OpenHPS: Single Floor Fingerprinting and Trajectory Dataset

<strong>Description</strong> This dataset contains fingerprint information of WLAN access points and BLE beacons with a known position and IMU sensor data. Data was collected on the floor of the Web and Information Systems Engineering (WISE) Lab at the VUB (Pleinlaan 9, 3rd floor) with 110 training reference points and 30 test data points. Each reference point was recorded for 20 seconds in four different orientations. More information is given in the README.pdf file included in the dataset. <strong>File Contents</strong> <code>/wlan_aps.csv</code>: Wireless access point information <code>/ble_beacons.csv</code>: BLE beacon positions <code>/misc</code>: Miscelanieous resources <code>/misc/floorplan.png</code>: PNG version of the floorplan <code>/misc/floorplan_medium.png</code>: PNG version of the floorplan (medium quality) <code>/misc/datapoints.svg</code>: Training and test data points visualisation <code>/misc/datapoints.csv</code>: Training data points CSV <code>/misc/testdatapoints.csv</code>: Test data points CSV <code>/misc/spaces.geo.json</code>: GeoJSON feature collection of symbolic spaces <code>/misc/documentation.css</code>: README documentation CSS (unrelated to the dataset) <code>/train</code>: Training data points (110 in 4 orientations) <code>/train/raw</code>: Raw unprocessed data points (not aggregated) <code>/train/raw/wlan_fingerprints.csv</code>: Raw WLAN fingerprints <code>/train/raw/imu_fingerprints.csv</code>: Raw IMU data collection <code>/train/raw/ble_fingerprints.csv</code>: Raw BLE fingerprints <code>/train/aggregated</code>: Processed aggregated data points <code>/train/aggregated/wlan_fingerprints.csv</code>: WLAN fingerprints <code>/train/aggregated/ble_fingerprints.csv</code>: BLE fingerprints <code>/train/aggregated/imu_fingerprints.csv</code>: IMU data collection <code>/train/aggregated/wlan-ble_fingerprints.csv</code>: WLAN and BLE fingerprints merged <code>/test</code>: Test data points (30 in 4 orientations) <code>/test/raw</code>: Raw unprocessed test data points (not aggregated) <code>/test/raw/wlan_fingerprints.csv</code>: Raw WLAN fingerprints <code>/test/raw/imu_fingerprints.csv</code>: Raw IMU data collection <code>/test/raw/ble_fingerprints.csv</code>: Raw BLE fingerprints <code>/test/aggregated</code>: Processed aggregated data points <code>/test/aggregated/wlan_fingerprints.csv</code>: WLAN fingerprints <code>/test/aggregated/ble_fingerprints.csv</code>: BLE fingerprints <code>/test/aggregated/imu_fingerprints.csv</code>: IMU data collection <code>/test/aggregated/wlan-ble_fingerprints.csv</code>: WLAN and BLE fingerprints merged <code>/trajectories</code>: Test trajectories (10) <code>/trajectories/???</code>: Trajectory directory, ??? is the name of the trajectory <code>/trajectories/???/???_ble.csv</code>: BLE advertisements received during the trajectory <code>/trajectories/???/???_imu.csv</code>: IMU data from the trajectory <code>/trajectories/???/???_wlan.csv</code>: WLAN signals received during the trajectory**数据集说明** 本数据集包含已知位置的无线局域网（WLAN）接入点与蓝牙低功耗（BLE）信标的指纹信息，以及惯性测量单元（IMU）传感器数据。数据采集于布鲁塞尔自由大学（VUB）网络与信息系统工程（WISE）实验室的楼层（Pleinlaan 9号3楼），共包含110个训练参考点与30个测试数据点。每个参考点需在四种不同朝向下分别录制20秒。更多详细信息请参阅数据集中附带的README.pdf文件。 **文件内容** `/wlan_aps.csv`：无线接入点信息 `/ble_beacons.csv`：BLE信标位置信息 `/misc`：杂项资源 `/misc/floorplan.png`：楼层平面图的PNG格式文件 `/misc/floorplan_medium.png`：中等画质版本的楼层平面图PNG文件 `/misc/datapoints.svg`：训练与测试数据点可视化文件 `/misc/datapoints.csv`：训练数据点CSV文件 `/misc/testdatapoints.csv`：测试数据点CSV文件 `/misc/spaces.geo.json`：符号化空间的GeoJSON要素集合 `/misc/documentation.css`：README文档的样式表（与数据集本体无关） `/train`：训练数据点（共110个，涵盖4种朝向） `/train/raw`：未经过处理的原始数据点（未聚合） `/train/raw/wlan_fingerprints.csv`：原始WLAN指纹数据 `/train/raw/imu_fingerprints.csv`：原始IMU传感器数据 `/train/raw/ble_fingerprints.csv`：原始BLE指纹数据 `/train/aggregated`：经过处理的聚合数据点 `/train/aggregated/wlan_fingerprints.csv`：WLAN指纹数据 `/train/aggregated/ble_fingerprints.csv`：BLE指纹数据 `/train/aggregated/imu_fingerprints.csv`：IMU传感器数据 `/train/aggregated/wlan-ble_fingerprints.csv`：WLAN与BLE指纹融合数据 `/test`：测试数据点（共30个，涵盖4种朝向） `/test/raw`：未经过处理的原始测试数据点（未聚合） `/test/raw/wlan_fingerprints.csv`：原始WLAN指纹数据 `/test/raw/imu_fingerprints.csv`：原始IMU传感器数据 `/test/raw/ble_fingerprints.csv`：原始BLE指纹数据 `/test/aggregated`：经过处理的聚合测试数据点 `/test/aggregated/wlan_fingerprints.csv`：WLAN指纹数据 `/test/aggregated/ble_fingerprints.csv`：BLE指纹数据 `/test/aggregated/imu_fingerprints.csv`：IMU传感器数据 `/test/aggregated/wlan-ble_fingerprints.csv`：WLAN与BLE指纹融合数据 `/trajectories`：测试轨迹（共10条） `/trajectories/???`：轨迹目录，其中???为轨迹名称 `/trajectories/???/???_ble.csv`：轨迹采集期间接收到的BLE广播数据 `/trajectories/???/???_imu.csv`：轨迹采集期间的IMU传感器数据 `/trajectories/???/???_wlan.csv`：轨迹采集期间接收到的WLAN信号数据
