Point cloud with intensity and without RGB.
Closed this issue · 1 comments
Greetings,
First of all, thank you very much for the effort put into this repository and the articles. It's really impressive. I just have a small question before conducting the experiment with my personalized data. I want to know if I can use it on my custom point cloud data that only contains XYZ + intensity information without RGB information, or on data that includes both RGB and intensity information. Thank you for your effort, I am looking forward to your response.
Hi @zeejja, thanks for your interest in the project !
Yes of course you can use any combinations of {XYZ, intensity, RGB}. Have a look at our already-implemented datasets and the corresponding configs to see how to handle your point attributes. For instance, DALES has XYZ+intensity, while S3DIS, ScanNet, and KITTI-360 have XYZ+RGB. None of those actually use both intensity and RGB, but it would be possible configure your dataset for it. To this end, have a look at the partition_hf
and point_hf
in the datamodule configs:
partition_hf
indicates the point attributes that should be used for the partition computationpoint_hf
indicates the point attributes that should be loaded from disk and used for learning
As long as your dataset's read_single_raw_cloud()
returns a Data
object with rgb
and intensity
attributes, implementing what you want should be straightforward.
Happy coding !
