Meshroom 2023.2.0 - aliceVision_split360Images.exe

[Ryan Lin]

Hi 

I'm very excited to download the latest version released last month. I'm trying to test out the reconstruction result from sliced 360 images.

However, when I got an error message "ALICEVISION_ROOT is not defined, embedded OCIO config file cannot be accessed." when running this command on Windons: 

start aliceVision_split360Images.exe -i C:\Desktop\Sliced_360_Imgaes_Input — equirectangularNbSplits 32 -o C:\Desktop\Sliced_360_Imgaes_Output

does anybody know how to address this issue?

Hi,

You should not have this issue if you use the corresponding node in Meshroom.

You can manually define the ALICEVISION_ROOT to the top folder of alicevision (the one with "lib" and "bin" subfolders).

Best,

Thanks Fabien

I addressed this issue by setting up the environment variable of  "ALICEVISION_ROOT", however, I received another error message saying that "Embedded OCIO configuration file: 'C:\Desktop\Meshroom-2023.2.0-win64\Meshroom-2023.2.0/share/aliceVision/config.ocio' cannot be accessed." when running the same command with admin right. What should I do?

[Fabien Castan]

The ALICEVISION_ROOT should be the root folder of aliceVision:

Meshroom-2023.2.0\aliceVision\share\aliceVision\config.ocio

Hi Fabian

Thanks for your reply, I tried out your approach but still cannot make it work, here is my setting and steps, do you have any ideas where it goes wrong?

1. Setup environment variables ALICEVISION_ROOT for both User and System

2. Restart laptop

3. Use command prompt with Admin right to go to "C:\Users\lzlal\OneDrive\Desktop\Meshroom-2023.2.0\aliceVision\bin" 

4. Run "aliceVision_split360Images.exe -i C:\Users\lzlal\OneDrive\Desktop\MBC30_Sliced_360_Imgaes_Input — equirectangularNbSplits 32 -o C:\Users\lzlal\OneDrive\Desktop\MBC30_Sliced_360_Imgaes_Output"

5.  I still got the same error message "[0x00001cf0] [error]   Embedded OCIO configuration file: 'C:\Users\lzlal\OneDrive\Desktop\Meshroom-2023.2.0/share/aliceVision/config.ocio' cannot be accessed."

The problem is resolved. I misunderstood the meaning of root folder, thanks Fabien.

[Scott Howard]

I am having the same issue. What exactly is the root folder supposed to be set to?

[Marius Putrimas]

I can't figure out what I need to do with this ALICEVISION_ROOT... How to set this location?  I want to use this aliceVision_split360Images.exe file..

[Marius Putrimas]

Hi Scott, did you found the solution?

[Yuzheng K]

Hi Marius,

You can setup the environmental variable from Windows Settings - System -  About - Advanced system settings - Environmental Variable. As Ryan shows you should add ALICEVISION_ROOT to the variables, make sure the path end up with Meshroom\Meshroom-2023.3.0\aliceVision.
