Abstract

Описаны способ и система для идентификации номера и типа вагона и способ и система для инспекции безопасности вагонов. Способ идентификации номера вагона включает использование (S202) камеры с линейным сканированием, движущейся относительное инспектируемого вагона, для последовательного фотографирования инспектируемого вагона с получением множества отдельных изображений вагона; сшивание (S204) множества отдельных изображений вагона с формированием сшитого изображения; коррекцию (S206) искажений сшитого изображения с получением скорректированного изображения и идентификацию (S208) номера вагона по скорректированному изображению. Коррекция искажений в сшитом изображении включает извлечение контура колеса из сшитого изображения; получение на основе контура колеса отношения горизонтального диаметра колеса к вертикальному диаметру колеса; если это отношение больше первого заранее заданного порога, то выполнение сжатия сшитого изображения в горизонтальном направлении согласно указанному отношению; а если это отношение меньше заранее заданного второго порога, то растягивание сшитого изображения в горизонтальном направлении. Раскрытые способ и система обеспечивают автоматическую идентификацию модели вагона и проведение инспекции безопасности вагонов, обеспечивая, таким образом, высокую производительность, удобство и простоту использования.
