Calculate the internal environment for a heat chamber?

I am using a Thermal camera for a project and I am a little puzzled by how to think about calculating the internal properties. An ordinary camera will detect different points on a chessboard or something similar, but a thermal camera cannot actually distinguish these points. Can anyone understand what the built-in thermal cameras really look like?

Hooray!

EDIT. In addition to the great offers that I currently have, I also consider using aluminum foil on white to create a thermal difference. Let me know what you think of this idea.

This may or may not work, depending on the required accuracy:

  • Use a checkerboard pattern and shine on it with strong light. Black squares are likely to become hotter than white squares, so you can see the pattern in a thermal image.
  • Place small bulbs on the edges of the checkerboard pattern, light them, wait until they become hot, use a warm camera on it.

This problem is solved in a masked approach for geometric calibration of thermal infrared cameras , which mainly advocates placing an opaque mask with a chessboard squares cut from it in front of a radiation source such as a computer monitor.
