Hi Triess, I have read your paper and was very impressed. I am currently working on a paper for panoptic segmentation on semanticKITTI and would like to try your scan-based projection approach.
Just wondering is there any plan on releasing the code?
Thanks.

I am using your code on the semanticKITTI dataset, and function: unfolding.projection() raise the following error:

"Cannot find valid image indices for this point cloud and image size. "
IndexError: Cannot find valid image indices for this point cloud and image size. Are you sure you entered the correct image size? This function only works with raw KITTI HDL-64 point clouds (no ego motion-corrected data allowed)!

This unfolding.projection() works as expected on the provided "sample_raw.bin".
And I am using ".bin" files from the semanticKITTI dataset.

Are there any changes that I need to make to use your code on the semanticKITTI dataset?
Thanks in advance.

Hi Larissa,

First of all, thanks for sharing this code to public. I saw that the projection is so beautiful, it doesn't have a blank rows at the bottom half of the range image. I appreciate that.

I have a question,Is there any option to reproject back to point cloud type? I have tried using another code which uses static vertical resolution, but it is not aligned well with the original pointcloud.

Hope hearing from you soon. Thanks

Hello. I want to ask about the 3D rings you draw in Figure 2. How do you draw figures like this? What software did you use? This figure looks very beautiful. Thanks :)

Would you please elaborate on function GetRows? Confused of what the function is going to output. Is it a scalar or a list? Appreiciate it

Thanks for your work! Can you share how the image below was drawn?This will be very useful for me！
