Nothing in 3D viewer after StructureFromMotion

Hi Everyone,

I'm very excited to discover photogrammetry !

It's my first attempt to use Meshroom and I have an issue that I didn't manage to solve.

I have 195 Jpeg pictures with a resolution of 20Mpixel taken with my mavic 2 Pro and my goal is to create a 3D model of the ground in order to design a house.

After importing the photos I save the project then I click right on the "StructureFromMotion" node and then click on "compute". Each time, evrything goes without errors but nothig appears in the 3D viewer.

When I decide to press start to go further, the node "PrepareDenseScene" enconters an error and stops.

My PC Configuration :

- Inter Core i9-9900K @3.6Ghz

- 64 Go DDR4 @ 2133Mhz

- Nvidia GeForce GTX 1660 Super

To try to solve this problem, I have :

- tested with an other set of image

- instaled the latest drivers

- Force my GPU as primary with all Cuda proc for Meshroom

- reinstalled Python

But each time the same issue :

If you need more informations tell me.

Thanks by advance for your precious help :-)

Yannick

Are you using the official binaries from https://alicevision.org/#meshroom or a custom build?

Hi Fabien,

Yes, I am using the official binaries.

I have tried the last 2021.1.0 win 64 bit and the 2020.1.1 win 64 bit with the same issue.

I have also tried to compute my pictures in an other soft (MicMac) and it works.

My Nvidia GTX 1660 cuda GPU is well detected but seems to be not used from "CameraInit" to StructureFromMotion"

Here is the log of the first node. Should I try with other parameters than the default ones ?

Program called with the following parameters:

* contrastFiltering = Unknown Type "enum aliceVision::feature::EFeatureConstrastFiltering"

Maybe problems with non-ascii characters in the path of your scene.

Thanks Fabien for your help.

I have also tried that. I've changed my floder path from "2021-06-14-Acquisition_Double_Grille" to "20210614AcquisitionDoubleGrille" without any success.

OMG : thank you so mutch Fabien !

It's working now : I can see the StructureFromMotion in the 3D viewer !

I have not seen that the "é" of "photobrammétrie" (I am french) was still here.
