13 Pose game

Requirements

1. Run the code in console using command line.
2. It'll open a Python window to play the pose game.

What can we practice in this project?

• Pygame
• Pygame Zero lib
• OpenCV
• MediaPipe
• numpy
• Python while/for loop, if condition, list, etc.

体感游戏

项目需求

• 直接在控制台使用命令行运行
• 运行之后出现体感小游戏

项目练习

• Pygame
• Pygame Zero lib
• OpenCV
• MediaPipe
• numpy
• Python while/for loop, if condition, list, etc.

项目参考代码

• game.py 主程序
• pose_util.py 人体姿势识别模块
• utils.py 工具模块
• video.py 测试安装代码

测试运行

将代码保存为game.py，然后在控制台运行：

python game.py
