| 摘 要： | 为了更好地检测路面不平度的突变,提出了基于小波变换提取路面不平度突变的方法。利用小波变换检测路面不平度突变的基本原理和路面不平度不同尺度的最大重叠离散小波变换系数进行路面不平度突变区域的检测。结果表明:在消除边缘效应后,在两个突变区域内,W1、W2和W3小波系数具有一致性,可以准确提取路面不平度突变。

| Abstract: | In order to improve the detection of road roughness with abrupt changes,a method of extracting the road roughness with abrupt changes based on wavelet transform is proposed.Employing the fundamental principle of the detection of road roughness with abrupt changes based on Wavelet Transform,the maximal overlap discrete wavelet transform coefficients in different scales are adopted to detect the abrupt areas of the road roughness.The experimental results have showed that after eliminating the edge effect,the ... |
