📝 摘要(中文)
身体运动在无法捕捉面部或语音的情况下传达意图。本文研究仅通过2D身体姿态识别交流意图,强调在需要实时、低成本的设备与机器人之间的长距离沟通场景(如救援任务)中,身体运动作为可靠信号的重要性。我们发布了一个涵盖十种交流意图的全身姿态数据集,并与其他真实和合成数据集进行比较。我们在有限的机器人硬件上评估多种模型,并报告性能指标和帧率,展示模型自回归自一致性作为无监督可靠性信号的有效性。
🔬 方法详解
问题定义:本文旨在解决现有方法未能有效识别身体运动信号的问题,尤其是在长距离人机交流场景中,缺乏针对性的数据集和模型评估。
核心思路:通过构建一个包含十种交流意图的全身姿态数据集,论文提出利用2D身体姿态进行意图识别,并引入自一致性作为无监督的可靠性度量,以提高模型的可靠性和准确性。
技术框架:整体架构包括数据集构建、模型训练和评估三个主要阶段。首先,收集和标注全身姿态数据;其次,训练多种模型(如骨架图分类器和关节运动预测网络);最后,在嵌入式GPU上进行性能评估。
关键创新:论文的主要创新在于首次将自一致性作为无监督的可靠性信号,提供了一种新的评估模型预测准确性的方法。这一方法与传统的监督学习方法形成鲜明对比。
关键设计:在模型设计中,采用了多种网络结构和损失函数,特别关注于如何在有限的计算资源下优化模型的帧率和准确性。实验中使用了NVIDIA Orin Nano作为嵌入式GPU进行性能测试。

📄 摘要(原文)
Body movement communicates intent at distances and in conditions where neither the face, nor speech can be captured. We study the recognition of communicative intent from 2D body pose alone. We argue that body motion is a reliable signal especially in scenarios that require real time low-cost on-device person-to-robot communication in long distance environments, such as rescue missions. However, existing resources do not isolate this signal. Affective corpora combine body, face, voice and text, while skeleton action-recognition benchmarks label the action performed rather than the message conveyed. We release a dataset of real frames of full-body pose covering ten communicative intents and we compare it against other real (IPC) and synthetic (MotionLCM, VEO3.1, Kimodo) ones that span a range of difficulty. We target systems that can run on a robot's limited onboard hardware. We benchmark multiple models, from skeleton graph classifiers to joint motion-forecasting networks, and report performance metrics together with frame rate on an embedded GPU (NVIDIA Orin~Nano), since speed matters as much as accuracy in our scenario. Finally, we show that a model's own autoregressive self-consistency works as an unsupervised reliability signal. We give a short proof that bounds the probability that a self-consistent prediction is correct, show that this probability grows with the number of consistent steps, and identify the conditions under which a confident prediction can still be false, benchmarked against industry-standard metrics.
