Cannot complete photogrammetry

[canonex]

Hi,

I cannot complete the reconstruction because I receive the following error: ` ... 22:21:02 [App ] Scene loaded from interface format (206ms): 25 images (24 calibrated) with a total of 182.88 MPixels (7.62 MPixels/image) 4109 points, 0 vertices, 0 faces 22:21:02 [App ] Preparing images for dense reconstruction completed: 25 images (369ms) 22:21:02 [App ] Selecting images for dense reconstruction completed: 24 images (2ms) Estimated depth-maps 24 (100%, 19s981ms)

What can cause this error? If I import files in /tmp/OpenMVG/reconstruction_sequential I do find some interesting point cloud in ply!

Thank you! Riccardo

Hi @canonex !

Please, show me what have inside these two directories:

/tmp/OpenMVG/reconstruction_sequential /tmp/MVS

[canonex]

In /tmp/OpenMVG/reconstruction_sequential i have:

In /tmp/MVS I have:

Do you need a zip with the file contents?

Thank you, Ricky

Hi @canonex !

I saw the error, probably the problem is that the CPU or the memory did not was enought:

Segmentation fault (core dumped)

The new version of OrtogOnBlender have SMVS, maybe you can test it.

OpenMVG, OpenMVS, MVE/SMVS e Dicom2Mesh: https://goo.gl/Rqf1T4

Replace $Home/Program/OrtogOnBlender directory and install the last version of addon: https://github.com/cogitas3d/OrtogOnBlender

A big hug!
