为获取上述`channel`,需要启动`GPS``Localization``Velodyne`三个模块,`GPS``Localization`模块的启动请参考<font color='red'>定位模块配置文档</font>`Velodyne`模块的启动请参考<font color='red'>感知传感器集成文档</font>。由于GNSS设备的限制,`/apollo/sensor/gnss/odometry``/apollo/sensor/gnss/ins_stat`这两个`channel`不能由GNSS设备直接给出,需要借助`/apollo/modules/tools/sensor_calibration/`下的两个脚本工具。在`localization`模块正常启动且输出`/apollo/localization/pose`数据时,在不同终端分别执行`python modules/tools/sensor_calibration/ins_stat_publisher.py``python modules/tools/sensor_calibration/odom_publisher.py`两个命令,便可以分别产生`/apollo/sensor/gnss/ins_stat``/apollo/sensor/gnss/odometry`这两个`channel`

**注意**:在执行`sensor_calibration/ins_stat_publisher.py`脚本前,请务必检查`/apollo/sensor/gnss/best_pose`中GPS信号质量,确保GPS信号质量为`NARROW_INT`时,才可以使用`ins_stat_publisher.py`脚本。在录制数据前,应首先确保`modules/localization/conf/localization.conf`文件中的`enable_lidar_localization`设置为`false`,待地图制作完成后如果需要msf定位,再修改为true。

## 使用虚拟车道线云服务生成虚拟车道线

### 1. 上传数据至BOS

在BOS bucket中新建目录virtual_lane,作为后续云标定服务读取数据的`Input Data Path`把前面录制的数据 包以及lidar_GNSS外参文件拷贝至该目录。目录结构如图所示:

将上图中的2020-01-6-08-08-42整个文件夹拷贝到/apollo/modules/data/下,重命名为自己的地图名字(例如gongyuan),重启DreamView即可在地图下拉框中看到自己刚添加的地图。
