pycharm 上安装opencv-python模块，opencv-contrib-python模块，python-pytesseract 模块

编写程序：

import cv2 as cv
src=cv.imread("C:/Users/a/Desktop/csdn/1.jpg")         #read a picture
cv.namedWindow("input image",cv.WINDOW_AUTOSIZE)       #create a GUI,named input image
cv.imshow("input image",src)                           #put picture into GUI,parameter:(GUI NAME,PICTURE)
cv.waitKey(0)                                          #wait next operation
cv.destroyAllWindows()                                 #free memory
print("hello")

测试结果：
