为了解决经典的基于影像分块的统一破损指数评定方法(UCI方法)评定结果不合理的问题,提出了一种新的基于加权策略的路面影像破损评定方法。该方法首先对影像分割后的二值影像进行分块;然后统计各子块中潜在破损像素在子块中的比重,并将其作为该子块的破损程度值;最后通过对子块化后的矩阵加权统计得到影像的破损指数。试验结果对比表明:该方法比UCI方法能更准确地反映出路面破损的程度。
In order to solve the problem of the unreasonable evaluation results of the traditional method based on image segmentation, the UCI method proposed a new image damage assessment method based on weighted strategy. In this method, the binary image after image segmentation is first segmented, and then the proportion of the potential damaged pixels in each sub-block is calculated and used as the damage value of the sub-block. Finally, Matrix weighted statistics obtained by the image damage index. The comparison of test results shows that this method can reflect the degree of pavement damage more accurately than the UCI method.
