如何使用opencv将图像显示到PYQT

如何使用opencv将图像显示到PYQT

它有2个错误：

• 您必须将传递

  bytesPerLine

  给QImage

• trainOpenImg

  设置对齐方式时，您会输入更多的“ n” 。

def displayImage(self):    qformat =QImage.Format_Indexed8    if len(self.image.shape)==3:        if self.image.shape[2] ==4: qformat=QImage.Format_RGBA8888        else: qformat=QImage.Format_RGB888        img = QtGui.QImage(self.image.data, self.image.shape[1], self.image.shape[0],  self.image.strides[0], # <--- +++ qformat)        img = img.rgbSwapped()        self.trainOpenImg.setPixmap(QPixmap.fromImage(img))        self.trainOpenImg.setAlignment(QtCore.Qt.AlignCenter)

另一方面，IDE在处理某些类型的错误时遇到问题，只能启动代码，因此，在这种情况下，建议在CMD或终端中运行它，因为它们会为您提供更多信息，例如，在这种情况下，错误消息为：
