摘要
采用主元分析方法检测过失误差,然后应用多尺度主元分析方法(MSPCA)滤除随机误差.仿真结果表明,这种新的数据校正方法有效地消除了测量数据中的误差,提高了测量数据的可靠性.
Based on PCA and wavelet transformation, application of MSPCA methoed in data rectification was investigated. PCA is used to detect gross errors and MSPCA is used to eliminate random errors. Simulations show the new method of data rectification can effectively eliminate errors in measured data and largely increase the reliability of measured data.
