在python PyQt5中添加Qframe和Matplotlib

问题描述

我正在尝试使用Python PyQt5运行一个程序，在该程序中我将2个摄像头的ip传输到我的屏幕上，但是像这样的流（请检查第一个图片）就像给定图片中的一个一样出现蒸汽会在上半年出现，但我真正想要的是将代码的顶部布局分成两半（请查看第二张图片以更好地理解），该代码位于水平布局中，不在一起只是屏幕的第一半（我也得到了这些黑色边框，如果有人知道如何将其删除，请告诉我）。
在视频流位于底部布局的顶部布局中之后，我试图获取一个Graph和一个空窗口小部件，可以对其进行编辑以供以后使用。

预先感谢

import matplotlib.pyplot as plt

def UI():

    # Set x-axis range
    plt.xlim((-4,4))

    # Set y-axis range
    plt.ylim((0,8))

    #setting background color
    ax = plt.axes()
    ax.set_facecolor('black')

    # Draw lines to split quadrants
    plt.plot([0,0],[0,8],linewidth=3,color='blue' )
    plt.plot([-4,4],[4,color='blue' )
    plt.title('Quadrant plot')

    plt.show()

UI()

解决方法

嘿，所以我能够使用已有的代码来解决问题，因此我将仅在pyqt上流式传输视频，并使用子进程调用我使用MATLAB制作的.exe文件，因此在这里您确实拥有外观。（这里我现在还没有叫Subprocess）
