| titleOfInvention | Cement notch road surface image noise reduction enhancement and crack feature extraction method |
| abstract | The invention discloses a cement notch road surface image noise reduction enhancement and crack characteristic extraction method aiming at the problems that in the cement notch road surface crack identification process, the contrast of a road surface is too low due to external factors, road surface spots are caused by road surface materials and notch self-interference is caused, and the method comprises the following steps: the image contrast is enhanced by adopting an improved local adaptive contrast enhancement algorithm after the original cement pavement image is subjected to graying processing; removing speckle noise caused by pavement materials from the image with the enhanced contrast by adopting a translation invariant Shearlet transform denoising algorithm for improving the P-M model; removing pavement grooves influencing crack characteristic extraction by applying a cement groove pavement image smoothing model established based on a unidirectional total variation UTV model to the denoised image; and (3) combining a connected domain marking method, a projection method and a rectangular frame method, providing a crack type judgment method and a crack characteristic calculation method, and realizing digital description of crack characteristics. The method has the advantages of comprehensive system, small calculated amount and easy application. |
