| Abstract: | The real-time video monitoring was carried out for the tunnel crack. At first, the de-noising pretreatment was carried out for image signal through the transcendental Wiener filter in wavelet field. Then, the image edge features were extracted. At last, based on space relationship, the image search technology was used to monitor the relative locations of image edge. The cracks and their real-time state were estimated and calculated. The theory analysis and test results showed that this method was practical in the industry field. |
