To diagnose this problem, we need to see the error message log from the MultiviewStereoCL node. To view the log, select the MultiviewStereoCL node, and then click on the “Log” button in the lower right of the MeshroomCL window. Then, post the log error messages here and we can diagnose the problem.
One possibility is that you are running out of video memory on your video card. To test this theory, you could reduce the “Max Image Size” slider in the MultiviewStereoCL node attributes from the default value of 3200 to something much smaller, and see if the error goes away. But again, just show us the error log and then we’ll know what the problem is.
In the future, I’d recommend posting your MeshroomCL questions on the MeshroomCL GitHub site (https://github.com/openphotogrammetry/meshroomcl/). The developers of MeshroomCL will see your issue there and respond.
