Can I fetch individual objects from the point cloud using this? about segmentanything3d HOT 8 OPEN

Any way you know of to get the semantic meaning in the point clouds?

I'm sorry I didn't understand your question. How do you want to fetch individual objects?

from segmentanything3d.

I want to have the coordinates of the segmented objects to possibly get a bounding box around them and get their semantic meaning.

With SAM3D, you can obtain the group_id for every point in a scene, as well as the coordinates in the original data. You may calculate the coordinates(max, min or mean) for each group.

Okay thanks! Another small query, the group_id represents a label or class in ScanNet dataset right?

Group_id just represents the group only, without any semantic information.

Would likely need to integrate something like this: https://github.com/IDEA-Research/Grounded-Segment-Anything

@yhyang-myron For example I want to get the coordinates of a chair in point cloud, is there anyway that might be possible?
