Does the whiter it is, the higher the temperature?

Look at the whiteness. It looks like the same white as your hand. So is it the same temperature as your hand? It should feel hotter than your hand.

The correspondence should be very high, because black and white pictures can only display 0 to 255. I set it to display the same brightness when it is greater than a certain temperature.

A direct digital display of temperature

Is it achieved directly using camera + image processing?

This won't work. It will automatically adjust the brightness, so it will be related to the temperature according to the output data.

The thermal imaging output data is converted into 8-bit grayscale images for direct display

I strongly suggest that you also post the tutorial for homemade thermal imaging washing, I want to do it!
