per pixel tempreature data #74

Closed Bridge313 closed 2 years ago

Bridge313 commented 2 years ago

How do I retrieve per pixel temperature readings from the captured Lepton image?

jveitchmichaelis commented 2 years ago

Are you using a PureThermal? If so then the pixel values should already be in temperature units, just scaled.

Bridge313 commented 2 years ago

I am using flir letpon 3.5 and a PureThermal Mini

What is the scaling that would need to be applied to image to get the celcius temperature values.

from flirpy.camera.lepton import Lepton

camera = Lepton()
image = camera.grab()

Should be a factor of 100 and that gives you the value in Kelvin, so subtract 273 to get C.

Hi @Bridge313 - please close the issue if you got this working, thanks!
