| 摘 要： | 本文利用小波阈值降噪方法对高层建筑物GPS动态变形监测数据进行处理,针对不同小波基选取对结果影响进行了实验分析,表明小波变换可实现高层建筑物GPS动态监测数据的有效去噪,可克服传统处理技术对非平稳、非等时间间隔观测数据序列滤波的局限性,为监测数据的处理方法提供一定参考。

| Abstract: | This paper processed the GPS dynamic deformation monitoring data of high-rise buildings by the means of threshold de-noising method of wavelet,and carried out the comprehensive experimental analysis about the impact on the results with different wavelet bases selected,which shows that wavelet transform could de-noise effectively for the GPS dynamic monitoring data of high-rise building,and diminish the limitations of filtering for non-stationary and non-equal time interval observation data sequence in traditional processing techniques.And it could provide a reference for the processing of monitoring data. |
