| 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. |
