摘　　要：针对传统插值法的缺点提出了本文的方法。首先介绍了最小二乘支持向量机的原理以及线性平滑滤波,然后构造了LS-SVR滤波算子。根据滤波策略和LS-SVR的特点构造的LS-SVR卷积模板,将LS-SVR的训练过程简化为简单的加权求和运算,提高了算法的运算速度也简化了运算过程的复杂性。The paper is presented based on the deficiency of traditional interpolation. First, the theory of LS-SVR and linearity smoothness filtration are introduced, then LS-SVR filtration operator is constructed. To improve the arithmetic operation speed and simplify the arithmetic process complexity, it constructs the LS-SVR convolution mask based on the filtering strategy and LS - SVR characteristic, training process of LS-SVR is turned into simple weighted summation operation.
