Information on processing thermal imagery with WebOMD

Hello, I am a total beginner trying to create a thermal orthomosaic map and overlay this on top of a normal RGB orthomosaic map. After installing WebOMD on Linux Mint 19.3, I can do the normal RGB stitching pretty well so right now I want to extend and use the thermal camera to create a more extensive map.

My question is how do I achieve to create this thermal orthomosaic using ODM? Would the images taken from the thermal cameras geotagged with the location they were taken be enough for this, or would I need to somehow use the transformations done to the RGB images on the thermal images? Is there a better way to do this? In addition, would thermal images of resolution 206x156 be enough for this?

Thank you in advance.
