Abstract
The daily detection of shadow asphalt pavement cracks, there are multiple sets of zero points in the asphalt pavement image, which causes the detection process to take too long. Therefore, a method of shadow asphalt pavement crack detection based on cuckoo search is studied. According to the three-dimensional laser data acquisition system, the asphalt pavement crack characteristics are extracted. The zero pixel of the adjacent image area is processed by median filter. The cuckoo search algorithm is used to complete the crack search, and the crack skeleton is extracted to complete the crack detection of the shadow asphalt pavement. A section of asphalt pavement data collected by wireless laser in a certain area is used as experimental data. Three different asphalt crack samples are prepared. Two traditional crack detection methods and the crack detection methods studied in the article are used to conduct experiments. The results show that the proposed crack detection The method requires the shortest detection time.
