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.
