In order to break through key core technologies such as highway networking, road property right-of-way status, and road disease identification, an innovation team jointly established by Fujian Provincial Expressway Group Luoning Company, the Institute of Science and Technology, and the Institute of Geography of the Chinese Academy of Sciences worked hard during the research and development process of this project. In order to solve the professional technical problems of improving crack extraction performance and identification accuracy, a deep learning pavement crack extraction method and device were developed, which effectively solved the problems of low efficiency and high cost of traditional pavement crack inspection, and has great practicality, and The research and development of this patent is difficult, time-consuming and has high gold content. This invention patent is characterized by "high value and high quality", so the application and approval cycle is only more than 3 months.
