Turn-On System

Raspberry Pi (Server)

1. Search Raspberry Pi's HOST/IP (Touch on Wi-Fi Icon, or Raspberry Pi's Terminal is key-in ip a).
   
2. Open Raspberry Pi's Terminal.
   
3. Raspberry Pi's Terminal key-in cd Desktop, goto Desktop.
   
4. Raspberry Pi's Terminal key-in python3 raspberry_pi_control.py, running program(raspberry_pi_control.py).
   
   • Python version is very important, key-in python3 -v or python -v to check your Python version default set.
     

Desktop (Client)

1. Open PC's Terminator or Terminal.
2. PC's Terminator key in cd openpose_combined, goto openpose_combined directory.
   
3. Open "main.c", and write HOST/IP (Raspberry Pi HOST/IP).
   
4. PC's Terminator key-in gcc main.c json.c -lm, will be building program main.c.
   
5. PC's Terminator key-in cd ..,it back to upper layer directory, until key-in ll can look for openpose directory.
   
6. PC's Terminator key-in cd openpose, goto openpose directory.
   
7. PC's Terminator key-in ./test "./build/examples/openpose/openpose.bin --write_json /home/Yu.Cheng/openpose_combined/json >/dev/null 2>/dev/null" "/home/Yu.Cheng/openpose_combined/a.out" 2>/dev/null, running system all (openpose and openpose_combined).
   
   • Notice: The paths and instructions in the program need to be changed according to the computer environment.
     

Turn-Off System

1. Ubuntu PC's Camera form click esc, will be stop program openpose Camera-Frame.
   
2. Ubuntu PC's Terminator click Ctrl+c, will be close program openpose and openpose_combined.
   
3. Raspberry Pi's Terminal click Ctrl+c will be break Tcp/IP and close program raspberry_pi_control.py.
