【摘要】 文章简述了医学图像三维重建表面绘制的基本原理,详细介绍了轮廓线连接法表面绘制的实现方法。其中边缘提取采用梯度算子和Kirsch算子结合的方法,解决了不连续边缘点连接的问题;轮廓连接采用同步前进法,并对同步准则作了改进,以解决相邻轮廓线上点的错位连接问题,重建效果较为满意。更多还原

【Abstract】 The realization of surface rending using Contour Connection Algorithm is introduced in this paper.Grads op-erator and Kirsch operator are combined on edge detect to deal with the connection of discontinuous edge point.The synchronous moving method is used on contour connection.The synchronous rule is improved to solve the problem of points oblique connection on contiguous contours.更多还原
