AI Technical Summary
Existing technologies struggle to accurately locate abnormal areas where suction cups adhere during the transport of tunnel segments, resulting in low accuracy of early warnings, low efficiency in troubleshooting, and frequent false alarms.
By collecting the overall point cloud of the transport vehicle, the contour of the feature lines of the pipe segment edge is obtained, the accurate pose of the suction cup group is determined, and the changes in adsorption angle and negative pressure are monitored in real time. Combined with the pipe segment type, abnormal areas are identified and dynamic early warnings are issued.
It improves the efficiency of segment grabbing and positioning, avoids bumps and damage, ensures uniform adhesion of the suction cup, accurately identifies surface damage, reduces false alarms, predicts the risk of segment detachment, and avoids safety accidents.
