ht-301 thermal camera opencv python lib.
It's a very simple hacked together lib, might be useful for somebody,
uses matplotlib which is a little bit on the slow side,
or pure opencv - much faster but without most features
Tested on ubuntu 20.04:
$ ./pyplot.py
keys:
'h' - help
' ' - pause, resume
'u' - calibrate
't' - draw min, max, center temperature
'a', 'z' - auto exposure on/off, auto exposure type
'w' - save to file date.png
',', '.' - change color map
left, right, up, down - set exposure limits
$ ./opencv.py
