A recently granted patent (Publication Number: US11912320B2) describes a system designed for visualizing and quantifying surface damage on a railroad track. The system includes a camera attached to a transport device that travels along the track, capturing image data of the rail's surface. This data is then processed by one or more processors to identify defects, determine metrics associated with these defects, and display the results on an electronic device. The system can generate images of the rail's surface divided into elongated portions, analyze these portions for defects like cracks or pitting, and display graphs showing the metrics for each portion.

Furthermore, the system can display visual markers indicating specific locations and corresponding metric values along the rail's surface. The processors are capable of transmitting image data, surface images, and metric graphs to external devices. The system's functionality extends to dividing the surface image into regions for detailed defect analysis, allowing for a comprehensive assessment of surface damage. The metrics provided include crack density, crack angle, crack width, pitting density, surface damage density, and surface region index, among others. Overall, this patented system offers a sophisticated solution for efficiently visualizing and quantifying surface damage on railroad tracks, aiding in maintenance and safety efforts.
