AI Technical Summary
In existing technologies, the detection of the tightness of railway fasteners relies on manual inspection, which is inefficient, costly, and has a high rate of missed detection. Furthermore, image-based machine vision methods cannot identify tightness, and 3D scanning sensor equipment is expensive and requires a large amount of computing resources.
A method for detecting the tightness of railway fasteners based on depth estimation is adopted. By acquiring two-dimensional and depth images of the track structure, and combining the ZoeDepth model and the YOLOv8 model, an absolute depth distribution and track two-dimensional image annotation model are constructed to achieve automated detection of fastener tightness.
It enables low-cost, fast, and accurate detection of railway fastener tightness, reduces hardware costs and computing resource requirements, and is suitable for automated inspection of track inspection trolleys.
