Rail-DB Navigable Track Area DataSet

The Rail-DB_NTA (Rail-DB Navigable Track Area) is a collection of real-world train track images captured under three different lighting conditions, the images are selected from the \u201cfixed_day\u201d, \u201cfixed_night\u201d, \u201cfixed_rain\u201d, and \u201cfixed_rain_2\u201d subsets of the Rail-DB dataset present by Xinpeng Li. The images are then re-annotated by a new novel strategy that jointly labels track lines and navigable areas. Given the unique challenges of railway track--such as turnouts and intricate curvature variations--this dataset aims to support research in autonomous railway systems, track detection algorithms, and navigable area identification solutions.
