摘要
提出了基于Matlab的任意闭合型值点的一维三次样条插值方法,并应用于闭曲面的三维重建中。首先对物体进行360°扫描测量,获得物体表面三维条形图。经过曲面切片、型值点提取、点列排序、一维插值、数据融合,得到闭曲面四边形网格图。给出了完整的基于Matlab的算法描述,并通过三维重建实例,验证了方法的有效性和可行性。
The 1D 3-ordered spline interpolation method for arbitrary closed offset points based on Matlab was put forward, and has been applied to 3D reconstruction of closed surfaces. Firstly, a 360°rotational scanning measurement was conducted upon the object to obtain the 3D strip profiles of object surface. The quadrilateral grid graph of closed surfaces was obtained through surface slicing, offset point picking up, ordering of point array, 1D interpolation, and data merging. The description of complete algorithm based on Matlab has been presented, and by means of a living example of 3D reconstruction verified the effectiveness and feasibility of this method.
