摘要
The authors have developed a cable-stayed bridge (CSB) cable inspection robot to improve the efficiency of cable inspection of CSB. Six cameras were mounted on the robot, which takes a video of the whole circumference of the cable surface as itmoves up and down the cable. The method is characterized by making an image development diagram from the taken video. In this paper, the red LEDs on the green base plate are installed in the CSB cable inspection robot in order to synchronize the cameras. Then, a time synchronization method using image processing is proposed to automatically detect the red LEDs from the taken video. Finally, this paper discusses the results of automatically detecting the detection accuracy of red LEDs lighting from the actual videos of the inclined cables, which demonstrate the robot's ability to improve work efficiency and reduce workplace hazards.
