Abstract
<p> The authors have developed a Cable-stayed bridge cable inspection robot to improve the efficiency of cable inspection of Cable-stayed bridges. The six cameras are mounted in the robot and takes a video of the whole circumference of the cable surface at a single elevation. It is characterized by making an expanded view of image from the taken video. In this paper, the red LEDs on the green circuit boards are installed in the Cable-stayed bridge 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. In addition, application to the tube which imitated the cable is presented so as to demonstrate the accuracy of the automatic detection method.</p>
