尝试使用opencv和tkinter通过按钮关闭相机

import cv2
import tkinter as tk

window = tk.Tk()
window.title("关闭相机")

def close_camera():
    cap.release()  # 释放相机资源
    window.destroy()  # 关闭窗口

button = tk.Button(window, text="关闭相机", command=close_camera)
button.pack()

cap = cv2.VideoCapture(0)  # 打开默认相机

while True:
    ret, frame = cap.read()  # 读取相机图像
    cv2.imshow("Camera", frame)  # 显示图像

    if cv2.waitKey(1) & 0xFF == ord('q'):  # 按下 'q' 键退出循环
        break

cap.release()  # 释放相机资源
cv2.destroyAllWindows()  # 关闭窗口

window.mainloop()
