resolution of this camera is only 80 x 60.
Far too low to get any serious results.
I did some test with a "top of the range" FLIR camare, having 640 x 480 pixels, and the results were very poor.
The best solution I found so far is to combine the flir camera with an optical one (high res), build the model from the optical images and apply the textures from the thermal images. To do so, you have to "warp" each thermal image on the corresponding optical one.
