Problem about nuscenes dataset

[liqiokkk]

Thank you for sharing code! I'm very interested in your excellent work! I I'd like to ask you some questions.
I visualized the nuscenes dataset (first image), but it contains lots of noise in black regions and different from the one (second image) in your paper.
In my understanding, black region is invisible regions of lidar (i.e., "~lidar_ray_mask" in your code?)
Could you tell me how to reduce these noises in black regions?
I look forward to your reply very much!!!

@liqiokkk ，I have see the lots of noise in another case when we try to change front image to BEW, could you tell me how to visualize the nuscenes?

Hi, here we followed the dataset generation method by https://github.com/tom-roddick/mono-semantic-maps.

If their maps do not look the same as their paper, then I think they might have changed their data generation code since.

Thanks for your reply.
I also follow https://github.com/tom-roddick/mono-semantic-maps, but it seems to appear the problem I described.
Could you upload ground-truth of the whole dataset?

@avishkarsaha can you upload your data generation code?

Please tell me how to get grouth truth for the whole dataset, I also follow https://github.com/tom-roddick/mono-semantic-maps but my output image is very noisy. Tks you very much

请告诉我如何获得整个数据集的真相，我也遵循 https://github.com/tom-roddick/mono-semantic-maps 但我的输出图像非常嘈杂。非常感谢你

Mine is the same as yours, has yours been resolved?
