ABSTRACT:
A clearance measurement system including a video clearance measurement vehicle. The vehicle includes a video camera and a light source which emits a beam of light in a vertically and laterally extending plane. The vehicle can be driven on a railroad track at night to record illuminated portions of obstacles located along the railroad track. Various notes are overlaid on a videotape of the recorded images. The videotapes are used to prepare clearance diagrams or are analyzed by software to determine whether a reference object will pass freely along the track without hitting any of the obstacles.
