1. A thermal imaging system, comprising:
a thermal camera assembly operable to generate thermal images of a scenery in a real world and having an actual mounting height in the real world different from a predetermined reference mounting height; and
a computing device connected to the thermal camera assembly;
wherein the computing device is configured to guide, via a mobile application, a user of the mobile application to position a reference object, visible in the thermal images generated by the thermal camera assembly, at a location in the scenery to capture the reference object in a first thermal image generated by the thermal camera assembly; and
wherein the computing device is further configured to calibrate mapping between a coordinate system of the thermal images and a coordinate system in the real world based on the predetermined reference mounting height, and a first height of the reference object as in the first thermal image from the thermal camera assembly.
