MvgMvs_Pipeline.py and exe files crashing

[AkashGutha]

I wanted to know if I can directly use the executable in the sample rather then building from openMVS source code. I tried executing densifypointcloud on the scene.mvs given in sample but the file keeps crashing, could you guide me whether the approach is correct or not ?

[cdcseacave]

The sample might be old, I'll update it and let you know.

[AkashGutha]

Sure. thank you so much.

[cdcseacave]

Done, pls check again.

I got the same issue on Windows10 x64 system.
it always crash at running DensifyPointCloud.exe even with the newest release.

I have the same issue on a Windows 7 SP1 x64 VM in linux as well. The program crashes after the line Command line: ...
Do you need any dependencies to run these binaries? like .NET or something else

[cdcseacave]

no

Hi folks! Unfortunately, I encountered the same issue. All exe's crashed immediately on native Win7 SP1 64bit. Then I tried Win8 where I got the same log output as AkashGutha reported. Is there a way to get more debug info??

Btw I failed to build from source, since vcpkg installation didn't work at all for me :(

[cdcseacave]

hard for me to find an explanation for these problems with only this info; myself I never seen something similar, plus I know tens of people successfully using this build on their won machines

if having issues with the windows install, pls create an issue on openmvs

Hi, thank you for the quick answer. I solved the win8.1 problem! The nvm file contained filenames of images with whitespaces. Everything works fine now on that machine.

I am, however, wondering how I could debug the issue on the win7x64 machine (a powerful server) where any of the exe files in this sample crashes immediately without any output?

[isolin]

I finally found the answer to the second problem as well. The win7x64 machine has a pair of Xeon X5550 processors that do not support AVX instructions. Are those necessary for openMVS, or would it be possible to create binaries for processors without?

[cdcseacave]

AVX is not mandatory, it only increases the speed. You can disable that from CMake configuration.
