摘要：
The reservation of shape features is the key problem of filling hole. In this paper, we present a hole filling method based on feature lines, including the hole boundary lines, ridge lines and valley lines. First, the feature lines are extracted and used to generate a series of curves. Then the control points sequence is obtained by fitting these curves. Finally, the NURBS surface is fitted by control points sequence to fill the hole. The obtained results show that our method can preserve the initial shape characteristics of hole.
