KivyMD App Error : build self.image = Image() TypeError: 'module' object is not callable

Question

我正在尝试使用 pytesseract、opencv 和 KivyMD 作为本教程构建文本扫描仪应用程序：https://www.youtube.com/watch?v=xIYbgCvFfdQ&list=PL0lYY7rL__yLMEI7k9hA8L1EOVlH79FyY&index=2

但我的结果是空窗口和错误。请帮忙

这是我的代码 main.py

from kivymd.app import MDApp
from kivymd.uix.boxlayout import MDBoxLayout
from kivymd.uix.button import MDRaisedButton
from kivy.uix.image import Image
from kivy.graphics.texture import Texture
from kivy.clock import Clock
import cv2
import pytesseract
from kivymd.uix.label import MDLabel
from PIL import Image

class MainApp(MDApp):

    def build(self):
        layout = MDBoxLayout(orientation='vertical')
        self.image = Image()
        self.label = MDLabel()
        layout.add_widget(self.image)
        layout.add_widget(self.label)
        self.save_img_button = MDRaisedButton(
            text="CLICK HERE",
            pos_hint={'center_x': .5, 'center_y': .5},
            size_hint=(None, None))
        self.save_img_button.bind(on_press=self.take_picture)
        layout.add_widget(self.save_img_button)
        self.capture = cv2.VideoCapture(1)
        Clock.schedule_interval(self.load_video, 1.0/30.0)
        return layout

    def load_video(self, *args):
        ret, frame = self.capture.read()
        # Frame initialize
        self.image_frame = frame
        buffer = cv2.flip(frame, 0).tostring()
        texture = Texture.create(size=(frame.shape[1], frame.shape[0]), colorfmt='bgr')
        texture.blit_buffer(buffer, colorfmt='bgr', bufferfmt='ubyte')
        self.image.texture = texture

    def take_picture(self, *args):
        image_name = "picture_at_2_02.png"
        img = cv2.cvtColor(self.image_frame, cv2.COLOR_BGR2GRAY)
        img = cv2.GaussianBlur(img, (3, 3), 0)
        img = cv2.threshold(img, 0, 255, cv2.THRESH_BINARY_INV+cv2.THRESH_OTSU)[1]
        text_data = pytesseract.image_to_string(img, lang='eng', config="--oem 3 --psm 6")
        print(text_data)
        self.label.text = text_data
        cv2.imshow("cv2 final image", img)
        cv2.imwrite(image_name, self.image_frame)



if __name__=="__main__":
    MainApp().run()

以下是错误：

 Traceback (most recent call last):
   File "c:/Users/aroon/prac python/MyApp/main.py", line 53, in <module>
     MainApp().run()
   File "C:\Users\aroon\Anaconda3\lib\site-packages\kivy\app.py", line 949, in run
     self._run_prepare()
   File "C:\Users\aroon\Anaconda3\lib\site-packages\kivy\app.py", line 919, in _run_prepare
     root = self.build()
   File "c:/Users/aroon/prac python/MyApp/main.py", line 16, in build
     self.image = Image()
 TypeError: 'module' object is not callable

Answer 1

这是因为PIL和kivy库中的图像类被称为相同的事实-Image，您只需将类名更改为from PIL import Image as PILImage
