This paper presents a comprehensive dataset intended to evaluate passive Human Activity Recognition (HAR) and localization techniques with measurements obtained from synchronized Radio-Frequency (RF) devices and vision-based sensors. The dataset consists of RF data including Channel State Information (CSI) extracted from a WiFi Network Interface Card (NIC), Passive WiFi Radar (PWR) built upon a Software Defined Radio (SDR) platform, and Ultra-Wideband (UWB) signals acquired via commercial off-the-shelf hardware. It also consists of vision/Infra-red based data acquired from Kinect sensors. Approximately 8 hours of annotated measurements are provided, which are collected across two rooms from 6 participants performing 6 daily activities. This dataset can be exploited to advance WiFi and vision-based HAR, for example, using pattern recognition, skeletal representation, deep learning algorithms or other novel approaches to accurately recognize human activities. Furthermore, it can potentially be used to passively track a human in an indoor environment. Such datasets are key tools required for the development of new algorithms and methods in the context of smart homes, elderly care, and surveillance applications.
本文提供了一个综合数据集,旨在评估基于射频(RF)设备和基于视觉传感器的被动人体活动识别(HAR)和定位技术。该数据集包括从 Wi-Fi 网络接口卡(NIC)中提取的射频数据,包括信道状态信息(CSI),基于软件定义无线电(SDR)平台构建的无源 Wi-Fi 雷达(PWR),以及通过商用现成硬件获取的超宽带(UWB)信号。它还包括从 Kinect 传感器获取的基于视觉/红外线的数据。该数据集提供了大约 8 小时的标注测量值,这些测量值是在两个房间中从 6 名参与者进行 6 项日常活动中收集的。该数据集可用于推进基于 Wi-Fi 和基于视觉的 HAR,例如使用模式识别、骨骼表示、深度学习算法或其他新方法来准确识别人体活动。此外,它还有可能用于在室内环境中被动跟踪人类。在智能家居、老年人护理和监控应用等背景下,此类数据集是开发新算法和方法所需的关键工具。
