提出了一种基于PDE和小波分析的破损路面检测技术。通过CCD采集路面信息,并运用PDE进行去噪处理,从而很好地保留原始图像的边缘和纹理;利用小波分析进行边缘检测,再采用Canny算法对图像边缘进行提取,以确定破损路面的位置。实验结果表明,检测结果与实际结果相吻合。

This paper puts forward a kind of testing technology of the damaged road based on PDE and wavelet analysis.Firstly,the road information is acquired through the CCD,the noise of collected pictures are removed by PDE method,and the edges and texture of the original images are kept very well.Secondly,the image edge is detected by the analysis of wavelet,and extraction of image edge is performed with Canny algorithm so as to determine the position of the damaged road.The experiment results show that the actual results and test results are identical with each other.
