Abstract
In order to solve the problems of low efficiency,high safety risks,and high labor intensity in using traditional methods to detect bridge apparent defects,a new type of intelligent bridge detection robot system has been independently developed,and the overall architecture and on-site workflow of the intelligent bridge detection robot are introduced.Furthermore,a feature-based image stitching method and an improved YOLO_v3 intelligent identification algorithm for bridge apparent defects based on transfer learning are proposed.The engineering application results show that the developed bridge intelligent detection robot system integrates mechanical control modules,data acquisition modules,and data processing modules.Through the robot system,the automation,intelligence,and informatization of bridge detection have been achieved.Based on transfer learning and data enhancement,an intelligent crack identification algorithm for modified YOLO_v3 bridge is proposed,which has good detection accuracy and noise resistance without losing detection efficiency.The new type of intelligent bridge detection robot system provides hardware and software support for intelligent detection of bridge engineering.
