摘要:

定位自然语言描述的物体对自主智能体而言是一项重大挑战。现有基于CLIP的开放词汇方法能够利用简单(bare)查询成功执行3D物体定位,但无法应对需要理解物体关系的模糊描述。为解决该问题,我们提出了一种名为BBQ(Beyond Bare Queries)的模块化方法,该方法构建具有度量与语义空间边的3D场景图表示,并通过我们的演绎场景推理算法将大语言模型用作人机交互接口。BBQ采用鲁棒的DINO驱动关联来构建3D以物体为中心的地图,并使用先进的raycasting算法配合2D视觉-语言模型将物体描述为图节点。在Replica和ScanNet数据集上,我们证明了BBQ在开放词汇3D语义分割方面相比其他零样本方法处于领先地位。此外,我们还表明利用空间关系对于包含多个同一语义类别实体的场景尤其有效。在具有挑战性的Sr3D+、Nr3D和ScanRefer基准上,我们的演绎方法展现出显著改进,相比其他最先进方法能够通过复杂查询实现物体定位。我们的设计选择与软件实现的结合在机器人机载计算机实验中带来了显著的数据处理速度提升。这一有前景的性能使我们的方法能够应用于智能机器人项目。我们已在https://linukc.github.io/BeyondBareQueries/公开代码。

英文摘要:

Locating objects described in natural language presents a significant challenge for autonomous agents. Existing CLIP-based open-vocabulary methods successfully perform 3D object grounding with simple (bare) queries, but cannot cope with ambiguous descriptions that demand an understanding of object relations. To tackle this problem, we propose a modular approach called BBQ (Beyond Bare Queries), which constructs 3D scene graph representation with metric and semantic spatial edges and utilizes a large language model as a human-to-agent interface through our deductive scene reasoning algorithm. BBQ employs robust DINO-powered associations to construct 3D object-centric map and an advanced raycasting algorithm with a 2D vision-language model to describe them as graph nodes. On the Replica and ScanNet datasets, we have demonstrated that BBQ takes a leading place in open-vocabulary 3D semantic segmentation compared to other zero-shot methods. Also, we show that leveraging spatial relations is especially effective for scenes containing multiple entities of the same semantic class. On challenging Sr3D+, Nr3D and ScanRefer benchmarks, our deductive approach demonstrates a significant improvement, enabling objects grounding by complex queries compared to other state-of-the-art methods. The combination of our design choices and software implementation has resulted in significant data processing speed in experiments on the robot on-board computer. This promising performance enables the application of our approach in intelligent robotics projects. We made the code publicly available at https://linukc.github.io/BeyondBareQueries/.
