Feature Requests / Please update date of main project file with each save
« on: December 03, 2017, 10:27:37 PM »
Like the title says:
While this can be avoided with a strict naming regime, it could avoid possible mixups and mistakes if the main project file was updated with each saving progress.
Point in case: I just suffered a minor heart attack when I had to kill the Photoscan process and the last modified date of the project file seemed to be from hours ago. But it could also happen that people continue to work with the wrong version of their file.

(Using the beta, here, didn't double check with an older version.)

General / Flush memory between batch steps
« on: June 29, 2017, 07:19:06 AM »

Is there a possibility in the none pro version to do some kind of garbage collection or flush the memory between batch processing steps? Delete the undo buffer or cache?
Agisoft seems to eat memory over time or at the very least isn't releasing part of what it used for previous steps, which makes sense if I want to access the parts again shortly, but when I have a file with several chunks and try to process them in a row, the baseline of RAM used is continuously rising. job after job, ultimately leading to failed jobs. If I close and reopen the file, it uses a lot less RAM again.

General / Photo aligning with two groups, but not at the same time
« on: November 10, 2016, 04:23:58 AM »
This is more out of interest for the inner workings of Photoscan than anything else, but I've repeatedly found myself in a situation where Photoscan can't align a couple of cameras, but can align these cameras among themselves if I start with them.
Which makes sense, of course.
(Group meaning simply group, here, not any special function of Photoscan.)
But more interesting and the point of my question: Sometimes there are photos which will align with either of the groups, but not at the same time. (So if photo B aligns with group A it's no longer possible to get group C to align with photo B, which is possible if photo B is on its own.)

The photos are of pretty poor quality, so it's not a big deal and the obvious answer is to shoot better and more photos, I just wonder what might be the problem, here. There is no zoom or movement of the object itself happening, as far as I can tell. (Unfortunately I can't share the photos.)

General / Lock viewport camera?
« on: November 08, 2016, 05:28:25 AM »

Is there a way to lock the viewport (camera)?

Right now when I e. g. align additional cameras, the viewport is reset every time.
I'd like to keep my current view at the point cloud to be able to judge changes.

Feature Requests / Save workflow parameters/options with file
« on: November 06, 2016, 04:31:53 PM »
I'd prefer to see the last parameters that were used to create each workflow step of that specific project when opening a file, not the last parameters that were used for the last project that might be completely unrelated. (Alternatively the parameter info could be saved extra and easily accessible e. g. by right-clicking Tie Points, Dense Cloud, or 3D Model in the Workspace. Maybe something like that exists somewhere already?)

I realize this is partly a user error, since you can always save, but I often find myself wanting to cancel one of the workflow steps and still find the previous solution. This might be down to memory consumption, but the regular behavior (in my opinion) should be to replace the old solution only if there is a new solution.
For example, as a relatively inexperienced user, I often play around with the settings of one of the workflow steps to check them out or prepare them for the next calculation and accidentally hit "OK"  (Which could be renamed to e. g. "Start calculation") since there is no button to confirm the settings without starting a calculation and if I cancel that (potentially very lengthy) calculation, I've lost a potentially very lengthy calculation without being able to undo that.

General / Identifying moving objects
« on: October 25, 2015, 07:37:37 PM »
I'm doing my first steps with Photosca, and despite having only a mediocre camera, right now, the outcome is surprisingly good after learning the basics.

Here is a problem I'm currently facing, which ultimately can be traced back to bad input images, but I'd like to salvage the project if possible.

I shot a scene with a lot of  leaves on the ground. I should have removed them probably, but there was no wind when I started to shoot and they looked nice. Mid shooting, there were some small gusts of wind. Not enough to disturb the scene a lot or even move most of the leaves, but some probably changed. I was in a hurry and didn't reshoot.

Now the images aren't of the best quality, but most of the cameras get aligned fine. Some don't . I suspect it's because of the moving leaves. Since there are a lot of leaves, I thought it would be handy if Photoscan could give me some indication of which images would align if it wasn't for some problem areas and could identify the problem areas somehow so I could mask them out.

Is this possible and would you say I'm judging the situation correctly?

I know about thinning the tie point cloud with the various gradual selection methods, but I can use them only if the camera has been aligned in the first place.

I'm using Photoscan Standard Edition.
