Question

我想在tkinter的1帧中显示2个视频源，但是当我运行代码时，它仅指示网络摄像头处于打开状态，并且该帧不会出现。我是python编程的新手，所以请您帮忙

这是我的简单代码：

import cv2
import tkinter as tk
from PIL import Image,ImageTk

root = tk.Tk()
root.wm_title("Programmer is Life <3")
root.config(background="blue")

imageFrame = tk.Frame(root, width=600, height=500)
imageFrame.grid(row=0, column=0, padx=10, pady=2)

lmain = tk.Label(imageFrame)
lmain.grid(row=0, column=0)

sliderFrame = tk.Frame(root, width=252, height=225)
sliderFrame.grid(row=0, column=1, padx=10, pady=2)

lmain1 = tk.Label(sliderFrame)
lmain1.grid(row=0, column=0)

cap = cv2.VideoCapture(0)


def show_frame():
    _, frame = cap.read()
    frame = cv2.flip(frame, 1)
    cv2image = cv2.rectangle(frame, (590, 10), (350, 225), (0, 255, 255), 2)

    cv2image = cv2.cvtColor(cv2image, cv2.COLOR_BGR2RGBA)
    img = Image.fromarray(cv2image)
    imgtk = ImageTk.PhotoImage(image=img)
    lmain.imgtk = imgtk
    lmain.configure(image=imgtk)
    lmain.after(10, show_frame)

    cv2image1 = cv2.cvtColor(cv2image, cv2.COLOR_BGR2GRAY)

    blur = cv2.GaussianBlur(cv2image1, (11, 11), 0)
    blur = cv2.medianBlur(blur, 15)
    thresh = cv2.threshold(blur, 210, 255, cv2.THRESH_BINARY         
    +cv2.THRESH_OTSU)[1]
    thresh = cv2.bitwise_not(thresh)

    img1 = Image.fromarray(thresh)
    imgtk1 = ImageTk.PhotoImage(image=img1)
    lmain1.imgtk = imgtk1
    lmain1.configure(image=imgtk1)
    lmain.after(10, show_frame)

show_frame()
root.mainloop()

如何在tkinter的1帧中显示2个视频源？
