AI总结:

针对协作机器人3D语义分割数据集不足问题,提出专门数据集COVERED,并提供SOTA算法基准,利用多激光雷达系统实现实时语义分割,准确率超96%。

摘要:

随着新兴的工业5.0范式出现,安全的人机协作(HRC)近期引起了广泛关注。传统机器人正被更智能、更灵活的协作机器人(cobots)所取代。cobots与人类之间安全高效的协作在很大程度上依赖于cobot对工业环境动态周围环境的全面语义理解。尽管语义理解对此类应用非常重要,但协作机器人工作空间的3D语义分割仍缺乏充分的研究和专门的数据集。由数据集不足引起的性能限制被称为“数据饥饿”问题。为了克服这一当前限制,本工作开发了一个专门为此用例设计的新数据集,名为“COVERED”,其中包含机器人单元的逐点标注点云。最后,我们还提供了当前最先进(SOTA)算法在该数据集上的性能基准,并演示了使用多激光雷达系统对协作机器人工作空间进行实时语义分割。在实时动态变化场景中使用训练好的深度网络所取得的令人鼓舞的结果表明,我们的方向是正确的。我们的感知流水线实现了20Hz的吞吐量,预测点准确率大于96%,平均交并比(mIOU)大于92%,同时保持8Hz的吞吐量。

英文摘要:

Safe human-robot collaboration (HRC) has recently gained a lot of interest with the emerging Industry 5.0 paradigm. Conventional robots are being replaced with more intelligent and flexible collaborative robots (cobots). Safe and efficient collaboration between cobots and humans largely relies on the cobot's comprehensive semantic understanding of the dynamic surrounding of industrial environments. Despite the importance of semantic understanding for such applications, 3D semantic segmentation of collaborative robot workspaces lacks sufficient research and dedicated datasets. The performance limitation caused by insufficient datasets is called 'data hunger' problem. To overcome this current limitation, this work develops a new dataset specifically designed for this use case, named "COVERED", which includes point-wise annotated point clouds of a robotic cell. Lastly, we also provide a benchmark of current state-of-the-art (SOTA) algorithm performance on the dataset and demonstrate a real-time semantic segmentation of a collaborative robot workspace using a multi-LiDAR system. The promising results from using the trained Deep Networks on a real-time dynamically changing situation shows that we are on the right track. Our perception pipeline achieves 20Hz throughput with a prediction point accuracy of $>$96\% and $>$92\% mean intersection over union (mIOU) while maintaining an 8Hz throughput.
