Error when launching monocular with TUM dataset

[diegomrt]

Hi,

I've just installed the tool and I'm trying to run the "freiburg1_desk" example from TUM dataset using monocular and TUM1.yaml. However, I'm getting an error, reproduced below. Any ideas about what could be happening?

I've renamed the rgb.txt file to files.txt and moved it into the /rgb folder.

Thanx in advance, Diego.

Hi,

It seems an error reading images from files.txt. This line should be a valid image path:

DIEGO_EJEMPLOS/rgbd_dataset_freiburg1_desk/rgb/#

Try to use an absolute path and check your files.txt, you can create it running this command inside rgb folder:

ls *.png > files.txt

Thanks Eduardo, I've just checked it is running! Indeed, it was a problem with the files.txt content. Relative paths seem to work well.

Diego.
