Title:
TRAJECTORY DISCRIMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/203354
Kind Code:
A1
Abstract:
A trajectory discrimination device according to an embodiment is provided with an image acquisition unit, a rail track detection unit, a branch rail track detection unit, and a rail track detection result output unit. The image acquisition unit acquires a photographic image obtained by photographing a region in the direction of travel of a railway vehicle. For each of a plurality of pixel groups in the photographic image, the rail track detection unit detects a rail track on the basis of a feature amount serving as a criterion representing the likelihood of being a railroad track, said likelihood based on a prescribed standard. The branch rail track detection unit detects whether a branch rail track exists relative to the detected rail track. The rail track detection result output unit outputs a detection result from the rail track detection unit and a detection result from the branch rail track detection unit.
