【pyqt5】将imshow改在qlabel中输出

                height, width, bytesPerComponent = im0.shape
                bytesPerLine = bytesPerComponent * width
                # 变换彩色空间顺序
                cv2.cvtColor(im0, cv2.COLOR_BGR2RGB, im0)
                # 转为QImage对象
                self.image = QImage(im0.data, width, height, bytesPerLine, QImage.Format_RGB888)
                self.label.setPixmap(QPixmap.fromImage(self.image).scaled(self.label.width(), self.label.height()))
