  1. Visual Monitoring of Railroad Grade Crossing and railroad tracks University of Central Florida

  2. Visual Monitoring of Railroad Grade Crossing Phase I

  3. Objectives • Monitor railroad grade crossing for hazardous behavior. • Issue a audio/visual alert. • Self-contained portable system

  4. System Overview • The main processing pipeline of the system:

  5. The Portable System Camera Solar Panels Main Processing Unit Carrying Unit Batteries Computer Vision LaboratoryUniversity of Central Florida

  6. Website Interface • Each site contains • Live image • Latest log file data • Trains detected • Train title • Date • Time • Objects detected • Object ID • Date/Time Computer Vision LaboratoryUniversity of Central Florida

  7. Email Alerts • Email alerts are triggered on activities • Alert frequency can be changed by user parameters • Each email contains • Site source location • Message about activity • Image of object involved in activity Computer Vision LaboratoryUniversity of Central Florida

  8. P421 P127 P135 Performance Evaluation • Detected Violators Mount Dora 03-01-2005, 11:32:33 03-01-2005, 11:32:19 03-08-2005, 13:18:23 New Smyrna Beach 03-11-2005, 15:17:53 03-02-2005, 12:42:57 02-22-2005, 11:01:42

  9. Visual Inspection of Railroad Tracks Phase II

  10. Basler A400 High speed firewire Mobile Platform Design

  11. Mobile Platform • The main factors driving the design of the mobile platform are: • Portability • Image Stability • Uniformity of Illumination conditions

  12. Mobile platform

  13. Video obtained from mobile platform Example rail video obtained from mobile platform

  14. Defect detection

  15. Engine Burn Defects • A condition in which the rail has been scarred by the heat created by locomotive. • Appearance in track. Round or oval rough spots or holes on the surface of the rail. 1 Burn area Burn area 1 Railroad Track Standards, Departments of the Army (TM 5-628)

  16. Processing Pipeline SVM

  17. Results = Detection = Confidence

  18. Results

  19. Results Potential burn regions

  20. Rail Crack Defects

  21. Rail Cracks • Stress caused by the wheels of the train can lead to cracks on the rail head. Rail Stress

  22. Processing Pipeline

  23. Current work

  24. Rail Gauge Verification • Objective: • Verify that the distance between rails is within a safe margin. Rail Gauge Synchronized high speed cameras

  25. Missing Fasteners • Detect missing fasteners Steel Clips or Fasteners Missing fasteners

  26. Thank you
