How to generate a Thermal Orthomosaic / Map with radiometric information

The principals of photogrammetry are well documented and need not be explained in detail, however with the continual miniaturisation and improved resolution of thermal cameras begs the question: Can you apply the same principals of photogrammetry to thermal images? The short answer is yes, however the idea becomes more difficult when you attempt to retain the radiometric information. Below is a workflow that will allow you to generate thermal Orthomosaic and retain the radiometric information.  Most radiometric sensors like the Tau 2 allow for 640×512 resolution .rjpeg images to be captured. The radiometric data however is not contained within the …
