3D B-Spline Surface Reconstruction Based onthe Contour Information

摘要：

This paper introduces a 3D surface reconstruction method from serial parallel slices of cross-sections.Depends on the contour shape we get a series of regular points.The density of the points reflects the change of the contour shape,and then corresponding knot vectors and control points are generated from these points.Define a flexible space to compute the knot vector of the surface.For the multi-connectivity problem,using image division translates it into some single-connectivity problem. The centroid of each slice and each closed contour is generated to get the relationship of the contours.So,the many-to-many question translates into some one-to-one question.
