一个显示图像的Pyside6模板

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())
