摘要:
针对覆盖率较低的曲面配准问题,提出一种先粗配再细配的点云模型配准方法. 首先,采用基于GH-LS3D(Gauss-Helmert least-squares 3D)的配准算法实现曲面的粗配准; 然后,在迭代最近点(iterative closest point,ICP)算法中引入高斯概率模型和动态迭代系数以提高算法的抗噪性和收敛速度,由此实现曲面的快速精确细配准. 实验结果表明,该优化配准方法能够实现曲面的精确配准,并在细配准阶段取得了较高的配准精度和收敛速度,是一种有效的曲面配准方法.
Abstract:
Aiming at the registration problem of 3D point cloud data models of surfaces with low overlapping,a registration method form coarse to fine is proposed. Firstly,based on Gauss-Helmert least-squares 3D(GH-LS3D),a registration algorithm is used to complete coarse registration. Secondly,an improved iterative closest point(ICP)algorithm which integrated Gaussian probability model and active iterative coefficient to ICP algorithm is proposed to improve the anti-noise capability and convergence rate,and the faster and more accurate registration of surfaces is achieved. The experimental results show that the proposed method can complete accurate surfaces registration,and obtain higher registration accuracy and convergence rate in fine registration stage. Therefore,the optimal registration method is an effective surface registration method.
