摘要
点云配准是三维建模过程中的关键问题之一,快速高精度的配准是点云配准研究的重点。提出了一种利用独立成分分析(ICA)的点云配准方法,通过对两组点云数据作ICA,得到其独立分量、混合矩阵,以及解混合矩阵。由于ICA存在模糊问题,两点云的独立分量可能存在顺序和符号上的差异,在F范数最小的优化准则下可以得到两独立分量的最优变换矩阵。进一步,根据点云数据与独立分量之间的关系,实现点云的精确配准。实验结果表明,该算法配准速度快,具有较高的配准精度。
Abstract
Point cloud registration is one of the key issues in the process of three-dimensional modeling. Fast and high precision registration is the focus of point cloud registration. A method of point cloud registration based on independent component analysis (ICA) is proposed. The independent components, mixing matrix and unmixing matrix are obtained after ICA of two point cloud. Because of the fuzzy problem of ICA, the independent components of the two point cloud may have the difference in the order and the symbol. The optimal transformation matrix of two independent components can be obtained under the optimization criterion of minimum F norm. Further, the accurate registration of point clouds is achieved based on the relationship between point cloud data and independent components. Experimental results show that the proposed algorithm has faster registration speed and higher registration accuracy.
