摘　　要：针对工业CT层间图像变化较大的特点,提出一种基于距离变换的非线性插值方法,该方法利用目标边界上像素的膨胀或腐蚀运算,使目标形状从一幅ICT图像向另一幅均匀变化,并给出了该插值方法应用于工业CT图像的形状插值结果。Owing to the great difference between the industrial CT slices, this paper proposes a method of nonlinear interpolation based on the distance transformation, through using the dilating or eroding operation on the object boundary, which makes the object shape well-proportioned changed from one slice to another. At the end of the paper we present the results of the experiments with industrial CT pictures.
