Abstract The characteristic of acquired measurement data in the production line is analyzed.Then,a weighted iteration smooth filter method using dispersion of measurement points to optimize the weights is described.Compared with average filter method and median filter method,the method can eliminate the noise information in the on-line measurement points more effectively and better signal to noise ratio.
