Pycharm中可以直接安装第三方库，不需要使用pip install

1、进入Pycharm之后，选择“File”——“Settings”，如下图所示：

2、选择“Project Interpreter”右上方的符号“+” 。

3、在搜索框中输入opencv，选择py-opencv，如下显示"installing"，等待安装。

4、成功安装过后，我们来验证一下，输入以下代码段：

import numpy as np
    import cv2 as cv
    original = cv.imread('gongjiaoka.jpg')
    grayImg = cv.imread('gongjiaoka.jpg', cv.IMREAD_GRAYSCALE)
    cv.imwrite('mygray.jpg', grayImg)
    cv.imshow('mygray.jpg',grayImg)
    cv.imshow('gongjiaoka.jpg',original)
    cv.waitKey(0)

5、效果展示：
