Bug Reports / Incremental image alignment on 1.8.3

« on: June 23, 2022, 05:19:33 PM »

Hi,
Are there any known issues with incremental image alignment on 1.8.3?
I have recently upgraded and I am taking a model built using 1.7.5, and I am trying to add a new set of images.  However the software is not doing any point detection and simply reporting that a number of images have not ben aligned.
Thanks in advance
John

Bug Reports / Re: Blending Textures not using GPU

« on: June 21, 2022, 10:41:27 PM »

Hi Alexy,
If a fix is not available yet, maybe you can kindly suggest a work around, maybe to revert back to a specific combination of versions of Metashape and graphics drivers that do not demonstrate this problem?
Thanks and regards
John

Thanks Alexey!  Looking forward to a quick fix (I'm a little stuck trying to conclude a project at the moment!)
Best regards

Hi Alexey,
I cleared the log and restarted Metashape so what you see in the attached is the following:
1. Startup lines
2. Build mesh process where you can see the GPU is being used.  I aborted the process
3. Build texture process whereyou an see the same message I sent originally (GPU detected but not used).  In this case also I aborted the process
I can confirm that there are no tweaks at all in place
Thanks
John

Bug Reports / Blending Textures not using GPU

« on: May 19, 2022, 08:10:14 AM »

Hi
I am using the latest Metashape (1.8.3 build 14331) on a windows laptop with AMD Rhyzen CPU and a 3080 Laptop GPU. I have also upgraded to the latest Nvidia driver version 512.77.  I did this in an effort to sold this problem but the problem remains.
When running textures I am getting the following

Code: [Select]

Found 2 GPUs in 0.483 sec (CUDA: 0.224 sec, OpenCL: 0.259 sec)

General / Re: Error message "Incompatible keypoints"

« on: April 13, 2021, 04:56:21 PM »

Hi Alexey,

Out of 5 previous alignments for 4 of them I was on 1.7, specifically 1.7.0.11736 and 1.7.1.11797.  I  was on 1.6.5.11249 only for the very first model.  I had no such errors aligning chunks using the same approach up until my current version which is 1.7.2.12070.  So could it be the case that the incompatibility was introduced in 1.7.2? 

In that case is it possible to either:
(a) download 1.7.1.11797 and continue working with this version?
(b) rebuild the alignment for just the first 1.6.5 chunk using 1.7.2 and move on from there?

I prefer option (b) of course

Thanks and regards

John

Thanks Alexey.  That could be it, I have had to do a full windows reinstall of my machine recently and although I am very certain that I was previously running 1.7, I could be mistaken.  Is there any way to check the version that the models were previously built on? 

Is there a way to "upgrade" the models to the new version or is the only option to remain on 1.6 for this model?

Thanks

General / Error message "Incompatible keypoints"

« on: April 12, 2021, 06:53:44 PM »

Hi,
I have been working on a rather large model of some underwater topography.  One of the steps of the process I am following involves adding cameras from a dive to a previous model (which is made up of all previous dives), and to then use a camera based alignment of the previous (accumulated) model to the new model (of the last dive) for the production of a rough model to help me to understand which areas are covered and which need further dives. 
When attempting this with my last data set I get an error "Incompatible keypoints".  The process I am following has worked fine for the first 7 dives so I cannot quite understand why I am encountering this problem now.  Any ideas would be appreciated.
Thanks and regards
John

Feature Requests / Re: Reduce the number of photos (both Standard and Pro)!!!!

« on: May 26, 2019, 03:57:19 PM »

Is possible delete the disabled images with the reduce overlap tools without check one by one in case of big dataset?

This is a question I have also
Thanks!

Python and Java API / Script to disable every "nth"camera

« on: May 24, 2019, 05:02:56 PM »

Hi,
I am working with some large datasets provided to me by somebody else.  On examining the images I realize that the amount of overlap is unnecessarily large,which will of course lead to unnecessarily long processing times.  Maybe there are other ways of tackling, however one way could be to run a script to disable every nth image (n could be maybe between 2 and 4) before running alignment.
I wish I was able to use python but I have not picked it up yet.  I was hoping that somebody can provide a script to do this?
Many thanks!

General / Manuals and installers for previous versions

« on: May 19, 2019, 09:40:30 PM »

Hi,

Apologies if I am missing something, but are manuals and installers for older versions of Photoscan available for download.  I tend to use different versions for different parts of my workflow, and having ready access to a number of releases and their manuals would be very useful.

Thanks

General / Bad Allocation error during mesh generation in 1.4.5

« on: April 13, 2019, 03:22:37 PM »

Hi,

I am having this error coming up when running a mesh generation using the "consistent visibility mesh generation method" in 1.4.5, which I have had good success with in the past.

I am running on a highly specced VM on google cloud - 64 CPUs, 4 x Tesla P100, 256Gb RAM,  This is an expensive setup and it is pretty annoying that after running for around 20 hours I get this message!  Lots of money down the drain!

There was a solution posted here around increasing virtual memory which I have done, however before restarting the process only to have the same problem I was wondering if anyone had any further suggestions?

My model consists of around 2,400 24megapixel photographs.  Does anyone know the recommended memory required for such a size?

Many thanks!
