Abstract: Изобретение относится к области регулирования движения дорожного транспорта. Способ настройки видеокамеры для более качественного распознавания ГРЗ в системах фиксации нарушений ПДД состоит в том, что вместо встроенного в видеокамеру механизма автоматического выбора параметров работы в зависимости от условий съемки используется программный механизм настройки режима работы камеры. При этом указанный программный механизм предусматривает два режима настройки камеры: 1) грубой настройки, когда ГРЗ не видны в кадре или не распознаются, и 2) тонкой настройки, когда ГРЗ видны в кадре и распознаются. Механизм грубой настройки использует эмпирически найденные значения характерной яркости кадра, оптимальные для распознавания ГРЗ при различных уровнях яркости снимаемой сцены, где уровень яркости снимаемой сцены определяется по параметрам настройки камеры. Механизм тонкой настройки используется, когда в кадре есть программно найденные изображения ГРЗ, и корректирует режим работы видеокамеры для достижения оптимальных характерных яркостей фона и символов на найденных ГРЗ. Достигается повышение качества распознавания ГРЗ в системах фиксации нарушений ПДД. 1 ил.
