Control Point Detection Test

I did this test in auto-everything using the Papywizard preset on both Apps… and looks like CPs generated in PTGui are better spread. I mean APG is still not able to detect CPs on the corners of the image with fisheye lenses.

I know I can do it manually but this is not the purpose of this test, which is to look for the best One-Click Pano Application.
Also missing points on the corners lead to poor stitching. I wonder if we can still see improvements on V3 in CPs detection. I hope so.

Re: Control Point Detection Test

Hi Marco,

you could play with the Ransac model settings and for more CP's you could raise the default 50 CP to 100.

Re: Control Point Detection Test

Thanks, I'll try... but as you can see from my pictures, CPs in PTGui are not only better spread, they are also less clustered.
I doubt there's an option for this along with raising the number of CPs.

Also I always use "Similarity". I don't know yet what Homography is but it's still too slow to do some testing.

PTGui is ok with clear structures but looses with chaotic or barely visible structures. Here APG is unbeatable . . cool

Sometimes it´s TOO sensitive and find CPs where none are visible - that doesn´t mean they´re not there . . cool

Vers. 3.0 got even better in finding CPs. I have PGTui also - but didn´t use it for months.

best, Klaus

Re: Control Point Detection Test

I'm starting to like APG with V3, that's why all these questions and critics... this is also the natural consequence of more use of APG. wink

You're right about PTGui... also, one thing I still don't like about PTGui is its blender (and using enblend is impossible; way too slow): did you noticed occasionally, mostly on the sky, the seams between images on the rendered pano. It's like a light and barely visible mark along the seams...

Re: Control Point Detection Test

i always thought that APG was specifically tailored for Gigas (ie a lots of photos) which would have quite a different setup to reg fisheye panoramics - which APP would handle quite well.
- am i completely wrong on this?

The name "Giga" is somewhat misleading - like the term "Auto" wink - there are several advantages over APP besides gigapixels. I mean APG definitely is preferable.
