中文摘要：

在逆向工程中,曲面重构往往涉及到一些孔洞修补问题,这些缺陷会对所建曲面的质量产生很大的影响。介绍了曲面修复技术国内外的研究现状与进展,分析了曲面修复的方法、离散点的插入以及离散点集的三角剖分等技术,明确了该领域存在的有待进一步完善的关键技术问题,为后续研究提供了基础。

英文摘要：

Surface reconstruction usually refers some holes in the process of reverse engineering,which have important impact on the quality of the reconstructed surface.It mainly introduces present re-search state and development on repair surface at home and abroad,analyzing repair method,inserting scattered vertex and triangulation of the scattered points.Key issues that need to be further solved and im-proved in the future are determined.
