场景图

LGW事件功能为车机直接发布事件给周边车机，不涉及移动网络。因此，要求该功能在本地实现：

LGW原始数据的获取 -> 二进制解码 -> 轨迹数据的本地匹配 -> 生成事件的本地渲染 -> MPP判断&排序 -> Combi popup/IFA/PSD。

其中，轨迹数据的本地匹配需要定位引擎的能力支持。

核心接口

添加PosGraspRoadResult信息观察者

void com.autonavi.gbl.pos.PosService.addGraspRoadResultObserver(IPosGraspRoadResultObserver observer)\n

删除PosGraspRoadResult信息观察者

void com.autonavi.gbl.pos.PosService.removeGraspRoadResultObserver(IPosGraspRoadResultObserver observer)

输入事件历史轨迹信息

void com.autonavi.gbl.pos.PosService.setEventTrackHistory(EventTrackHistory track)

轨迹本地匹配抓路结果通知

IPosGraspRoadResultObserver.onGraspRoadResult(GraspRoadResult graspRoadResult)
