来自不同点的云数据的初步四次表面提取

PRIMITIVE QUADRIC SURFACE EXTRACTION FROM UNORGANIZED POINT CLOUD DATA
摘要：
A method, apparatus, system, article of manufacture, and data structure provide the ability to extract a primitive quadric surface from point cloud data. Point cloud data is obtained in 3D space. The point cloud data is segmented to create a disjoined surface and a smooth surface segment based on spatial connectivity and surface smoothness. One or more shapes are extracted from the point cloud data using geometric fitting. The geometric fitting searches for one or more quadric surface parameters of a given type of model that provides a best agreement between selected points from the point cloud data and a resultant model.

方法，装置，系统，制品和数据结构提供从点云数据中提取原始二次曲面的能力。 点云数据在3D空间中获得。 点云数据被分割以基于空间连通性和表面平滑度创建分离的表面和平滑的表面段。 使用几何拟合从点云数据中提取一个或多个形状。 几何拟合搜索给定类型的模型的一个或多个二次曲面参数，其提供来自点云数据的所选点与最终模型之间的最佳一致性。
