Freeze at the end of reconstruction realitycapture version 1.4

I was on version 1.3 without bugs (at less not too much). But, since the new 1.4 version, there are a lot of freezes especially at the end of the reconstruction. For example, for my current project, the program runs normally and generates the parts. When you reach 99% or a little less, the program seems to be crashed. If I try to pause, the program records but nothing happens. The only solution is to start all over again and hope it doesn’t crash again.

Hi, did you try processing some projects that you have already done in 1.3? It is common for RC to slow down at certain points in processing, try making a console view to see what is happening when it is paused.

Thank you for your answer, Wallace.

Yes, but pausing since 10 hours or plus, it is not a pause anymore :slight_smile:

I make the same process that with the 1.3 version. Theses buggs are totally new (freeze just before the end - around 95% / 99% ). The processor (i9) is about 30% for realitycapture so it seems to be in action but nothing change and for example, the message says “ending in 25 secondes” during hours.

So, i redo the process to the begining. Sometime, the process go the end whithout any trouble and sometime it failt. I delete all the cache and retry. But it is not change the result.

Another new bugg is the the message : “a depth-map for filtering is corrupted”. I work with the same style of photos with the same camera and the same process. I had never this message on the 1.3 version.

So, i must retry my process 2, 3 or more times to have a chance to succeed.

Hi, can you try to use Version 1 under MESH MODEL/Create Model/Settings/Advanced?

Hi Otrhan.

This is my actual process below:

  1. i import my photos with the input button of the workflow tab
  2. I go the the tab alignement and launch the alignment with align images button
  3. i go to mesh model tab and press “normal detail” button to launch the reconstruction.
    I have no controls points.
    Current project : 600 images X 20 megapixels each

@godardp
have you tried that Version 1 setting?
This is strange, as there weren’t any changes in the reconstruction settings between versions 1.3.2 an 1.4.

Hi Hondrej.

I worked yesterday on another project. Medium size (500 photos x 20 mp).
Version 1.4 of realityCapture.
Alignment was ok, no control point needed.
The first try on reconstruction failed because a depth map filter error.
So, i retry.
Second try, the reconstruction was ok but at 96%, it was blocked for hours.
So, i deleted all the files in the temps directory and try again.
And the reconstruction was finally ok. I am so happy when it is ending but what a wast of time.
My drivers for Nvidia are updated.
What is strange, it that my I9 Intel processor work at 20-25% for Reality Capture between this time (when the process seems stopped) and my Nvidia card is about 0-5%.
I have 64 GO of memory. The % of memory used is very low at the same time (maybe 5%).

Sorry Ondrej. I just have understand your request. i will change Deepth map algorithm version 2 for the 1 version and i will test it.

Hi Ondrej.

Update on my crashs.

Perhaps my crashes can partly be explained by my settings. I had chosen to greatly increase the “max features per mpx” and “max features per image”. I reset the settings to default. I have fewer crashes.
