Interactive scene segmentation for efficient human-in-the-loop robot manipulation

摘要

While there has been tremendous progress in autonomous robot manipulation, environments with clutter and unknown objects remain challenging particularly for the perception algorithms that support manipulation. This paper adopts a human-aided perception paradigm and investigates alternative interactive segmentation methods to allow users to segment a target object or object part. Through a first user study (N=24) we compare four interactive segmentation methods and characterize the tradeoff between efficiency and accuracy. Next we develop a hybrid segmentation interface and integrate it into an end-to-end human-in-the-loop manipulation system. In a second user study (N=12) we compare the performance of this system to a direct gripper-control system that allows similar manipulation tasks to be performed in challenging scenes. We find that this system enables more efficient manipulation with a lower mental load on the user, while offering a similar task success rate.
