摘要:

在文献中,已经将使用多模态感知(诸如视觉和触觉感知)的准确的物体位姿估计用于自主机器人操作器。由于视觉和触觉数据的密度变化,我们以前提出了一种新的概率贝叶斯滤波器为基础的方法,称为姿态不变四元数滤波器(TIQF)的姿态估计。由于触觉数据汇集是耗时的,因此主动触觉数据汇集通过推理多个潜在动作以获得最大预期信息增益而被优选。在本文中,我们经验性地评估各种信息增益标准的背景下,物体姿态估计的动作选择。我们证明了我们提出的TIQF姿态估计方法与各种信息增益标准的适应性和有效性。我们发现在所有选定的标准与稀疏测量的姿态精度方面的性能相似。

英文摘要:

Accurate object pose estimation using multi-modal perception such as visual and tactile sensing have been used for autonomous robotic manipulators in literature. Due to variation in density of visual and tactile data, we previously proposed a novel probabilistic Bayesian filter-based approach termed translation-invariant Quaternion filter (TIQF) for pose estimation. As tactile data collection is time consuming, active tactile data collection is preferred by reasoning over multiple potential actions for maximal expected information gain. In this paper, we empirically evaluate various information gain criteria for action selection in the context of object pose estimation. We demonstrate the adaptability and effectiveness of our proposed TIQF pose estimation approach with various information gain criteria. We find similar performance in terms of pose accuracy with sparse measurements across all the selected criteria.
