I'm working on a project where I use a Pi + camera + sensors. I would like to use the picamera module and overlay a moving plot of the real-time sensor readings on the video output by using the picamera.add_overlay(sensor readings)....
Im thinking of using matplotlib to generate a cumulative readings.jpg file every second and then use that as the overlay. Would this method work ?
Stretch goal would be to output to a network stream but am not sure if picamera supports this level of overlay. Ive seen somewhere that it works only for preview - so am a bit confused.
