摘要
小波变换可以把噪音信号从有效信号中去除,并对图像进行分解处理;通过多尺度下的基于小波变换,可以检测并表征一个图像信号。利用此信号处理方法,可有效地实时检测与识别电池钢壳口部的裂纹。
The noise signals could be eliminated from the effectual signals by the wavelet transformation, and the images were decomposed and treated. Based on the wavelet transformation under multi-dimensions, the detection and characterization of a image signal could be done. The opening crackle of the battery can could be effectively detected and identified by using this signal treated method.
