MPU算法在汽车车身造型设计中的应用

APPLICATION OF MPU ALGORITHM TO AUTOMOBILE BODY DESIGN

介绍了多层面单位分割隐函数曲面(MPU)算法。该算法建立在局部形状函数、单位分割和八叉树细分的基础上,可由点云数据快速、准确、自适应地进行曲面反求。应用该算法,对车身外覆盖件和内部结构件进行了曲面反求,结果表明,该算法对汽车车身开发具有重要的应用价值。

Multi-level Partition of Unity implicits（MPU） is introduced,which is based on local shape functions, partitions of unity and an octree hierarchy. MPU implicits are capable of providing a fast, accurate, and adaptive reconstruction of complex shapes with scattered point cloud data. The algorithm is applied to the reconstuction of the covering panels and internal structure, and the result indicate that the algorithm has important application value for the exploitation of automobile body.
