About the SemanticKITTI-DVPS label names. #8

Closed HarborYuan closed 3 years ago

HarborYuan commented 3 years ago

Hi, Thanks for your great work. Currently, I am working on my own project on SemanticKITTI-DVPS. I am wondering what is the label names of the dataset, since it seems different from both the Cityscapes and the original Semantic KITTI datasets. Can I find the name corresponding to each class id in some place?

Thanks.

Hi @HarborYuan

Thanks for the question. The SemanticKITTI label names can be found here:

https://github.com/PRBonn/semantic-kitti-api/blob/master/config/semantic-kitti-all.yaml#L144

The difference is that in SemKITTI-DVPS we make 255 unlabeled, and shift the rest IDs by 1, i.e., 0: car, 1: bicycle, 2: motorcycle, and so on.

Hope it helps.

Thanks for your response. And I guess the "moving" classes are merged (so that 0-18, 'car' to 'traffic sign' are valid classes), while 0-7 ('car' to 'motorcyclist') are things, right?

Yes, that's correct.
