OpenCSI
收藏资源简介:
OpenCSI是由瑞士联邦理工学院开发的室内定位数据集,专注于基于信道状态信息(CSI)的指纹识别技术。该数据集在瑞士电信数字实验室的办公环境中收集,覆盖面积为3.5米x5米,通过安装在轮式机器人上的软件定义无线电(SDR)自动收集数据。数据集包含大约4000个参考点(RPs),每个点记录了约1000次连续的CSI指纹。OpenCSI旨在解决室内环境中的定位问题,特别是在全球导航卫星系统(如GPS)精度不足的情况下,利用CSI的丰富信息进行精确室内定位。
OpenCSI is an indoor positioning dataset developed by ETH Zurich, focusing on fingerprinting technology based on Channel State Information (CSI). The dataset was collected in an office environment at the Swisscom Digital Lab, spanning a coverage area of 3.5 m × 5 m, with data automatically gathered via a software-defined radio (SDR) mounted on a wheeled robot. It contains approximately 4000 Reference Points (RPs), where around 1000 consecutive CSI fingerprints are recorded at each point. OpenCSI targets indoor positioning challenges, especially enabling accurate indoor positioning by leveraging the rich information carried by CSI when Global Navigation Satellite Systems (e.g., GPS) fail to provide sufficient positioning accuracy.
