斗地主AI出牌助手--在线调用斗地主AI，实现自动斗地主

简介

程序基于Python3.7开发的斗地主AI出牌助手，目前支持欢乐斗地主桌面版，微信版，也可以自己制作相应其他版本。
此出牌助手核心是识别出三位玩家出牌内容，调用基于DouZero封装的API接口，输入出牌内容，根据AI出牌方案，打出相应的牌。

核心功能

手牌和位置识别
1. 游戏刚开始根据屏幕位置，截图识别AI玩家手牌及三张底牌
2. 根据玩家手牌判断是否抢地主和加倍
3. 确认三者之间的关系，识别地主和农民角色，确认队友及对手关系
识别每轮三位玩家出牌
1. 根据提示按钮，判断当前的操作
2. 识别三位玩家此轮出的牌，并记录下来
AI出牌方案输出
1. 将出牌记录按格式要求发送给斗地主AI
2. 获取斗地主AI出牌方案，选取最高胜率方案
3. 根据AI出牌方案，选择对相应的牌，并出牌

素材准备

区域定位，获取坐标值
按钮及牌面
