Visual Inspection of Railroad Tracks Phase II
Basler A400 High speed firewire Mobile Platform Design
Mobile Platform • The main factors driving the design of the mobile platform are: • Portability • Image Stability • Uniformity of Illumination conditions
Video obtained from mobile platform Example rail video obtained from mobile platform
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)
Results = Detection = Confidence
Results Potential burn regions
Rail Cracks • Stress caused by the wheels of the train can lead to cracks on the rail head. Rail Stress
Rail Gauge Verification • Objective: • Verify that the distance between rails is within a safe margin. Rail Gauge Synchronized high speed cameras
Missing Fasteners • Detect missing fasteners Steel Clips or Fasteners Missing fasteners
