm, and it is adaptable to virtual view rendering when the virtual viewpoint shifts horizontally.
