| Abstract: | This paper analyses the uniform B-spline model with shape parameters,and applys the model to the curve fitting of discrete data points.In this paper,the value of the shape parameter is studied,and an algorithm based on iterative linear closest points is put forward to rectify the parameter values of data points.The analysis of experimental results demonstrates the validity and robustness of our algorithm. |
