| 摘 要： | 在基于机器视觉的路面病害检测中,如何进行背景均匀化以及对二值图像中存在的断点问题处理是其中的技术难点.针对该问题,提出一种自适应的倍乘因子不均匀背景去除法来对不一致路面背景进行修正,该方法具有自适应性,可以通过调节自适应因子σ修正背景;然后使用一种基于区域搜寻的断点连接算法对非连续裂缝像素进行连接,它主要基于深度优先原则进行裂缝邻域搜索,然后根据联通性原理去除断点.仿真结果表明,这两种方法对目前的路面检测技术是很好的补充.

| Abstract: | Among the pavement distress detection based on machine vision,how to remove the influence of the non-uniform background is a difficult problem,and some break-points in the binary images of pre-processing will also influence the precision of crack detection.Aimed at this problem,an adaptive multiplicative factor removal method of non-uniform background was presented for revisal of the background of un-even pavement.A break-point connection algorithm was proposed based on region searching to connect the discontinuous crack pixels.Simulation result showed that these two methods were good supplement to pavement detection technology. |
