Hi,
I'm trying to create a thermal orthomosaic from imagery captured with the Flir Duo Pro R.
The imagery is captured at 40m AGL, taken using 1sec intervals, flying at speeds of 15km/h, flying along rows of solar panels. Overlap of these images is really high, 80% or more. The final image works out to be a Radiometric Jpeg file containing radiometric data (temperatures for each pixel).
I am looking for a workflow or instructions on how to use this imagery to process an orthomosaic and use a thermal mesh to display as a thermal layer perhaps over the rgb orthomosaic.
The beauty of the Flir duo pro R is that the images are taken at the same time, two lenses and the final RGB imagery once the full photo is extracted from the RJPG becomes 4000x3000 pixels. So it is relatively high. The thermal sensor resolution is 640x512 pixels. According to a few forum posts, I gather you can potentially stitch the RGB, and then overlay the thermal layer (lower resolution so harder to stitch straight up) on top of the surface model?
Please can someone help point me in the right direction to be able to create a thermal orthomosaic from this imagery. I have tried to use pix4d trial version - as they have instructions regarding thermal imagery in their support section, but I would like to use agisoft photoscan, as this is what we use for all our other processing.
I do have other imagery where by I flew the same area at 80m above ground, with 80% overlap and 85% front lap in a grid pattern, pictures every 1second, captured using drone deploy to fly the grid at a consistant speed.
