Tkinter 内存错误：打开简历视频几秒后停止

如何解决Tkinter 内存错误：打开简历视频几秒后停止

我对编码非常陌生，在尝试使用 Open CV 和 Tkinter 可视化视频时遇到了问题。 我正在构建一个 GUI，其中可以可视化 esp32cam 捕获的帧，通过网络服务器访问它们，然后可以拍摄照片。此外，还有一些按钮可以通过向 Arduino 发送字符来控制机器人的运动。

问题是，大约 40 秒后图像冻结，我得到：

Exception in Tkinter callback
MemoryError

涉及opencv和视频的部分代码是：

def visualize_video():
    def take_picture(event=""):
        Now = time.strftime("%Y%m%d-%H%M%s") 
        image_name = f"img{Now}.jpg" 
        cv2.imwrite(image_name,img)
            
    imgResponse = urllib.request.urlopen (url) 
    imgNp = np.array(bytearray(imgResponse.read()),dtype=np.uint8)
    img = cv2.imdecode (imgNp,1) 
    img = cv2.rotate(img,cv2.ROTATE_90_Clockwise) 
    img = cv2.cvtColor(img,cv2.COLOR_BGR2RGB) 
        
    vid = Image.fromarray(img) 
    video = ImageTk.PhotoImage(image=vid) 
    video_label = Label(window) 
    video_label.grid(row=1,column=0,rowspan=5,columnspan=2,padx=10)
    video_label.configure(image=video) 
    video_label.image = video
    video_label.after(10,visualize_video) 

    bpicture = tk.Button(window,text="Take picture",command=take_picture,bg='red3',fg='gray7',font=('Comic Sans MS',14))
    bpicture.grid(row=0,padx=5,pady=10,columnspan=2) 
    window.bind("<space>",take_picture) 

整个程序如下：

from tkinter import *

from PIL import ImageTk
import cv2
import numpy as np

window = tk.Tk()

window.title('Robot Explorador - PYTHON GUI')

ArduinoUNO = serial.Serial(port='COM4',baudrate=9600,bytesize=8)

def visualize_video():
    def take_picture(event=""):
        Now = time.strftime("%Y%m%d-%H%M%s") 
        image_name = f"img{Now}.jpg" 
        cv2.imwrite(image_name,take_picture)
