Hello Alexey,
yes, that could be the last possibility.
Is it possible, that the filter of depth maps in version 1.7.3 is clearly higher/more aggressive than in 1.6.5?
I have the feeling, that I generate clearly worse results with UltraCam images in 1.7.3 than in 1.6.5. Additionally, the processing time of the depth maps increased by factor 3 and of dense cloud by factor 1,5 to 2.
In the moment I am calculating the same project, which I already have with very good results- This was done with version 1.6.5. Than I can see the difference in detail.
I will send you an email, maybe you can calculate the results as well.
Probably, only my working group is working with UltraCam images, so that could be a special problem.
