摘要: 针对高空气象探测数据变化规律复杂、突变情况不可预测、数据量大等特点,采用基于遗传算法确定节点矢量的B样条曲线拟合方法,并提出优化染色体的产生方式,加速算法的收敛效率,实现了在给定误差要求下,用较少控制点的B样条曲线拟合高空气象探测数据曲线,并通过对气温-高度曲线特征点的拟合效果证明了算法的可行性。

Abstract: According to the character of the large number and complex and unpredicted trend on change of the meteorological detecting data,this paper uses the B-spline curve fitting with genetic algorithm to calculate the knots,proposes the method of optimizing the creation of chromosome to improve the converging efficiency,realizes that the B-spline curve with less control point can fit the meteorological detecting data curve,and the validity has been proved by the result of fitting the feature point from temperature-height curve.
