- 用图像质量评估+自适应挑难样本,提升学习效率
- 在图像失真下仍保持高决策准确率
- 适合工业场景中视觉干扰多的机器人控制
智能控制技术的快速发展赋予机器人强大的自主能力。电缆布线作为工业中普遍存在的基础任务,是检验机器人灵巧性与序列决策能力的严格基准。然而,在实际场景中,图像观测常因信号失真而降低质量,低质图像样本会阻碍模型训练,影响智能控制系统可靠性与准确性。目前尚无专门针对图像信号失真的智能控制解决方案,且图像质量信息也未被充分用于提升控制性能。为此,我们提出一种新型机器人模仿学习框架,包含图像质量评估模块、基于置信度的学习机制和决策模块,可在图像失真条件下保持高性能。该框架通过图像质量评估模块提取观测图像的质量信息,结合置信度学习机制自适应筛选困难样本,以提升决策模块效能。决策模块负责选择合适的离散技能或连续动作。实验结果表明,所提框架显著提升了决策模块的整体性能。
原文摘要 · Abstract (English)
The rapid development of intelligent control methodologies has endowed robots with powerful autonomous intelligence. Cable routing, a ubiquitous foundational task in industry, provides a rigorous benchmark for robotic dexterity and sequential decision-making. In these practical scenarios, image observation distortion frequently occurs. Samples characterized by low-quality image observations often hinder accurate model training, posing challenges to the reliability and accuracy of intelligent control systems. Nevertheless, no dedicated intelligent control solution has been proposed for scenarios of image signal distortion. Meanwhile, image quality information has not been sufficiently exploited to further enhance the performance of intelligent control methodologies. To this end, we propose a novel robotic imitation learning framework that comprises an image quality assessment module, a confidence-based learning mechanism, and a decision-making module, which is designed to maintain high performance even under distorted image observations. In the proposed framework, the image quality assessment module synergizes with the confidence-based learning mechanism to enhance the efficacy of the decision-making module. Specifically, the image quality assessment module is incorporated to extract image quality information from image observations, while the confidence-based learning mechanism adaptively prioritizes challenging samples to improve learning effectiveness. The decision-making module determines appropriate discrete skills or continuous actions. Experimental results demonstrate that our formulated framework enhances the overall performance of the decision-making module.
