symmetry objects

Closed this issue · 1 comments

Hey @j96w , thanks for your great work. I finaly get really good results.
I still have one question left : What kind of symmetry is meant in the dataset.py file in ycb?
self.symmetry_obj_idx = [12, 15, 18, 19, 20]

I dont get why the bleach cleanser is a symmetrical object and the sugar-box or a can not? I hope you can help me with that.
Best Regards Ixion

Hi, so to be honest, the definition of symmetry objects are from prior works like PoseCNN. I'm not sure about the exact definition but I think they have taken the texture and color into consideration. For some objects like the sugar-box, you can tell which surface (front or back) is visible in the camera image by its testure.
