Hi Niels,
The FLIR DUO R has a 160 x 120 thermal resolution. This is a problem when trying to obtain an thermal mosaic: the flight path must be unacceptably tight.
My first approach was to use the radiometric jpeg images (1920 x 1080) and somehow retrieve a thermal mosaic from that those images, but from my understanding there's isn't a straight forward way to get the thermal data from radiometric jpeg unless using FLIR software. I guess this would be the best option, since the greater resolution of the RGB sensor would be enought to Photoscan processing.
Any suggestion on this approach?
Considering that the camera can shoot RGB + Thermal separately, what I'm trying to do now is process the RGB images with Photoscan, and with the model already built, change the image paths to the thermal ones, already scaled to fit the RGB size. The first problem is that the field of view (FOV) is different for both sensors.
I'll be working on this second approach.
