二次插值法在传感器数据处理中的应用

The Application of Quadratic Interpolation in Sensor Data Processing

文章在分析传统的传感器数据处理方法的基础上,给出一种基于二次插值的数据处理方法。用抛物线近似代替区间里的实际曲线,拟合精度与线性插值法相比有很大提高,同时节省了表格数据存储空间。这种处理方式具有精度高,编程简单,易于计算机实现等优点。

This paper puts forward a sensor data processing method on the basis of the analysis of the traditional sensor data processing method. By replacing the actual curve in the sector with parabola approximately, the fitting precision is highly improved compared with the linear interpolation. It can also save the form data storage space. This method has many advantages such as high accuracy, simple programming and easy to computer implementation.
