Abstract:
The trajectory discrimination device according to an embodiment is provided with an image acquiring unit, a feature amount selecting unit, a feature data deriving unit, and a railroad track detecting unit. The image acquiring unit acquires a captured image obtained by capturing an image of an area in the traveling direction of a railroad vehicle. For every plurality of pixel groups in the captured image, the feature amount selecting unit selects, on the basis of a prescribed criterion, one feature amount used to detect a railroad track among a plurality of feature amounts that can be a measure of the likelihood of being a railroad track. The feature data deriving unit derives, from each of the plurality of pixel groups, feature data based on the one feature amount selected by the feature amount selecting unit. The railroad track detecting unit detects a railroad track in the captured image on the basis of the result of derivation of the feature data deriving unit.
