from PySide6.QtCore import Qt
    from numpy import ndarray
    from PySide6.QtWidgets import QApplication, QMainWindow, QLabel, QVBoxLayout, QWidget
    from PySide6.QtGui import QPixmap
    from PIL import Image, ImageQt
    
    class ImageViewer(QMainWindow):
        def __init__(self):
            super().__init__()
    
            self.initUI()
    
        def initUI(self):
            self.setWindowTitle('Image Viewer')
            self.setGeometry(100, 100, 300, 300)
    
            layout = QVBoxLayout()
    
            # 创建一个 QLabel 用于显示图像
            self.label = QLabel(self)
            # 顶部对齐
            self.label.setAlignment(Qt.AlignTop)
            layout.addWidget(self.label)
    
            widget = QWidget()
            widget.setLayout(layout)
            self.setCentralWidget(widget)
    
        def updateImage(self, image_data: Image):
            # 转一下
            q_image = ImageQt.ImageQt(image_data)
    
            # 将 QImage 转换成 QPixmap，并显示在 QLabel 中
            pixmap = QPixmap.fromImage(q_image)
            self.label.setPixmap(pixmap)

使用

if __name__ == '__main__':
       
        .....
    
        # 用Qt动态显示一下图像
        app = QApplication(sys.argv)
        viewer = ImageViewer()
        viewer.show()
    
        image_container = ImageContainer(300, 100)
    
        while True:
            try:
                image: ndarray = camera.get_image()
                if image is not None:
                    
                    container_image = image_container.get_base_container_image()
                    viewer.updateImage(container_image)
    
                key = cv2.waitKey(50) & 0xFF
                if key == ord('e') or key == ord('E'):
                    cv2.destroyAllWindows()
                    break
            except Exception as e:
                print(e)
    
        sys.exit(app.exec())
