环境安装

安装python需要的依赖包

cv2 安装可以参考这里：https://javapub.blog.csdn.net/article/details/123656345

安装webdriver -> chrome

下载对应版本，放在本地 D:\anaconda3\Scripts 目录下

https://registry.npmmirror.com/binary.html?path=chromedriver

效果展示

GIF效果：https://tva2.sinaimg.cn/large/007F3CC8ly1h0ku3yh9g5g31ex0pfwus.gif

cv2使用参考：https://blog.csdn.net/RNG_uzi_/article/details/90034485
