What does the 3rd labels of point mean in instance segments? #29

I found there is a 3-dims labels per point, first is the class-id, the second is instance-id, but I don't know the 3rd dim means. I guess it may be able to be named as "segment-id". because it usually generates items like "point2segment","segment2label". So, what does the 3rd dim in point's labels mean, or what does the segment represent?

Hi!

Yes, you are right. This column is used for the segment id (if provided). Find more details here.

Best, Jonas
