将OpenCV的框架移至Tkinter时，Python中的Memory Error和AttributeError

如何解决将OpenCV的框架移至Tkinter时，Python中的Memory Error和AttributeError

我试图将OpenCV的框架移至Tkinter

代码跟随中...

import tkinter as tk
import time

from PIL import ImageTk,Image
from cv2 import cv2

显示视频

class CamWindow:
    def __init__(self,window,title:str,cam_plug = 0,delay = 15):

        self.delay = delay

        self.window = window

        self.title = title
        self.window.title(self.title)

        self.cam = MyVideoCapture(cam_plug)

        self.canvas = tk.Canvas(self.window,width = self.cam.width,height = self.cam.height)
        self.canvas.pack()

        self.photoButton = tk.Button(self.window,text="SnapShot",width=30,command=self.shot)
        self.photoButton.pack(anchor=tk.CENTER,expand=True)
        self.update()
        self.window.mainloop()

    def shot(self):
        ret,frame = self.cam.getPic()
        if ret:
            cv2.imwrite(time.strftime("%d-%m-%Y-%H-%M-%S")+".jpg",cv2.cvtColor(frame,cv2.COLOR_RGB2BGR))

    def update(self):
        ret,frame = self.cam.getPic()
        if ret:
            self.photo = ImageTk.PhotoImage(image=Image.fromarray(frame))
            self.canvas.create_image(0,image = self.photo,anchor = tk.NW)
        self.window.after(self.delay,self.update())

class MyVideoCapture:
    def __init__(self,cam_plug = 0):
        self.cam = cv2.VideoCapture(cam_plug,cv2.CAP_DSHOW)
        if not self.cam.isOpened():
            raise ValueError("cannot open camera at %d",cam_plug)
        self.width = self.cam.get(cv2.CAP_PROP_FRAME_WIDTH)
        self.height = self.cam.get(cv2.CAP_PROP_FRAME_HEIGHT)

    def getPic(self):
        if self.cam.isOpened():
            ret,frame = self.cam.read()
            if ret:
                return ret,cv2.COLOR_BGR2RGBA)
            else:
                return ret,None
        else:
            return None,None

    def __del__(self):
        if self.cam.isOpened:
            self.cam.release()

终端显示内存错误，但是一切似乎都有意义。

，我也遇到了“ Attributeerror：'photoimage'对象没有属性'_photoimage__photo'” 如果有任何方法或代码有问题，请也告诉我 =========================编辑====================== ====

我的主要file.py是：

from module.UI import CamWindow

def main():
    CamWindow(tk.Tk(),title = "camera window",delay = 30)


if __name__ == '__main__':
    main()
