摘要
在墙体表面裂缝数字图像的基础上,通过取准中心线和插值的方法,提取图像裂纹的中心线,由中心线确定裂纹的处理区域,从而大量减少了图像处理的数据量。在裂缝图像处理区域中对图像进行OTSU阈值分割,提取出裂缝,对裂缝二值图像进行左右边界提取,进而得到裂缝宽度信息。
The surface cracks in the wall based on the digital image by taking the center line and quasi-interpolation method, extract the image of the center line crack, crack from the center line of the processing to determine the region in order to significantly reduce the image processing of data volume. Finally, cracks in image processing area OTSU image threshold segmentation, to extract the cracks, the cracks around binary image for edge extraction, and information to be crack width.
