可以在 `print_resolution()` 函数中添加设置分辨率的代码，使得选择不同的分辨率后，可以动态调整画面分辨率。

具体实现方法如下：

1. 在 `print_resolution()` 函数中添加以下代码，用于根据选择的分辨率设置画面分辨率：

if Resolution == '0':
    # 设置画面分辨率为 640x480
    video.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
    video.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)
elif Resolution == '1':
    # 设置画面分辨率为 800x600
    video.set(cv2.CAP_PROP_FRAME_WIDTH, 800)
    video.set(cv2.CAP_PROP_FRAME_HEIGHT, 600)
elif Resolution == '2':
    # 设置画面分辨率为 1024x768
    video.set(cv2.CAP_PROP_FRAME_WIDTH, 1024)
    video.set(cv2.CAP_PROP_FRAME_HEIGHT, 768)
elif Resolution == '3':
    # 设置画面分辨率为 1280x720
    video.set(cv2.CAP_PROP_FRAME_WIDTH, 1280)
    video.set(cv2.CAP_PROP_FRAME_HEIGHT, 720)
elif Resolution == '4':
    # 设置画面分辨率为 1920x1080
    video.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
    video.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)

2. 在 `video_connect_option()` 函数中添加以下代码，用于初始化默认的分辨率：

Resolution = '0'

完整的代码如下：

# 视频连接参数面板
def video_connect_option():
    global Resolution, ShowMe, Version, AudioOpen
    
    # 初始化分辨率为 640x480
    Resolution = '0'
    
    video_connect_option = tkinter.Toplevel()
    video_connect_option.wm_geometry('150x450')
    video_connect_option.title('连接参数')
    
    # 分辨率面板
    var1 = tkinter.StringVar()
    label1 = tkinter.Label(video_connect_option, bg='#f0f0f0', width=20, text='分辨率')
    label1.pack()
    
    def print_resolution():
        global Resolution
        Resolution = var1.get()
        label1.config(text='分辨率 ' + Resolution)
        
        # 根据选择的分辨率设置画面分辨率
        if Resolution == '0':
            video.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
            video.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)
        elif Resolution == '1':
            video.set(cv2.CAP_PROP_FRAME_WIDTH, 800)
            video.set(cv2.CAP_PROP_FRAME_HEIGHT, 600)
        elif Resolution == '2':
            video.set(cv2.CAP_PROP_FRAME_WIDTH, 1024)
            video.set(cv2.CAP_PROP_FRAME_HEIGHT, 768)
        elif Resolution == '3':
            video.set(cv2.CAP_PROP_FRAME_WIDTH, 1280)
            video.set(cv2.CAP_PROP_FRAME_HEIGHT, 720)
        elif Resolution == '4':
            video.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
            video.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
    
    r0 = tkinter.Radiobutton(video_connect_option, text='0', variable=var1, value='0', command=print_resolution)
    r0.pack()
    r1 = tkinter.Radiobutton(video_connect_option, text='1', variable=var1, value='1', command=print_resolution)
    r1.pack()
    r2 = tkinter.Radiobutton(video_connect_option, text='2', variable=var1, value='2', command=print_resolution)
    r2.pack()
    r3 = tkinter.Radiobutton(video_connect_option, text='3', variable=var1, value='3', command=print_resolution)
    r3.pack()
    r4 = tkinter.Radiobutton(video_connect_option, text='4', variable=var1, value='4', command=print_resolution)
    r4.pack()

注意：上述代码中使用了 `video` 变量，需要在调用 `video_connect_option()` 之前打开视频流并将其赋值给 `video` 变量。
