摘要
针对墙体表面不等宽度的裂缝,提出一种自适应裂缝宽度的二值化方法。通过与分块迭代二值结果进行求交去噪和形态学处理,得到裂缝信息较完整且可信度更高的二值图像。该方法可剔除块状缺陷和大块背景污渍的影响,针对不等宽度的线状缺陷进行效果较好的二值化操作。
In order to determine the linear features of cracks with different characteristics and widths,an adaptive searching binary method is proposed.Through intersection operation with block iterative binary results and a morphological process,a more complete and reliable binary result can be obtained.It is demonstrated experimentally that the method can eliminate the influence of bulk defects and get good effect on the linear features of different width cracks.
