Глобальные переменные в PyQT5

Question

У меня есть два основных скрипта для моего pyQT5 gui. Сначала файл GUI ("MSCVgui_script"), а затем файл запуска ("guiRun" .py). Когда я запускаю свой файл запуска, GUI вылетает, когда я изменяю переменную «self.imageFiles1» в функции assingPics.

Что я делаю:

1. запустите "guiRun.py"
2. Выберите "Обзор файла"
3. выберите папку из всплывающего окна
4. Закрыть всплывающее окно
5. установите флажок синего цвета на GUI
6. Cra sh -> нет сообщения об ошибке Пути к файлам фотографий: "C: \ Users ..... \ Images \ photo_Blue.jpg "имена" photo_Blue "

запустить Gui скрипт ниже

Я знаю, что это как-то связано с переменной класса self.imageFiles1 [i] и моим отсутствием понимания pyQT5. Может кто-нибудь объяснить, как обрабатывать глобальные переменные в скрипте запуска pyQT5?

Answer 1

imag = cv2.imread(imag, 0) возвращает изображение в оттенках серого, поэтому imag.data будет символом, содержащим height*width 8-битные целые числа вместо height*width*3, что необходимо для QtGui.QImage(imag.data, imag.shape[1], imag.shape[0], QtGui.QImage.Format_RGB888). Для загрузки цветного изображения используйте imag = cv2.imread(imag, 1) (или просто imag = cv2.imread(imag), поскольку flag == 1 является значением по умолчанию).

В качестве альтернативы вы можете просто использовать имя файла для инициализации объекта QImage вместо того, чтобы сначала создавать изображение OpenCV.

imag = QtGui.QImage(self.imageFiles1['photo_Blue'])
