2021年5月北京典型城市道路磁场数据

典型城市道路磁场数据，可作为磁基准库，用于车辆磁场匹配定位。由专用测试车辆沿行驶路线实地采集，原始数据包括：高精度位姿数据、三轴矢量磁场数据、高精度行驶里程数据等，经过干扰滤除、空间刻度化处理后，形成等里程间隔的磁场数据，空间分辨率2m，位置基准精度0.1m，航向精度0.05°，磁场数据精度50nT。该磁场数据为同一行驶路线多次重复采集、校验最终获得。

Typical urban road magnetic field dataset, which can serve as a magnetic reference database for vehicle magnetic matching localization, was collected on-site along driving routes using dedicated test vehicles. The raw data includes high-precision pose data, triaxial vector magnetic field data, high-precision driving mileage data, and other relevant measurements. After undergoing interference filtering and spatial scale calibration processing, the dataset is standardized into magnetic field samples with uniform mileage intervals, with a spatial resolution of 2 m, a position reference accuracy of 0.1 m, a heading accuracy of 0.05°, and a magnetic field measurement accuracy of 50 nT. This dataset is finally obtained through multiple repeated collections and validations on the same driving route.
