Hello,  

I have been work on a better way to handle pano images from my Drone (Mini 
2), and one problem has me stumped.  

To help with the sheer volume of panos I am working with (~1000), I am 
attempting to script this with a Win Bat file file.  

The problem specifically now is with multiple images in a pano set being 
omitted due to no CP's found.  

Here are the script steps I am using to generate the CP's.  All other steps 
in my testing script have been remarked out to focus on this aspect of the 
problem - 

REM Build the PTO file with the contents of the directory we are currently 
in.
"C:\Program Files\Hugin\bin\pto_gen" *.jpg -o test.pto

REM Create Control Points in the existing pto file
"C:\Program Files\Hugin\bin\cpfind" -o test.pto test.pto

This works for most of the image sets, but being from the north and winter, 
I have many that are struggling with finding CP's when the contrast and 
features in the snow are not as obvious.  

Example Images -

I poured through the documentation on how to tweak cpfind to generate more 
points, but no matter what I have tried(Example: --kdtreesteps=1000 
--kdtreeseconddist=1 --sieve1size=500 --fullscale -v --linearmatch), I 
cannot force it to find more points in the snowy images.  

Any recommendations on how to tweak the process, and/or the cpfind command 
line options?

Thank you!
