UrbanGround 沙盒测试多模态大模型在真实城市导航中的能力

研究人员推出了 UrbanGround,这是一个新的沙盒环境,旨在测试多模态大语言模型(MLLMs)在真实、大规模城市复制品中的空间推理和导航能力。该系统使用基于大量地理空间数据构建的香港三维模型,来评估 MLLM 代理在复杂城市环境中将局部感知转化为持续、目标导向行为的能力。初步研究结果表明,尽管当前 MLLMs 在即时视觉识别和短距离空间任务方面表现出色,但在扩展探索过程中保持可靠性能方面存在困难,错误会累积,并且行人移动等动态环境变化带来了重大挑战。 AI

影响 突出了当前多模态大模型在现实世界导航中的局限性,为具身人工智能和空间推理的未来研究指明了方向。

    UrbanGround:从局部感知到真实城市规模的空间能动性

    UrbanGround evaluates whether multimodal language model agents can sustain reliable navigation and spatial reasoning in a realistic 3D city replica, revealing that local perceptual skills fail to compose into extended goal-directed behavior.

    UrbanGround:从局部感知到真实尺度城市中的空间能动性

    arXiv:2608.27456v1 Announce Type: new Abstract: Multimodal large language models (MLLMs) can interpret a street view, but urban agency depends on whether such local evidence remains useful after the agent starts to move. In this paper, we investigate how far current MLLM agents c…
