How do I know which room in the scene each box in bbox_3d.json corresponds to?

[Leon1207]

Does the "ID" in bbox_3d.json correspond to the room? Thanks!

The "ID" corresponds to the instance ID in instance.png.

Thanks for reply, so can I know which room in the scene each box corresponds to?

You can obtain this information by calculating the geometric relationships between the object bbox and the room polygon.

OK, thanks for your advice!
