An error occurred when running the rgbd_renderer.py , the error message is as follows: Screenshot from 2021-05-20 15-17-34 I need the processing results of Linemod set to be used in FFB6D. Looking forward for your reply, thank you.

Have you solved it ? I meet the same problem. Thank you .

It seems that the length of self.bg_img_pth_lst is 0, maybe the path to the background image, the SUN2012pascalformat dataset is not set properly. Follow the README instruction: Download SUN2012pascalformat dataset from here http://groups.csail.mit.edu/vision/SUN/releases/SUN2012pascalformat.tar.gz. Unzip it and link the unzipped folder to this folder:

ln -s path_to_SUN2012pascalformat ./

hi @ethnhe

But the SUN2012 is a different dataset than LineMod right? So, while implementing this step , we need to generate rendered data using rgbd_renderer.py on LineMod dataset... and that gives an error.

Yes, SUN2012 is an RGB-only dataset for background generation. We randomly sample an image from SUN2012 and paste the foreground to that background. The related code is here from Line 170 to 197.

I got the idea of randomly sampling an image from SUN2012. But I get the same issue when I do it for Linemod dataset.

What I have done as of now is soft linked the dataset by ln -s path_to_linemod_dataset ffb6d/dataset/linemod/

What am I doing wrong here? any ideas? I am trying to train ffb6d model, but first I need raster_trianle script to render data, right?

Follow the README in this repo to set up and generate synthesis data

Sorry to disturb you again. I did exactly as the README suggested but the Linemod dataset and rgbd_renderer file are giving me this error mentioned above:

the fuse.py works fine, but not the rgbd_renderer. Any suggestions?
