Тестирование производительности показало, что среднее время распознавания
данных паспорта составляет 832 мс, а среднее время распознавания данных
страхового свидетельства - 581 мс, что удовлетворяет требованию к максимальному
времени распознавания в 1 с.
Среднее время внесения данных при помощи оптического распознавания
составило для паспорта 39,8 с, для страхового свидетельства - 23,4 с. Замер
времени производился между запуском операции распознавания (RecognitionActivity) и нажатием на кнопку сохранения
документа в БД.
Для оценки скорости внесения данных документов вручную была использована
операция DocumentActivity с пустыми текстовыми полями. Время
замерялось между началом ввода и нажатием кнопки «Сохранить» и в среднем
составило: для паспорта - 1 мин 23,9 с, для страхового свидетельства - 1 мин 1
с.
Таким образом, для паспорта время автоматического ввода оказалось меньше,
чем ручного, в 
раза, а для страхового свидетельства - в 
раза.
ЗАКЛЮЧЕНИЕ
В ходе выполнение выпускной квалификационной работы был проведен анализ
существующих решений по распознаванию данных документов, удостоверяющих
личность, изучены теоретические основы в области компьютерного зрения и
алгоритмы обработки изображений и оптического распознавания символов.
Была спроектирована база данных для использования в приложении.
Разработаны алгоритмы обнаружения и распознавания текста в документе,
использующие преимущественно возможности библиотеки OpenCV. Спроектирован пользовательский интерфейс приложения
на ОС Android.
Было разработано приложение в интегрированной среде разработки Android Studio. К приложению подключена локальная БД SQLite для сохранения данных распознанных
документов. Реализован простой механизм аутентификации пользователя в системе.
Также была обучена библиотека Tesseract для шрифтов, используемых в паспортах РФ и страховых свидетельствах.
В результате тестирования приложения ошибок в его работе не обнаружено.
Точность распознавания зависит от условий освещенности и камеры устройства и в
среднем составляет не менее 90%. Также стоит отметить, что интересующий текст
на документах может быть плохо пропечатан или, например, сливаться с другими
объектами, что тоже оказывает отрицательное влияние на точность распознавания.
Время, затрачиваемое на распознавание, удовлетворяет техническому заданию.
Использование технологий оптического распознавания дало прирост к скорости
внесения данных документов более чем в 2 раза по сравнению с ручным вводом.
Приложение может использоваться на смартфонах с ОС Android 4.0 и выше, имеющих камеру с
разрешением не менее 2 Мп с автофокусом, и не требует доступ к интернету.
