Research on Road Damage Recognition Algorithm Based on OpenCV
A crack backbone extraction algorithm is proposed based on image processing techniques such as median filtering,histogram equalization,and non-sharpening masks to address the issue of road surface conditions affecting the effectiveness of crack backbone extraction.The comparison result with manual threshold segmentation algorithm,Otsu threshold algorithm,and maximum entropy threshold segmentation algorithm shows that this algorithm can effectively extract the crack backbone area,reduce the number of image noise,and have important guiding significance for improving the anti-interference performance of road crack extraction algorithm.
