  LBSTraceClient | 轨迹纠偏类，对行车GPS高精度定位轨迹集合纠偏 Trajectory correction class, correcting the collection of high-precision GPS positioning trajectories for driving
  TraceLocation | 用于轨迹纠偏的一个点的信息，目前该点需要：经度、纬度、速度、方向角（和gps返回一致）、定位时间 Information for a point used in trajectory correction, currently requiring: longitude, latitude, speed, bearing (consistent with GPS return), and positioning time
  TraceOverlay | 用于绘制轨迹纠偏接口回调的一条平滑轨迹 A smooth trajectory for the trajectory correction interface callback
