Abstract (en)
It is an objective to provide a rail track branch detection apparatus and a program that can detect a branching track of a railroad with higher accuracy. The rail track branch detection apparatus according to an embodiment includes a track detector and a clustering device. The track detector executes track detection of detecting a track of one route of a railroad vehicle from an image captured in an advancing direction of the railroad vehicle, multiple times according to the number of a plurality of preset detection parameters. The clustering device detects a branch of the track in the image by classifying a plurality of track detection results obtained by the track detector into a plurality of clusters.
