1.5 worse then 1.4.5 at aligning drone images

[aaronfhd]

I have a set of images that I went to align and it did not align all of the them in 1.5

In 1.4 they had no issue.  I have to now manually go in and align the cameras which align with no problem after the initial alignment.

Why would it be worse? it should be better with the upgrade.

Attached is a example of the drone images not aligning and only some of them do.

This is in 1.5.0

In 1.4.5 I never ran into this issue.

Hello aaronfhd,

Is it possible to share a problematic image set with use (via support@agisoft.com), so that we could perform some internal tests to see the difference between the versions?

Also do you observe the problems, when using only Reference preselection option without Generic in the version 1.5.0?

[aaronfhd]

Both Are selected.

I have reverted back to 1.4.4 for now so I can get my work done. 

Once I have that I will be able to compare.

Alexey,

I can sort of confirm that the new Generic preselection optimisation introduced in Build 7125 may have slightly impacted to alignment quality when the option is turned on. It's not always 100% reproduceable.

2 weeks ago when I did it in 1.5 all 81 cams where aligned but the sparse coud only represented the top part of the tree. There was no points anywhere else (no base of the tree no floor nothing at all.)

With generic preselection off in 1.5 it looks good (exactly like the 1.4.5 screenshot below)

Cheers

ps: I dont' have access to the photoset right now to send it to you.
