Point Cloud Densification: An unknown error occured bad allocation

andrei.mirt · May 11, 2023, 4:19pm

I am trying to run densification on a project with 3250 images. I’m running it on a machine with 24cpus and 110GB RAM. The settings I need to use are:

Algorithm: Hardware accelerated (Nvidia T4 installed)
Image scale: 1/1
Multiscale: Off (I’d rather have accurate points at the 1/1 scale than more points)
Min matches: 6 ( I care more for accurate positions than more points of lower accuracy)
Noise filter: On
Sky filter: On

history.p4mpl

// Wed May 10 19:33:02 2023
CommandGraph {
GenerateSkyMasks {
}
GenerateGaPmvsDensePointCloud {
settings.imageDownscaleFactor : 0
settings.pointDensity : PointDensity.High
settings.minNbrOfMatches : 6
settings.multiScale : false
settings.denoise : true
settings.skyless : true
resources.useGpu : GpuUsage.Automatic
}
}
// Thu May 11 07:28:01 2023

// Thu May 11 07:47:55 2023
CommandGraph {
GenerateSkyMasks {
}
GenerateGaPmvsDensePointCloud {
settings.imageDownscaleFactor : 0
settings.pointDensity : PointDensity.High
settings.minNbrOfMatches : 6
settings.multiScale : false
settings.denoise : true
settings.skyless : true
resources.useGpu : GpuUsage.Automatic
}
}
// Thu May 11 15:42:50 2023
SaveProject {
}

After about 4 hours I am getting the following error:

An unknown error occured
bad allocation

What sucks the most about this error is that none of the 4 hours of work gets saved, so the Densification needs to be restarted from scratch.

I read in a different topic that the issue might be that there isn’t enough RAM, but according to the logs below, the RAM utilization was never at higher than 80% and when the error happened it was at about 50%. Does anyone have any idea of what the issue/solution could be?

Obviously, I could just try different settings, perhaps lower ones, but unfortunately, I’m not getting good enough results with lower settings, so that’s not a good solution for my situation.
Thinking that it may be simply configuration drifting, or a random error, I tried it twice, with almost identical results. Both failed a little bit after 4 hours.

@andrei.mirt,

I have a 64cpu system with 256 of ram. I can try processing it to quazi-eliminate whether it is or is not a ram issue. Let me know if that’s something that interests you and, if so, send me a link to the images.

andrei.mirt · May 11, 2023, 9:18pm

@Chris_Putnam

I appreciate your offer a lot. I started copying data to a location that I can share.
The raw-input is already there, but I’m also copying the pre-calibrated pix4d project, so that you don’t have to do the calibration as well, just the densification. It will probably take a few more hours from now until all the files of the project are there.

Actually, ideally, you would try processing on top of this calibration, because I think it may make a difference. Although, these are the only 2 tests I’ve tried with High Density (instead of the Optimal default) for densification, so maybe calibration doesn’t make a difference.

I would have tried with more CPUs/RAM, but Google doesn’t want to increase my vCPU quota for cloud processing for now, so I’m a bit stuck. Currently I’m trying again with 156GB of RAM, which is the maximum I can have (the previous tests were with 90GB and 110GB of RAM).

Sent you the link in the DM.

@andrei.mirt,

Thank you for including the Matic file. I meant to ask for that. I’ll process it as is, from scratch with your settings and, if need be, completely from scratch as a new file with your preferred settings. I’ll let you know what I find out. I’ll queue the first two options this evening. They shouldn’t take too long to process out. I am downloading the files now.

Hi @andrei.mirt

If you could share the entire log file that would be very helpful for us to troubleshoot.

Based on this error (Error) Densification failed I see in the partial logs you shared, some solutions for this issue include:

Depending on the size of the project, the hardware requirement is reached: Recommended hardware - PIX4Dmatic
Update GPU driver: How to update the driver for an NVIDIA graphics card - PIX4Dmapper
Ensure there is enough disk space in the hard disk
Ensure the project folder is not opened at the same time
Ensure the project folder + the dataset isn’t on an external drive or a network drive.

Just a friendly reminder, we also have a new release of PIX4Dmatic yesterday.

You can also try using the latest version. Before installing the latest version, please do a complete uninstall:

In the Windows Search, type Add or remove programs .
Scroll to find PIX4Dmatic and click the application.
Click Uninstall .
On the path where PIX4Dmatic was installed (default is C:\Program Files\Pix4Dmatic ), ensure this folder does not exist anymore. If it exists, DELETE this Pix4Dmaticfolder.
In C:\Users\Your Username\AppData\Local\pix4d , ensure the folder Pix4Dmatic does not exist anymore. If it exists, DELETE this Pix4Dmatic folder.
In the Windows Search type regedit and search for the folder stored in the path: HKEY_CURRENT_USER\Software\Pix4D and ensure this folder does not exist anymore. If it exists, DELETE this PIX4Dmatic folder.
Restart the computer.
Reinstall the latest preview version (v1.46.0) of the software: Technical release notes - PIX4Dmatic

Best,
Rosana (she/her)
