2. 窗体实现

3. 运行结果

三、在线协助

一、所需工具软件

1. Pycharm, Python

2. Qt, OpenCV

二、使用步骤

1.引入库

代码如下（示例）：

# coding:utf-8
import sys
#从转换的.py文件内调用类
import cv2
from PyQt5 import QtWidgets
from PyQt5 import QtWidgets, QtCore, QtGui
from PyQt5.QtGui import *

from PyQt5.QtCore import *
from PyQt5.uic import loadUi

2.窗体实现

代码如下（示例）：


    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(617, 431)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)
        self.gridLayout.setObjectName("gridLayout")
        self.frame = QtWidgets.QFrame(self.centralwidget)
        sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Preferred, QtWidgets.QSizePolicy.Preferred)
        sizePolicy.setHorizontalStretch(5)
        sizePolicy.setVerticalStretch(5)
        sizePolicy.setHeightForWidth(self.frame.sizePolicy().hasHeightForWidth())
        self.frame.setSizePolicy(sizePolicy)
        self.frame.setFrameShape(QtWidgets.QFrame.Box)
        self.frame.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame.setObjectName("frame")
        self.gridLayout_3 = QtWidgets.QGridLayout(self.frame)
        self.gridLayout_3.setObjectName("gridLayout_3")
