一、概念和环境搭建
什么是opencv?
搭建过程？
1）从python.org下载python，要下载3.0版本以上的；
2）下载pycharm
3）搭建opencv，依次输入如下命令
pip install opencv-python
pip install opencv-contrib-python
pip install pytesseract
若遇到如下的问题，则在cmd下输入pip install Flask命令；
Exception:

return s.decode(sys.__stdout__.encoding)

During handling of the above exception, another exception occurred:

二、pycharm的使用
三、opencv模块
