小波滤波在白车身装焊误差区域识别中的应用

The Application of Wavelet Filtering in Regional Recognition

采用小波滤波方法对白车身原始三坐标测量数据进行滤波,对滤波后得到的趋势项进行聚类分析,进而识别白车身装焊误差区域。结果表明,这种方法可更准确的识别出误差区域。

Filtering the original three coordinates measurement data of white body by wavelet filtering,and then a clustering analysis was done on the trend term, for identifying the white body fabrication error area. The results show that this method can more accurately identify error area.
