摘要
为克服传统小波变换的不足,采用提升小波变换法设计了能较好处理非线性问题的小波域中值滤波器,并应用于水电厂水轮机噪声监测数据融合中,对具有不同分辨率的多传感器数据进行融合,结果表明该算法有效。
In order to overcome the shortcoming of traditional wavelet transformation, the lifting wavelet transform method is proposed to fuse multi-sensors data in this paper. The Wavelet Domain Median Filter which can process nonlinear problem commendably is designed according its algorithm characteristic. The improved data fusion way is used to fuse multi-resolution data in monitoring noise of water power plant＇s hydraulic turbine which can fuse multi-sensors data in different resolution. The fusing result indicates the designed modified algorithm is effective.
