CameraWebServerThermal
Yet another version of the classic ESP32-CAM example CameraWebServer, this time with support for the AMG88xx thermal camera module.
Kinda works
- I'm fairly sure it leaks memory, it crashes after about half a minute when streaming the thermal camera.
- It serves an 8 by 8 image when you go to http://ESP32ipaddress/therm_capture
- It streams 8 by 8 mjpg when you go to http://ESP32ipaddress:82/therm_stream
- The regular CameraWebServer URLs are unchanged
To Do
- Fix crash
- Memory leak?
- Make image/stream larger
- Stretch pixels?
- Mix in interpolation code?
- Feed out thermocouple and temperature array via websockets and/or JSON
- Make the color map more adjustable
- Raise and lower the high and low ends of the color map
- Replace the color map with custom colors
- Delay between stream frames
- bring the frame rate down to 10 fps
The process so far
- Started with CameraWebServer
- Copied then modified the capture_handler and stream_handler with inspiration from the Adafruit_AMG88xx thermal_cam example
Hardware
- ESP32-CAM
- AMG8833 breakout module
- USB to serial for programming
