I am implementing ai thermometer with your kind explanation. #4

I am implementing ai thermometer with your kind explanation.

Now I am building the environment of Raspberry pi camera v2 & lepton2.5 & PureThermal2.

But nothing has happened since Uvc_open error -3 appeared after python3 main.py.

Can I know the solution?

Of course, the individual operation of each sensor was confirmed.

thank you.

Hi,

Did you change the permissions for the USB camera? (There's a short explanation in readme.md). Look under "possible issues" section.

Thank you so much.

It was executed with sudo without any problems.

Additionally, the temperature value of the ir sensor cannot be output, which part should I check?

Thank you always for your answer.

Hey,

So if you wish to read the temperature value, you will need to add something like this to the main loop:

print(ir_thread.frame.mean())

This will print the mean temperature of the 120x160 pixel array.

If you want to access the temperature of individual pixels, you'd do:

print(ir_thread.frame[0][0])

This way you'll access the value of the (0,0) pixel in degrees Celsius.

Hope this helps!
