According to the character of the high meteorological detecting data, this paper uses the non-uniform B-spline curve fitting with genetic algorithm to calculate the node vectors, and proposes the optimizing method for creating the chromosome to accelerate the convergence of the algorithm. We establish the non-uniform B-spline curve with less control points which can fit the meteorological detecting...
In according with the character of the large number and complex and unpredicted trend on change of the meteorological detecting data, the piecewise curve fitting method based on the least squares of orthogonal polynomial for scattered data is presented. Firstly, the reason of using the least squares of orthogonal polynomial for scattered data is introduced from the respect of the stability of data...
