Title Research on highway crack detection algorithm
Abstract
With the development of China's economy, the construction of the highway is increasing rapidly. As a critical national infrastructure, people need a higher quality of pavement surface and maintenance. The traditional manual methods of crack detection have shortcomings such as labor-consuming , time-consuming, inefficient, non-precision, dangerous and costly. Accurately, high speed, intelligent automatic pavement detection technologies are required.
The automatic road crack recognition method based on digital image processing was studied in this paper.The research background, domestic and foreign developments were introduced firstly in this article. Then overall design of the detection system was studied . And thirdly the digital image processing for crack detection was studied deeply,which includes the following processes: image filtering, image segmentation and edge smoothing. The final results were obtained by analyzing and calculating the identification of crack from the original image.
