摘要
目的改进基于径向基函数的曲面重建算法。方法针对数据量过大,无法在中低端计算机上进行曲面重建的问题,采用分而治之的思想,将点云曲面先分割后重建。结果所给方法能够明显提高曲面重建效率,实现了在中低端计算机上的曲面重建。结论对于不规则的待重建物体,使用任意方向的包围盒比使用轴向包围盒能更好地降低重建过程中的运算次数。
Aim To improve the surface reconstruction algorithm based on radical basis function （RBF）. Methods Due to the amount of data is too large, surface reconstruction can not be done in the low-end computers, hence by following ＂dividing and conquering＂ thoughts, the point cloud surfaces are firstly split, and then rebuilt. Results The presented method can obviously improve the efficiency of surface reconstruction and realize the surface recon- struction on small and medium size computers. Conclusion For the irregular object to be reconstructed, the use of the bounding box of any direction can better reduce the number of operations than the use of axial bounding box in the reconstruction process.
