I have purchased the FLIR Vue Pro camera and made some tests. Unfortunately, I am not able to achieve a good quality orthophotomap. I have prepared everything very precisely and have no idea how to make a good quality materials in Pix4D.
I use FLIR cam with 19mm lens and make photos in TIFF format with 90% overlap and 75% sidelap. I make a manual georeferencing.
Hope to get any advice from you.
