Thingsboard local usb camera demo (IoT)

This project is just a demo, it's function include:

• Emotion Recognition use local usb camera(has two steering gear) on Respberry PI 4B.
• Use vidgear transmit real-time streaming to thingsboard cloud server.
• Add a thingsboard widget to display the real-time streaming.
• Control the steering gear from cloud manual or automatic (Arduino and zigbee).(TODO)

server code

• Vidgear is a multi-threaded Video Processing Python framework. The server receive the streaming from the client.
• Cloud server has a flask http service to receive the tcp real-time streaming from Respberry PI on local area network and listening a http port 15000. You can display the vedio stream on http://ip:15000.

client code

• Client code run on PI 4B in LAN.
• Emotion Recognition ref emotion_rec.
