摘　　要：讨论了B样条基本理论及应用B样条曲线进行曲面重建的理论,在车身逆向设计的实例当中,从汽车发动机盖点云数据的获取及其处理,在应用B样条生成网格曲线以及重建曲面几个方面,给出了曲面重建的具体方法,并得到了较为满意的结果。The basic theory of B - spine is discussed in the paper. The theory and method of curve and surface rebuild based B - spine is given.In the example of inverse design of bodywork, the detail method of curve and surface rebuild is given including the method of getting and dealing with automobile engine cover point cloud data, building gridding curve and surface rebuilding based on B- spine. The gratifying result of surface rebuild is obtained.
