摘要:

最近,社区已经见证了许多为开发和测试状态估计器而构建的数据集。然而,对于一些应用,如空中运输或搜索和救援,接触力或其他干扰必须被感知到鲁棒规划和控制,这超出了这些数据集的能力。本文介绍了一个视觉惯性动力学(VID)数据集,不仅关注传统的六个自由度(6-DOF)位姿估计,而且还提供了飞行平台的动力学特性,用于外力感知或动力学辅助估计。VID数据集包含硬件同步图像和惯性测量,具有用于评估常见视觉惯性估计器的精确地面实况轨迹。此外,所提出的数据集突出了转子速度和电机电流测量、控制输入和地面实况6轴力数据,以评估外力估计。据我们所知,拟议的VID数据集是第一个包含真实世界中的视觉惯性和完整动力学信息的公共数据集,用于姿势和外力评估。数据集:https://github.com/ZJU-FAST-Lab/VID-Dataset和相关文件:https://github.com/ZJU-FAST-Lab/VID-Flight-Platform是开源的。

英文摘要:

Recently, the community has witnessed numerous datasets built for developing and testing state estimators. However, for some applications such as aerial transportation or search-and-rescue, the contact force or other disturbance must be perceived for robust planning and control, which is beyond the capacity of these datasets. This paper introduces a Visual-Inertial-Dynamical (VID) dataset, not only focusing on traditional six degrees of freedom (6-DOF) pose estimation but also providing dynamical characteristics of the flight platform for external force perception or dynamics-aided estimation. The VID dataset contains hardware synchronized imagery and inertial measurements, with accurate ground truth trajectories for evaluating common visual-inertial estimators. Moreover, the proposed dataset highlights rotor speed and motor current measurements, control inputs, and ground truth 6-axis force data to evaluate external force estimation. To the best of our knowledge, the proposed VID dataset is the first public dataset containing visual-inertial and complete dynamical information in the real world for pose and external force evaluation. The dataset: https://github.com/ZJU-FAST-Lab/VID-Dataset and related files: https://github.com/ZJU-FAST-Lab/VID-Flight-Platform are open-sourced.
