本文针对三维人脑计算机图谱问题 ,采用线性插值算法 ,给出了一种可用于序列图象的高精度表面重建的层间轮廓线插值方法 .该方法不仅对一般问题的效果良好 ,而且成功地解决了弹性插值中不能解决的示例 .对一系列数据的实验结果表明 ,它是一种可行的层间轮廓线插值方法 ,对医学影像数据的三维重建和显示具有重要意义 In this paper, aiming at the problem of three-dimensional human brain computer graph, a linear interpolation algorithm is used to interpolate the contour of contour line which can be used for high-precision surface reconstruction of sequence images. The method not only works well for general problems, but also successfully Which solves the problem that can not be solved in elastic interpolation.Experimental results on a series of data show that it is a feasible interpolation method of interlayer contour and is of great significance to the reconstruction and display of medical image data in three dimensions
