How do you obtain the instance label for each point?

[shuluoshu]

Hi, @laughtervv , @Rotch
Thanks for sharing you nice work. However, I wonder how to obtain the instance label for each point? Since S3DIS dataset only has semantic labels for each point ( 13 categories ) .
Besides, if you have already obtain the instance label for each point, what is the need for block merging?

Thanks a lot!

@shuluoshu ok good. Are you able to prepare dataset now?

I know the Stanford3dDataset, but I want to know how the author prepared this h5 file?

Thanks for sharing the prepared data set! I've noticed that points of different segmentation labels ('seglabel') sometimes have the same instance label ('pid'). Is this a bug?

@laughtervv The link to the h5 file is no longer valid. Can you share it again?
