• Abstract:
  Researchers at HiDef/Createc have completed prototype development and testing of a novel track video surveying technology ; called Track and Track-Side Video Survey (TTVS). TTVS is designed to capture clear video images of the track and track side ; areas from a moving platform at speed. This video data can be used to augment manual visual surveys and to add contextual value ; to existing data sets. The system has a user-friendly interface that allows for efficient data display and manipulation. Researchers ; completed trials of the prototype TTVS system on railroads in Maryland and Florida and demonstrated the system’s ability to ; gather detailed imagery of the track and track-side at a resolution of 1 mm. Clear images were obtained at speeds up to 28 mph ; under a variety of weather conditions. Researchers also demonstrated the linking of external data to the video using geo-referencing techniques and used a novel algorithm to geo-track images within the field of view. With additional development, the ; TTVS system can be employed in various track inspection and documentation tasks. Recommendations for future development ; include improving video resolution at higher speeds, dynamic linking of external data, and creating algorithms to make ; measurements directly from the video images.
