Baffling camera alignment PhotoScan 1.2.3 vs MetaShape 1.5.4

[2bForgotten]

Hi there,

Because I have some trouble getting camera's well aligned in a project of around 300 camera's (sandy dunes with sparse vegetation as main subject) I am experimenting around to get the best results.

So I looked back in the archives to find PhotoScan 1.2.3 and installed it back.
I loaded the photo's (which come without GPS info) and got really nice alignment (40'000 - 4'000). Min/max error 0.184/0.677.
Project was then saved.

So I decided out of curiosity to just open the saved project in MetaShape 1.5.4.
To my utter suprise the camera errors reported now are terrible: min/max error 0.797/2.722

That is without having done anything to the saved project with just the camera's aligned. I cannot believe my eyes!

Does anyone know what's going on here?
I do know about the reports from the community about poor alignment performance in MS, that's what made me revert to PS in the first place.

Looking forward to your opinions,

regards,

Hello 2bForgotten,

Can you please share the projects processed in 1.2.3 and 1.5.4 with support@agisoft.com, so that we can study them?

Hi Alexey,

You mean sharing the whole photo set (3Gb)?
Given my poor internet connection, that would take me ages.   
Or do you mean some specific project files?

Hello 2bForgotten,

Project files with the alignment results only would be fine already.  At least for now.
