Quality of Merged Chunks what time can improve? The next version?

We are working on this improvement, but it will take quite a time to implement. So it is not likely to be in the next update.

Hi,I tested the 15000 ? 15000, only 12 minutes the whole process, I  test 20000 ? 20000now

I can not open projects made with this version Build 1096 with Photoscan Build 985.

If the project has not been textured, I can see the model, but there is no info and its like I have to run the project again.

You're right

"This pre-release is considered as unstable and is not recommended for production use."

Worth knowing for people, and there might be an easy fix.

btw. most recent prerelease build is 1132
just wanted to throw this in because it is only mentioned in the changelog and many might have missed that.

Problem is still in this version as well.

Hello olihar,

Projects saved in 0.8.3 could not be opened in the previous builds but 0.8.3 opens projects from 0.8.2 for example.

Is there a reason why do you want to open new project in the previous build?
Also we are planning to update 0.8.3 in a few days.

[olihar]

Reason was I wanted to check if I was getting the same errors in Ground Control in the older versions. But then I ran a test in the older versions and got the same problem, I then posted it in the bug forum about the Datum.

Python support is greatly appreciated. It allowed us to programmatically add/remove photos and to copy transformation matrices between chunks. Combined with matrix multiplication, this gives a good programmatic control of alignment.

Some comments and requests:
- all operations on individual photos are rather slow (add/remove/select, en/disable), certainly for larger chunks (1000+ photos). It would help if we could provide a list of photos to each function e.g. doc.chunk(1).removePhotos(myList)

- camera control: get/set view X,Y,Z and view directions. Can be powerful combined with export in local coordinates since it gives fine control over the view. Alternatively an option to view and set the view from the GUI would be cool as well. Maybe on the status bar?

Keep on the good work,


Jan

Hello Jan,

Operations with photos are slow because GUI is updated after every operation with photo. Performing scripts from the command line should remove this slowness.
We are considering the implementation of GUI block function that also could solve the problem if scripts are run from GUI. Also Python functionality would be extended by time and I think it will include setting the camera view direction and position.
